Horse Aging Poem

THE AGE OF A HORSE



To tell the age of any horse
Inspect the lower jaw of course
Six front teeth the tale will tell
And every fear and doubt dispel

Two middle 'nippers' you behold
Before the colt is two weeks old
Before eight weeks two more will come
At eight months the corners cut the gum

The cupping grooves will disappear
From the middle two in just one year
Two years gone from the second pair,
At three years, the "corners" too, are bare

At two the middle incisors drop
At three the second pair can't stop
When four years old the third pair shows
At five, a full new set she shows

The deep black spots will pass from view
At six years from the middle two
The second pair at seven years
At eight the corner spot disappears

From middle nippers upper jaw
By nine the black spots withdraw
The second pair at ten are bright
Eleven finds the corners' light.

At ten, Galvayne's Groove begins
Outside upper nipper, my friends
From the gum the dark line falls
Until twenty, when time itself calls.

As more years pass, wise horsemen know
The oval nippers, three-sided grow.
The aging incisors loosen and spread,
Until that time, which we all dread.




The horse pictured at the top is ~4 years old. At 4½ the lower corner baby nipper will be replaced the permanent incisor. Note the difference in the size of the baby teeth compared to the permanent teeth.

Nippers are the incisors, the grass acquisition teeth. It is the incisors we assess to age the horse.

This is the revised version to "every fear and doubt dispel" Of course, this aging system depends on the horse being examined for age having lived a natural existence, grazing with others most all her life, continuous lifetime foraging as the horse evolved to do. Grazing teeth wear consistently, and aging is quite accurate, for horses raised up here on the Blackfeet Indian Reservation. Some, however, may not let you look them in the mouth. Those horses have to be aged from a distance, and many Blackfeet have quite an eye for that, as well. 

Mind you all, stabled horses' teeth with wear differently than horses offered a natural grazing and socializing existence, especially those stabled horses who are often deprived of forage and locomotion for periods of time. Horses need to move and forage most all the time to maintain health, vigor, and trainability. 
The feeding of artificial grains and the development of stereotypic behaviors due to deprivations of forage, friends, and locomotion alter teeth wear dramatically, as well. 
This goes without saying: 
Horses who graze continuously in natural settings often have healthier teeth and lives than stabled horses. Look all horses in the mouth, please, each and every one, every time, my friends.

How Horses Learn

Horses learn as people learn. There are a variety of methods and modes of learning. Horses are born to learn, and learn from their first breath to their last. Whenever horses are around humans, they are learning. They learn and remember most everything any human teaches them, including behaviours not intended to be taught. Appreciating learning science is essential to successful horsemanship.

The foal’s first teacher is her dam. Once the mare catches her breath following parturition, she begins teaching her foal. She utilizes operant conditioning to help the foal rise and suck. She applies gentle pressure to the foal with her muzzle in rhythm with the foal’s movement. When the foal moves in the direction best suited to rising as the mare suggests, the mare releases the pressure, conditioning the foal. This operant conditioning that utilizes negative reinforcement teaches the foal the best method to rise and stand to find a nipple, and subsequently suck. The mare also utilizes positive reinforcement to teach her foal. She rewards appropriate behaviors with milk, rubs, and nickers.

Once the foal learns to nurse, the foal learns to move out alongside her mother, developing her locomotory skills. The foal develops her innate movements under the mother's guidance and tutelage. Many behaviours are innate and instinctual, but all are best served to be honed by the mare’s example. Rewards, cues, protections, support and guidance develop the foals learning abilities.
Foals are born to run soon after birth. Within hours many can and do run when afforded the opportunity of open space in which to do so. Foals are precocious, meaning they are born with a well-developed nervous system. Altricial species such as the dog and humans are born helpless and require weeks for the nervous system to develop into a moving mammal. Not so the foal.
Precocial species are not only able to run, they are able to learn shortly after birth. The mare and foal are best served to be provided with a natural open setting in which to develop their learning and moving about. Green open pastures provide the best teaching and learning opportunities for the mare and foal. A stall or stable is perhaps the worst place for the mare to effectively teach the foal. 
It is critical the foal learn from the mare, and later the herd, so as to be amenable to human training later in life. Social learning is critical for the foal to grow up into a teachable, trainable willing partner. 
During the first hours of life, the foal becomes a horse. This imprint phase is a unique and critical learning phase that molds the foal into a horse. The foal absorbs the behaviour of the dam utilizing social learning. The first hours and days of life is the most critical learning period of the foal, and this learning should be supported and nurtured from a distance by humans. Social learning is critical for all species, and is particularly important for group survivalists such as the horse. The horse is taught to be a horse by the dam and the herd. Learning the social constructs of herd life is critical for group survival. As well, learning the social constructs of the herd prepares the foal to be taught by humans later in life.

