Appreciation of the evolved nature and behavior of horses provides the foundation for the ethical veterinary care of equine athletes. The establishment of a veterinary patient client relationship (VCPR) is instrumental in providing ethical care for the competition horse. Ethical veterinary practice supports the horse’s long-term health and welfare interests while avoiding pharmaceutical intervention in the days before competition.

Horses evolved as social grazers of the plains, moving and grazing in a mutually connected and constantly communicative fashion on a near-constant basis. Contemproary equine health and prosperity remains dependent on providing an acceptable degree of this near-constant movement, foraging, and socialization. When horses are confined to fulfill convenience and performance interests, the horse’s natural preferences need be re-created to a suitable degree to avoid exceeding the adaptability of the horse. As the adaptability of the horse is exceeded, welfare is dimished and the need for medical intervention to remedy behavioral, health, and soundness deficiencies is intensified. Contemporary practices regularly exceed the competition horse’s adaptability, resulting in the need for extensive veterinary intervention to sustain health and competitiveness.[1]

The more medical care and pharmaceutical intervention required to sustain any population of animals the lower the population’s welfare.[2] Ethical veterinary care supports the horse’s best welfare interests, as well as the safety of the horse’s riders and drivers. Medical intervention of the equine athlete should be avoided in the days and hours before competition, as pre-competition medication is associated with increased vulnerability and diminished welfare.[3] To properly support the health and welfare of equine athletes, the practitioner must be familiar with their patients both inherently and individually. Socialization, constant foraging, and abundant daily locomotion are the long-evolved requirements to promote and sustain optimal soundness, behavioural health, performance, and healing in competition horses.

Healthy horses function and perform more consistently and predicatbly in an unmedicated state. Contemporary pre-competition medication practices remove the horse’s ability to protect their health and sustain soundness by masking pain and suppressing symptomology and are therefor heavily regulated. Horses who require medication to alleviate medical conditions in order to compete are rendered vulnerable to injury and physical and behavioural dysfunction imperiling the safety of both horse and horseperson. Horses requiring medication to compete are often not fit to compete safely. Horses and horsefolk are best served to compete free of short-term pre-competition pharmaceutical influence. Infirmities require appropriate medical care and rehabilition before competition is considered and resumed, rather than pre-competition medication to allay active medical problems. The equine practitioner should focus on post-performance evaluations and necessary therapies to sustain horse health on a enduring basis. An emphasis on fulfilling the medical, physical, and behavioural needs of the horse to prepare for the future competitions is the essence of ethical veterinary care of the competition horse. Pre-competition medication practices that replace or supplant appropriate health care are not in accord AVMA Principles of Veterinary Ethics.[4]

For human entertainment, convenience, and revenue, horses are bred, isolated, stabled, conditioned and medicated to perform competitively. Comtemporary pre-competition medication practices are often at the expense of the horse’s health, safety, and welfare. Many current medication practices violate the AVMA Principles of Veterinary Ethics, specifically the clause that states a veterinarian shall provide veterinary medical care under the terms of a veterinarian-client-patient relationship (VCPR).

The AVMA Principles of Veterinary Ethics state that it is unethical for veterinarians to medicate horses without a VCPR. Pre-competition pharmaceutical interventions to remedy insufficient attention and preparation for the horse’s long-evolved health requirements are seldom in the best interest of the horse. The medical and pharmaceutical practices which support equine competitive pursuits should be designed to enhance the health and soundness of the horse on a long term basis and should not be intended to enhance performance.

Pre-competition pharmaceutical intervention has been demonstrated to have an overall negative affect on the health and welfare of competitive horse populations. Where horses are allowed to be permissevely medicated with an VCPR, injuries and catastrophic injuries are more prevalent. Horses are best served to be properly prepared to compete in a natural non-medicated state. Pharmaceutical intervention of the equine athlete should be avoided in the days before competition, as pharmaceutical intervention increases fragility. Intense and widespread pre-competition medication practices correlate with catstrophic injury vulnerability and diminished welfare.[5]

Equine athletic pursuits have historicaly been designed to measure the natural abililty of horses and the trainer’s ability to bring out the horses’ natural ability. Equine competition was originally designed to measure the natural ability of horses rather than their medicated ability.[6] It is important that the welfare and veterinary care of the horse take precedence over economic and human interests. Horses are born to socialize, communicate, locomote, and chew on a near-constant basis. For behavioral and physical integrity, these preferences need to be re-created to an acceptable degree in the competition stable. The ethical practice of veterinary medicine includes providing clients with the guidance to provide appropriate husbandry, nutrition, conditioning, medical management, and behavioural fulfillment of their equine athletes.