Accomplished horse trainers utilize all the teaching strategies that the mare uses to teach her foal. Operant conditioning, associative learning, classical conditioning, habituation, desensitization, and social learning are all taught to the foal by the mare. It is critical the mare be allowed to teach the foal in as natural a setting as possible so that humans can later train the horse using the principles taught to the foal by the mare. 

All horse trainers should learn, know, and appreciate the scientific terms regarding learning (training). 
The traditional training of horses utilizes negative reinforcement. All horses are trained utilizing negative reinforcement as the primary method to teach responses to specific cues. Negative does not imply that the training method is unacceptable or bad for the horse. Mares teach their foals using negative reinforcement: Pressure is applied, and then released when the horse or foal gives the correct response. So then, pressure followed by release to the desired response is negative reinforcement. Remember the terms negative and positive have nothing to do with good or bad when used in the context of training and teaching horses. Negative means taking something away. In behavioral learning terms, positive connotes adding something, such as a reward, as in positive reinforcement, or adding punishment, which is termed positive punishment, which can be unacceptable despite the terminology. 
Positive reinforcement is adding something, such as food or a rubbing reward.
Negative reinforcement can be enhanced with positive reinforcment. 1. The pressure is applied such as a pulling on the rein. 2. The horse responds by turning and the pressure is immediately released (this release is the reinforcement, but since pressure was first applied, the pressure has to be removed, which is a taking away, a negative act, thus the term negative reinforcement; how all horses are trained). 3. Once the pressure is released, or as the pressure is released, the horse can be rewarded with rubbing or verbal praise, which is using the addition of positive reinforcement to train. Once the horse has responded to the pressure or cue, and the pressure is released, another something can be added to enhance the behavior, to increase the likelihood of the behavior repeating itself. This end act of reward, if utilized, is termed positive reinforcement. The release preceding the rub, however remains negative reinforcement. For those of you who are interested in understanding the principles of horsetraining and horsemanship, you must learn the terminology and concepts of learning theory, first.
4. If the horse turns the other way and bolts, positive punishment is sometimes used to teach, such as painfully jerking the horse around with the reins, or spurring to punish the unwanted response. Of course, the horse who bolts the other way has not been properly taught or prepared (Culpa equestribus non equus). Jerking the horse around is scientifically termed positive punishment. Although termed positive punishment, this type of training (excessive or predominant use of punishment) can be bad for horses and result in a fragile unreliable relationship. Remember this: the horse always has the last word.
Willing partnerships are preferred to indentured servitude (fear of punishment).

The combination of negative reinforcement accompanied by positive rewards is operant conditioning, sometimes called instrumental conditioning, often known as horsemanship.
Classical conditioning is conditioning by association, and classical conditioning plays a large role in horsetraining, as well, as those of you interested will learn, and learn well, just like a horse can learn so well.
The dam teaches the foal how to be a horse using all these techniques, and so do humans when they train horses in later life. For a horse to be trained by a human, a foal must grow to be a horse, and only the mare and other horses can teach a foal to be a horse. Man has no role in teaching a foal to be a horse, as that is the mare's domain, and her herd's. Foals that grow up fully a horse are the horses that are simplest to train.
Shared sociality. Kinetic empathy. Learn to train as the mare trains. Let the mare train the foal, please.

Horses are horses. Folk are folk. They live together, share a social fabric. Horses and horsefolk share many aspects of living, including communication and learning.

Fundamentals of Racehorse Health: Enhancing the Soundness of Wind and Limb


Horses evolved as social grazers of the plains, group survivalists moving and grazing together most all of the time day and night. During their 60-million-year evolution, horses came to depend upon near-constant movement to maintain health and vigor of wind and limb. 
The horse's long-evolved nature of the need for constant movement follows horses into the stable to this day. 


Abundant daily locomotion of stabled racehorses is essential to develop, enhance, and maintain pulmonary and musculoskeletal soundness. Abundant daily walking and grazing are easy to accomplish at nearly all of the American racing venues. Time seems to be only restraint, taking the time to care for stabled horses as they should be cared for to reduce their current dependence on medication and the resultant untoward side-effects of breakdowns and sudden death. 
Something as seminal and simple as abundant daily walking to improve racing safety and integrity cannot be overlooked and ignored any longer. Horses are born to walk, and walk the must to maintain vigor and health. The current practices, both pharmaceutical and husbandry-related, have failed the horses, thus the United States continues to experience unacceptable breakdown rates not experienced or tolerated elsewhere in the world.
Education is the key, education of those caring for the horses and responsible for their durability. Stabled racehorses require miles of daily walking to induce, maintain, and enhance musculoskeletal soundness. The same walking activity that enhances pulmonary health, enhances limb health and integrity. Lasix has allowed trainers to lock their horses down most of the day, resulting in limb fragility, which is expressed as breakdowns at the race track. The long term-solution lies not so much in regulation as education.

Please note, that when people are hospitalized and bedridden, some of earliest medical personnel to attend them are respiratory therapists. The respiratory therapists, understanding how locomotion is essential for respiratory function, employ a variety of lung exercises and pulmonary assessments to make sure the pulmonary health of the of the hospitalized patients is maintained. Racehorses are for all practical pulmonary purposes; hospitalized. Locomotion and movement are restricted and deprived by stabling. Specific pulmonary conditioning efforts are necessary to enhance and maintain pulmonary health and resilience of all stabled performance horses. For a horse, to move is to breath deeply and healthily, and to breath is to move. When stabling is required, natural must be-recreated in the stable, or the horse will suffer deterioration of soundness of both wind and limb.
Pulmonary and limb health are heavily dependent upon abundant daily locomotion. America's legalized pre-race Lasix allows pulmonary health to be compromised, the pharmaceutical scrim responsible for overall racehorse fragility. Pre-race Lasix allows trainers to race horses deprived of appropriate pulmonary conditioning. Restricted locomotion results in lung (and limb) deterioration, which is the primary basis for all of the breakdown and safety issues plaguing the sport. Lasix facilitates this substandard horsemanship that is responsible for much of the contemporary racehorse fragility. 
Day before injections of NSAIDs likewise perpetuate vulnerability to catastrophic injuries. Pulmonary health is connected to limb health. To allow deterioration of one system is to allow deterioration of the other. Lasix facilitates the racing of horses with compromised lungs. When the lungs are allowed to deteriorate by restricted locomotion, the limbs deteriorate likewise. Bone density and joint integrity are dependent on miles of daily movement, as near-constant movement is the essential nature of horses. Digestion, metabolism, hoof health and durability are all dependent on abundant daily locomotion.
Education can improve the health and welfare of horses.
The key to equine welfare lies in equine behavior education, which delivers an understanding and appreciation of pulmonary and limb health and soundness, and what is required to assure soundness of wind and limb. The same conditioning protocols that ensure pulmonary health and resistance to EIPH are the same protocols that enhance soundness of limb. The solution to improve racing health, soundness, safety, and integrity are relatively simple, and are based on the science of equine behavior, and the need for horses to receive abundant daily locomotion in addition to their race-conditioning regimens.





The solution to manage EIPH is not pre-race intravenous drugs, the solution is to breed, develop, condition, stable, train and exercise horses in a horse-sensitive fashion that provides abundant lifetime locomotion to sustain and enhance the respiratory resilience necessary to race. Pulmonary health is reflective of overall health and soundness in horses. The daily locomotion that enhances pulmonary health concomitantly enhances soundness of limb.

In order to sustain pulmonary and musculoskeletal health, natural conditions need to be re-created in the stable. Constant foraging, grazing, socializing and movement maintain and develop joint and bone health, hoof health, metabolic health and pulmonary health, and, of course, behavioural health. In order for lungs and legs to stay healthy, horses need movement, more movement than American trainers currently provide their population of stabled horses. 

Movement is what is most often missing in a racehorse’s stabled life. To move is to breathe for a horse. Moving and breathing are intertwined physiologically, as are movement and limb integrity. Trainers must facilitate more daily walking and lung and limb development exercises for their stabled horses. Movement, grazing, and socialization enhance equine welfare while conditioning healthy durable lungs. Pulmonary resilience and health are dependent on miles of daily walking. Horsemanship and appropriate husbandry are the appropriate solutions to manage pulmonary health, not pre-race medication.

Limb soundness, pulmonary health, endurance, and resistance to EIPH are dependent on near constant movement and walking in addition to the daily conditioning routines. To keep lungs healthy and limbs sound, American trainers have to better care for their horses, much as the international trainers are required to do who are not allowed to utilize the pharmaceutical scrim Lasix.
 Where Lasix is not utilized racing is safer, the reason being that horses are required to be better cared for where pharmaceutical racing scrims are forbidden.

Appreciating Horses--Introduction to Equine Behaviour

Learn to see as the horse sees.

Horses keep an eye on people, a keen and knowing eye. Dr Gustafson teaches equestrians of all disciplines to learn how to keep an eye on their horses. Awareness of the horses is the art of horsemanship.


 By appreciating horses' long evolved nature as social grazers of the plains and group survivalists, students of equine behaviour readily learn to blend with their horses to consistently keep them happy, healthy, and willing to win. When horsefolk learn to become part of the horse herd, they are able to achieve willing and winning partnerships with their horses. Horses form strong pair bonds. By appreciating the nature of horses, humans can forge deep bonds with their horse, allowing achievements much greater that the sum of horse and rider.