Equine welfare is best supported when horses are properly prepared, physically and mentally sound, and fit to perform in an unmedicated state. Physically or behaviourally impaired horses who require medication to compete should not compete until they are able to compete without pre-competition pharmaceutical intervention. All sensation, behaviour, and proprioception should remain physiologically normal. Sensation and cognitive awareness should not be suppressed with pre-competiton medication. This inludes the use of sedatives, stimulants, and pain relievers of all sorts. Treatments should not interefere with functional physiology.

Sound horses properly prepared for competition have little need for pre-competition medication. Unsound or behaviorally dysfunctional horses should be medically and behaviorally rehabilitated in a fashion that restores soundness before training and competition are resumed. Medication is for infirm horses, and infirm horses should not compete. Horses who require medication to compete become increasingly unfit to compete safely. Rather than therapeutic intent, many pre-competition medication practices have become performance enhancing at the expense health and welfare of horse and rider.

It has been demonstrated through time that horses and their riders are best served to compete medication free. As a result, anti-doping laws have been established by all agencies that regualte equine competition. Veterinarians are required by both ethics and law to follow these regulations. Horseracing statisitcs support that the less medication horses receive the more favorably and safely horses compete.[7]

The safety of the competition horse is dependent on unimpaired neurological functioning. Unimpaired sensation and cognitive ability are necessary for a horse to compete safely and fairly. Any medications or procedures which negate or diminish sensation and awareness in the horse impair the ability of the horse to compete safely.[8]

The safety, longevity, and durability of the equine patient should considered before short term pre-competition medical solutions are implemented. Familiarity of the patient includes familiarity with stabling, genetics, behavior, and husbandry of the patient. Many if not most medical conditions are a result of human mismanagement of equine stabling and conditioning. When the adaptability is exceeded, horses become unsound. Assessment of stabling conditions and athletic preparation practices are essential components of ethical equine care. Healing must be allowed to progress before competition and training are resumed. Client education is essential to create a husbandry situation conducive to equine healing. Restoration strategies that recreate the horse's social grazing and locomotion preferences facilitate and potentiate horse healing. Appropriate healing of many equine maladies is encouraged when the veterinarian provides appropriate medical care and carefully facilitates a scenario to provide the horse with appropriate physical rehabilitation and behavioural fulfillment. 

An 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 and move on a near-constant basis. Despite domestication and selective breeding for docility and captivity, horse health remains dependent on locomotion. Locomotion is inherent to digestion, to respiration, to metabolism, to hoof health and function, to joint health, and to behavioral fulfillment. 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 more stereotypies present in a population of equine athletes, the lower the welfare.

No longer is intense medical intervention prior to competetion a viable, ethical approach. It has been demonstrated that the more intensely horses are medicated to compete, the lower their welfare. The more medications required to sustain any population of animals, the further the deviation from their physical and behavioural needs. Rather than pre-race treatments, the ethical approach includes  performance of exensive post-competition examinations to address any weaknesses or unsoundness as a result of the performance.

Alternatives to precompetition medication with non steroidal anti-inflammatory medication and steroids include fulfillment of the horse’s long-evolved nature. Musculoskeletal soundness is attained by proper breeding, development, husbandry, and conditioning practices. Management of exercise induced pulmonary hemorrhage is achieved by specific daily development of the horse’s pulmonary and cardiac function. Unwelcome competition behaviors are best managed by fulfillment of the horse’s inherent behavioral needs, which include abundant daily socialization, locomotion, and nutrition.[9]

Ethical Horsemanship Favors the Horse

Hello learners,

The Science of Equine Behavior provides the Basis of Ethical Horsemanship

In consideration of the horse's nature and behavior, horsewomen and horsemen are obligated to provide horses an appropriate environment, unconstrained neonatal development, formation and fulfillment of the mare-foal bond, adequate nutrition, sufficient sociobehavioral circumstances, as well as training and horsemanship modalities based on the horse's innate perspectives and sensitivities.