Many begin their horse journey unknowing what awaits them, much as horses began their journey through time 60 million years ago before merging societies with mankind several thousand years ago. Three million years ago the footsteps of primitive man were found fossilized next to the hoofprints of ancient horses in what is now Kenya, suggesting that humans have been contemplating horses for some time. It was not until perhaps ten to twenty thousand years ago that man began the dance of domestication with horse, the horse has become Equus caballus
There is archeological evidence that man formed a close relationship with horses by 5500 years ago in Botai, Khazakstan where the horsefolk kept and milked horses, probably rode them, this after millenia of hunting horses for food. Both trained and wild horses co-existed in this realm south of Russia and west of China. Trained horses soon spread throughout the world, civilization of man the result. By the early 20th century the predecessor to man's newest animal partner, the tarpan, had gone extinct. To the best of our knowledge, all horses today are descended from domesticated selectively bred horses.

The progenitor of the horse, the tarpan Equus ferus, went missing from our planet in 1918. One gauge of domestication is the extinction of the progenitor, and mankind has managed that with the horse, extinguishing that line that did not cooperate as Equus caballus did. Today’s horse is with us to stay, it seems, and can live with humans, or without them. Ten thousand years is not a lot of time in the larger scale of the horse’s 60 million year evolution to become a social grazers of the plains. Similar social constructs shared between man and horse facilitated an eventual merger. By five thousand years ago, horse and mankind had become co-dependent on the other.

Horsefolk remain enticed by horses. We find ourselves still attempting to appreciate how this human/horse relationship came to be, and where the relationship is headed, much as mankind has contemplated since the first girl grabbed a mane and swung on a horse to become a partner with the flighty, powerful (but trainable and tamable) grazer of the plains.
The most important concept to appreciate is the social nature of horses. Horses require other horses on a near-constant basis for physical and behavioural health. Equine behaviour is heavily influenced by socialization. Horses are required to grow up to be horses as taught by horses to lead behaviourally healthy lives with humans. The mare teaches the foal to be a horses, and this bonding and teaching process should be allowed to develop as natural as possible. Once the mare and herd have taught the foal to be a horse, the training can begin. When grown, horses must be allowed to be horses with other horses to enhance willing partnerships with horsefolk. When stabled, natural must be re-created for the horse as we shall see. As we shall see, the last place a horse evolved to live is in a stall. When horses are stalled, we must re-create their constant need for friends, forage, and locomotion. 






Horses are a quiet species. They prefer calm, and learn most efficiently in tranquil, familiar settings. In emulating the horse, our interactions here will be communicatively soft and calm so as not to unnecessarily upset or excite our herd. Now if there is something valid to be concerned about, say a certain enlightenment, or concern about a welfare issue, or perhaps a training or stabling method that does not align with the horse's perspective, then we appropriately share our views with the others.



We all know what we want from our horses. Equine behavior is the science of what our horses want and need from us. To succeed in our endeavors with horses (whatever equine goals or pursuits), our horses are best served to receive what they preferentially need and want behaviourally, nutritionally, socially, physically, environmentally, visually, and metabolically. In order to properly care for horses and successfully teach horses, we must know them, the diligent social grazers of the plains they are. 
Rather than dissimilar to us, horses are much like us. In this class we will focus on humankind's social and communicative similarities to horses. As with people, strong interdependence develops between individuals, intense social pair and herd bonds. Horses need other horses, and when they are dependent on people, they need a lot of time spent with those horsefolk and their other horses. 
An interdependence also exists between health and locomotion. Horses evolved to be near-constant walkers and grazers. Horse health remains dependent on locomotion and grazing, or facsimiles thereof. If horses are not allowed to exercise freely, or socialize with other familiar horses, nibbling and chewing as they evolved to do, they develop strategies to maintain the motion and oral security they feel they need to survive. These strategies to survive develop into what humans call stereotypies. Here we do not call them vices, as vices infer the horse is at fault, but we will learn who is really at fault, and it is not the horse after all. 


The primary premise of equine behavioural health is this: In natural settings, horses walk and graze together two thirds of the time. They take a step and graze, another step or two, always observing their surroundings, grazing while in touch with other members of the herd unless playing, dozing or sleeping under the watch of others. 
Horses that are not afforded the opportunity to graze and walk much of the time take up with stereotypic behaviours to replicate essential locomotion.
Make sure your stabled horses receive miles of daily walking each day to enhance and sustain their behavioral and physical health.

Managing Racehorse Health without PreRace Medication



Horses evolved as social grazers of the plains, group survivalists moving and grazing together most all of the time.

Full article as it appeared in the NYTimes:


Horses evolved as social grazers of the plains, group survivalists moving and grazing together most all of the time. During their 60-million-year evolution, horses came to require near-constant forage, friends and locomotion to maintain health and vigor of wind and limb.
Despite domestication and selective breeding, today’s racehorses are no exception. Although horses are extremely adaptable, the last place a horse evolved to live is in a stall, alone, with limited space to move and forage about with others. The solution to manage bleeding in racehorses is to breed, develop, teach, train and care for horses in a horse-sensitive fashion that provides abundant lifetime locomotion and socialization. Pulmonary health is reflective of overall health and soundness in horses.
In order to maintain pulmonary health, natural conditions need to be re-created in the stable. Horses prefer to graze together and move nearly constantly. Constant foraging, grazing, socializing and moving are essential for joint and bone health, hoof health, metabolic health and pulmonary health, and, of course, mental health. In order for lungs to stay healthy, horses need movement, more movement than American trainers currently provide the population of stabled. Horses communicate with movement and sustain physiologic and metabolic health via near-constant locomotion. Movement is what is most often missing in a racehorse’s stabled life.
Walking throughout the day enhances and maintains lung health. Stabled horses need hours of walking each day, more walking than most are currently afforded. Veterinarians who manage racehorse health need to ensure that their patients are provided with adequate daily locomotion. The movement of training and track conditioning are not adequate to condition healthy lungs throughout the rest of the day, as lung health requires 24/7 movement. For a horse, moving is breathing. Abundant on-track and off-track locomotion is necessary to condition a horse’s lungs and to provide the necessary resilience to withstand the rigors of racing.
Lungs deteriorate when movement is restricted. Horses breath all day long, and near-constant movement is required much of the day to assist their breathing to maintain pulmonary flexibility and vigor. Plentiful walking enhances breathing and lung health. Swimming and doing lunges are also appropriate lung-conditioning activities. Grazing while casually walking clears the airways. Hand grazing may be the best lung-healthy activity of all. Racetracks need to provide abundant hand-grazing opportunities for all of the stabled horses, and the green grass needs to be appropriate grazing grass. Kentucky limestone grass is always best, it seems.
Training over hills and dales, as well as walking up and down inclines helps develop and sustain pulmonary vigor. When horses are locked in a stall a large percentage of the time, their lungs deteriorate. Stabling that does not afford abundant movement and head-down grazing and foraging impairs lung health, making horses vulnerable to bleed when exerted in a race. The cause of exercise-induced pulmonary hemorrhage is insensitive and deficient stabling and husbandry practices and includes diagnostic failures to detect bleeding during training.
The care that establishes and enhances pulmonary health and endurance in horses is the same care that enriches stabled horses’ lives. Pulmonary care is providing the same near-constant movement that keeps racehorses’ musculoskeletal systems sound. It is the care that keeps horses on their feet during races. Horses must remain sound of limb to ensure lung soundness, and they must remain sound of lung to achieve and maintain limb soundness. Afternoon and evening hand walking and hand grazing are essential to develop and sustain lungs and limbs fit to race.
Horses with healthy lungs are content and fulfilled horses whose lives their caretakers adequately, if not extensively, enrich. Lung health is supported by limb health. Breathing and running are biologically intertwined on the track, a breath per stride. To stride correctly is to breathe correctly. To breathe correctly is to breathe soundly, and race sound.
Horses who are bred, socialized, and developed properly from birth, and who train while living enriched stable lives are seldom likely to experience performance-impairing E.I.P.H. while racing. They are more apt to stay sound. Humane care of the horse prevents bleeding. Pulmonary health is reflective of appropriate husbandry, breeding, training, nutrition, and the abundant provisions of forage, friends, and perhaps most importantly, locomotion. Bleeding in a race is reflective of inadequate care and preparation, of miscalculations and untoward medication practices. Lasix perpetuates substandard horsemanship, artificially suppressing the untoward result (bleeding) of inadequate preparation of the thoroughbred.
Genetics play a role in pulmonary health and physical durability. Lasix perpetuates genetic weakness by allowing ailing horses to prevail and sow their seeds of pharmaceutical dependence. Running sore causes lungs to bleed. Lasix manages a wide variety of unsoundness, as do the cortisones and NSAIDs (bute and similar drugs). These anti-inflammatory drugs aggravate coagulation processes. Rather than drugs, pulmonary health is dependent on appropriate breeding and proper development for the vigor, durability and endurance thoroughbred racing demands. Drugs are not the solution. Competent horsemanship is the solution. Genetic dosage, behavioral and physical development, socialization, training, and locomotion husbandry are the keys to racehorse soundness, lung health, stamina, and durability. The causes of E.I.P.H. are no mystery to seasoned race folk. Horses prone to bleed are those horses that are mistakenly bred, inadequately developed and inappropriately stabled and trained.
Horses evolved in the open spaces of the northern hemisphere and require the cleanest, purest air to thrive and develop healthy lungs and hearts. Stable air needs to be constantly refreshed to maintain pulmonary health. Ventilation is essential, and enclosed structures are often inappropriate. Barn design needs to provide both clean air and abundant locomotion. Bedding is critical. Clean straw provides the most movement by simulating grazing. Horses stalled on straw are noted to move about with their heads down nibbling and exploring for hours, recreating nature to some degree, keeping their lungs healthy with movement, their respiratory tracts drained by all the head-down nibbling and grazing. Horses need near-constant head-down movement to maintain optimum lung health. Long-standing horses’ lungs deteriorate quickly. Not only does near-constant movement maintain and enhance pulmonary health, abundant locomotion maintains metabolic health, joint and bone health, hoof health and digestive health.
To enhance lung health is to enhance the overall health and soundness of the racehorse. Racing appears much safer in Lasix-free jurisdictions, where the drug crutch is not allowed, because the drug crutch allows horses to be cared for in a substandard fashion. (A link to the transcript from the Kentucky Raceday Medication Committee hearing is here.) Drugs are not allowed to replace appropriate care and training in Asia and Europe, and raceday drugs should be barred in America as they are in the rest of the civilized world. The stabled racehorse has to be carefully and humanely cared for and nourished in a holistic fashion, both physically and behaviorally, to win and stay healthy to win again.

A Contemporary Approach to Equine Welfare

A CONTEMPORARY APPROACH TO EQUINE WELFARE



This is a review of the current behavioural science regarding the horse.  This paper is a primer on equine welfare, and portrays the educational approach utilized to help horsefolk fulfill the health and welfare needs of horses from the horse’s perspective, rather than from the human perspective.  Behavioural study and appreciation of the evolved nature of horses provide the foundation for the contemporary principles of equine welfare.  Friends, forage and locomotion are the long-evolved requirements for healthy horses to facilitate optimum health, performance and healing. 




Equine Behaviour Through Time

Horses began their journey through time 60 million years ago. Three million years ago the footsteps of humans were fossilized next to the hoofprints of horses, suggesting that humans have been contemplating horses for some time. But it was not until perhaps ten thousand years ago that human societies began the dance of domestication with the horse. Over thousands of years, perhaps tens of thousands of years, the horse herds gradually merged with human societies. A shared language described by contemporary scientists as kinetic empathy, a language of movement, and similar compatible social structures facilitated the merging of the two species.

There is archeological evidence that humans had formed an intimate and intermingled relationship with horses by 5500 years ago in Botai, where the horsefolk stabled and milked horses, and probably rode them. Horses provided these early horsefolk with much of the essentials they needed for group survival. It is interesting to note that large domestic dogs lived with these early horsefolk as well, but no other domestic animals. To understand the domestication process is to enhance our appreciation of equine behaviour. Horses apparently became domesticated because they found a niche with people long ago on the steppes of Kazakhstan. Both trained and wild horses existed in this realm south of Russia and west of China. A population of horses more amenable to captivity and taming than their wild counterparts likely provided the stock for the first horse societies. Rather than plucking wild horses out of the wild and taming them, it is thought that over tens of thousands of years a relationship developed in a shared niche.

By the early 20th century the closest living relative to Equus caballus, the Tarpan, had gone extinct. No truly wild horses remain. All of today’s caballine horses are descended from an original, and possibly separate, population of horses that were amenable to being tamed and selectively bred by humans. It appears to have taken tens of thousands of years to fully domesticate the horse, and to eventually attain control of breeding. Breeding initially consisted primarily of selection for docility and amenability to captivity, and later milking, riding, driving, and stabling. In contemporary culture, selective breeding often involves selecting for the best athlete, or attempting to select for the best athlete. In addition to genetics, this presentation will focus on the socialization aspect of raising horses, and portray the importance of nurture on the eventual behavioral and physical health of the adult athlete.

No longer does human society depend on horse society for survival as it once did. Although still bred for trainability, more and more horses are today bred for specific performance goals. These days, horses provide people with entertainment, recreation, sport, esteem, performance, and pleasure, and, as ever, but in fewer and fewer reaches, utility. Other than stockfolk, few others rely on horses to sustain a pastoral livelihood. This new role of the horse requires renewed studies and considerations of equine behavior.

Horsefolk and veterinarians alike remain enticed and intrigued by horses. The science of equine behaviour attempts to appreciate just who horses are, and from the horse perspective. To appreciate the horse perspective, behaviourists explore the evolution and domestication of the horse. We continue to find ourselves attempting to appreciate how the current human/horse relationship came to be so as to facilitate a smooth trouble free relationship with our horses. As well, appropriate breeding, socialization, and training of horses helps minimize behavioural wastage.

To understand where our relationship with the horse is headed, veterinary behaviour practitioners attempt to see where the human/horse relationship has been, and to subsequently help modify and refine the relationship to favour the horse. Humans continue to live with horses and continue to learn from them, as all horsefolk have through time.  Now, however, much less time is spent with horses and learning from horses, so contemporary practitioners must research and make themselves aware of the behavioural principles that were once gleaned from a near-constant exposure to horses through all stages of their development. We study the evolution and domestication of the horse to better help us appreciate the horses we have in our hands today. Evolution and domestication provide a basis for the understanding of equine behaviour. Man has attempted to refine his relationship with the horse ever since the first kid grabbed a mane and swung atop a horse. To become a partner with the flighty, powerful (but trainable and tamable) grazer of the plains remains the horsefolk goal.

Appreciation and sensitivity to all of our caballine horses' evolved preferences results in optimum health and soundness, and therefore optimum performance. A horse cannot be coerced to win the Kentucky Derby. The people must work with the horse, and from the horse’s view. If we understand equine behaviour, we understand what makes horses do our bidding, and do it willingly and well. To this day, horses seek to appease their domesticators much as they appease others in horse societies and herds. Horses are willing learners. This learning behavior is a result of evolutionary development of a complex social lifestyle. More recently, selective breeding has influenced equine behaviour.

The nature of the horse is enhanced by the horse’s social development. Appropriate socialization with other horses in the herd pasture setting best prepares horses to be subsequently trained by horsefolk. Pastured horses train up and learn more efficiently than stabled horses. The appropriate, efficient, and considerate training of horses is highly dependent on their previous socialization by the dam and other horses, as well as their current husbandry situation. Trainability is heavily influenced by the intensity and type of stabling and husbandry, not to mention the type of training. In the latest revolution of horsemanship, the area of appropriate socialization and stabling has not received the attention it deserves.

Horses are a quiet species. They prefer calm, and learn most efficiently in tranquil, familiar settings. Horses must know and be comfortable and secure in their environment to be able to learn as horsefolk hope them to learn. Horsefolk all know what we want from our horses, however in this paper I shall present the science of what our horses want and need from humans, the science of equine behaviour. Equine behaviour is not only the basis of training and trainability, but also the very basis of equine health. To succeed in our endeavors with horses (whatever the our equine goals or pursuits), our horses are best served to receive what they preferentially need and require behaviourally, nutritionally, socially, physically, environmentally, visually, and metabolically. In order to properly care for horses and successfully teach and train horses, horsefolk must know horses. They must know who the gregarious grazers of the plains are. They must know how to properly socialize horses through their growth phase to ensure that their horses grow up to be horses. Horses raised out of the herd context are vulnerable to behavioural insecurities later in life. Most behavioural wastage is due to improper socialization and husbandry.


Rather than being dissimilar to us, horses are much like us. In this presentation, I attempt to clarify humankind's social and communicative similarities to horses. As with people, strong social bonds develop between individual horses and groups of horses. This herd nature results in intense social pair and herd bonds. Horses need other horses. Horses require other horses for security, comfort, and behavioural health. Horses need friends throughout their entire life, first their teaching mother, and then their teaching herd. Today’s domestic horse needs horse friends and human friends, although horses do retain the wherewithal to survive just fine without horsefolk. Horses need friends so greatly and constantly, that horses allow horsefolk to substitute as friends. This is possible because man shares a sociality with domestic horses. We speak their gesture language, and horses speak ours. We share a language of movement, and language described as kinetic empathy.
Domestic horse is no longer human prey, and has not been for thousands of years. Horse has been brought into the circle of humanity, along with a dozen or so other domesticates that share an adequate sociality with mankind to be allowed to develop a mutually beneficial relationship.

Horse and man have co-evolved together for thousands, if not tens of thousands of years. Each knows the other, well, and horses have proven to know the nature of people more consistently than people know the nature of horses. It is paramount that horsefolk appreciate the social and communicative nature of horses, and deal with horses in a fashion that is appropriate to their long-evolved social nature.



In addition to adequate and appropriate sociality and socialization, the importance of the need for near-constant motion is paramount to proper application equine behaviour. Locomotion is essential for horse health. In natural settings, horses move about grazing, playing, trekking, and variety of other movements as much a two-thirds of the time. Abundant movement provides constant connection and communication with the other horses in the herd, and as well, sustains the overall and physiologic functions of the horse. Plentiful locomotor activity facilitates behavioural expression and maintains physiologic health. An essential interdependence exists between horse health and locomotion. Horses evolved to be near-constant walkers and grazers. Horses did not evolve to be confined in stalls and stables, but rather evolved to live in open herd settings. Despite domestication and selective breeding for docility and captivity, horse health remains dependent on locomotion. Locomotion is inherent to grazing. Locomotion is inherent to digestion, to respiration, to metabolism, to hoof health and function, and to joint health. If horses are not allowed to move about freely and socialize with other familiar horses grazing and chewing as they evolved to do, they become metabolically vulnerable and subsequently troubled. Horses deprived of locomotion and constant forage ingestion develop strategies to maintain the motion and oral security they feel they need to survive. When horses are deprived of adequate and abundant locomotion, they develop strategies to keep themselves and their jaws moving, as is their essential and inherent nature. Horses deprived of friends, forage, and locomotion are at risk to develop stereotypies to provide themselves with the movement they need to survive.

The primary premise of equine behavioural health is this: in natural settings, horses walk and graze with other horses two thirds of the time. They take a step and graze, then another step or two grazing and moving along, always observing their surroundings, grazing while in touch with other members of the herd unless playing, occasionally dozing or sleeping, but only under the secure and established watch of others. Horses that are not afforded the opportunity to graze and walk much of the time take up with behaviours to replicate essential locomotion. When stabled, some of the horse's long- evolved survival behaviours become unwanted and unwelcome.

Horses require friends, forage, and locomotion to stay healthy and productive. Additionally, horses need clean air and abundant space for optimum health. In rural settings, these requirements are easy to fulfill. Open grasslands and steppes are the geography and environs from where the most recent predecessors of Equus caballus evolved. The further we remove horses from their social grazer of the plains preferences, the more health issues develop that require treatment and management by veterinarians and horsefolk.

Stabling, stalling, hospitalization and transport all deprive horses of their preferences for friends, forage, and locomotion. Although convenient for horsefolk, stabling is inconvenient for horses. Stabling limits the resources of friends, forage, and locomotion. Stabling creates bad air, and allows pathogens and parasites to travel easily between horses. When stabling is required, horses are best served to have their natural needs re-created in the stable. The air must be kept clean, and forage must be always available. Opportunities for movement and simulation of grazing with friends must be provided in abundance. Once our horses’ behavioural needs are understood, appreciated, and fulfilled, the learning and training can begin. Enrichment strategies re-create the needs of stabled horses. Horses deprived of friends, forage, and locomotion are not able to learn as well as appropriately socialized horses. Those strategies that best replicate the grazer of the plains scenario promote the best health, learning, and performance from horses.

Locomotion and socialization are essential for both horse health and healing. Husbandry, healing, and rehabilitation nearly always benefit from appropriately managed locomotion strategies that are constantly tailored to the horse's healing process. Locomotion is required not only for normal healing, but for normal digestion, respiration, hoof health, circulation, and all other physiologic functions of the horse. Stall rest is at the expense of many systems, especially the hoof and metabolic systems. Digestion and respiration are compromised by confinement and restriction of movement. Metabolic, digestive, circulatory, hoof health, musculoskeletal, and nervous, systems, as well as the all other systems and functions of the horse, are dependent upon adequate and appropriate locomotion for normal functioning and/or healing.

For horses that are hospitalized, paddocked, stabled, and corralled; active implementation and re-creation of the social pasture setting is required to optimize and maintain health and promote healing. Medical conditions are apt to deteriorate in the face of the deprivations of forage, friends, and locomotion created by stabling and hospitalization. Re-creation of a natural setting in the stall is the biggest challenge veterinarians face in maintaining the health of stabled horses.

Stalled horses not only heal poorly, they learn and train poorly. Locomotion, social, and forage deprivations create problems for horses. In addition to appropriate medical treatment, veterinarians and stable managers must creatively provide horses with abundant socialization, forage, and locomotion to maintain health and facilitate healing within the parameters of acceptable medical and surgical treatment. Restriction of locomotion to facilitate healing necessitates the implementation of enrichment strategies to simulate locomotion, including massage, passive flexion, and a wide variety of physical therapies.

Horses also heal horsefolk, and those horsefolk that implement these healing strategies often experience a sense of healing themselves, it seems. The human/horse bond runs deep. Domestication of the horse is a co-evolving evolutionary process. The human perspective is being shaped by the horse's perspective these days. Appreciation of the science of equine behavior and equitation is encouraged to support the renewed interest in equine medicine and welfare, and to facilitate the veterinarian’s role of providing horses with their essential needs.