By nature the horse is a precocious grazer of the plains, a social and herd animal, and flighty. Horsemanship and training are best accomplished through behavioral appreciation of the horse and facilitation of the horse's nature, rather than by force or coercion. Horses are best trained in a relaxed, calm state. Training that puts the horse into the flight or sympathetic state generated by fear and punishment while restricted by rigs or round pens is discouraged, and not in accordance with acceptable standards of animal training. Horsetraining and horse teaching methods are best based on scientific studies regarding the nature of the horse. Horses learn preferentially in a relaxed state from a calm experienced handler with adept communication skills.
Social behavior in natural feral settings is the 'natural' behavior that 'natural' horsemanship utilizes to appreciate the nature of the horse.
As to dominance, the science reveals that free-ranging horses form social hierarchies that are complex and rarely linear. Under natural open range conditions with adequate resources, horses seldom have the equivalent of an alpha individual because the roles of leadership and defense are more critical than domination. Dominance theory as a training modality is not only discouraged, but appears inappropriate. The formation of order in horse groups sustains collective welfare and enhances group survival, and reflects leadership rather than domination.[1] It is important veterinarians and students of equine behavior appreciate this science.
There is no alpha. Leadership is shared and alternated and variable and context dependent in established harems in natural settings. Dominance is rare, and certainly not prevalent. When present at all, it facilitates group protection and stability. Horses share leadership. Survival is herd based, rather than individual based. The lead mare leads the horses to water and grazing and resting places. She drinks first to make sure the water is safe, rather than because she dominantes the others. Students of equine behaviour appreciate shared leadership and herd stability. Horses seek competent leadership and are willing to accept competent leadership from humans.
The horse is special in retaining the ability to thrive in feral conditions independent of man. This allows us to study their true nature versus their stable nature and to apply that knowledge to their welfare as it pertains to training.
Horse retains the ability to survive without us, and survive well.
It behooves humankind to take care with horses. Sensitive horsefolk respect the 60 million year development of the horse's social behavior and development. They appreciate equine intelligence in regard to both training and husbandry, and what the future might hold.
Stabling is unnatural. Horses graze and walk together 60-70% of the time under natural circumstances, eating and moving from spot to spot independently but within a few meters of the next horse. Stable managers and horse owners should make every effort to accommodate or recreate these long-evolved herd grazing and life-in-motion preferences for proper physiological function and mental health.

Horses require other horses for proper health and prosperity. Horses prefer the constant companionship of other horses. A horse should seldom be kept alone. Horses being mixed with other horses and expected to share resources should be properly acclimated socially, and be given the required space to adjust to new herds without injury or undue stress. Every effort should be made to provide horses with the social benefit of appropriate companion horses through times of stress and illness.
Horsewomen and men need to appreciate the sensual nature of the horse, and understand the physiological needs of the horse. Horses prefer the open view. If they cannot be in physical contact with other horses, they need to see and smell other horses for proper behavioral functioning and responsiveness.
Water is the most important nutrient, and must be provided in consideration of equine behavioral preferences. Salt is the most important mineral, and should be provided daily in some fashion.
Grazing while moving is the preferred predominant equine activity. Horses did not evolve to metabolize grains and non-structured carbohydrates, or to remain stationary for even short periods of time. Serious metabolic issues develop when horses become sedentary grain eaters, and this lifestyle should not be imposed on horses.
Play and sleep are naturally occurring preferences that require accommodation however horses are housed or stabled, as sleep deprivation results in behavioral deterioration.
Horses are physiologically dependent on shared social grooming and sensual contact companionship. If stabling precludes these preferences from fulfillment, then every effort need be applied to replace or recreate these needs on a daily basis.
These behavioral considerations apply to horses in transport, and for those horses too, however unwanted, man is obligated to provide the proper environment, social functioning, nutrition, medical care, and exercise to sufficiently assure health and comfort.
As to performance, every care and precaution need be taken to avoid exceeding the adaptability of the horse. All of the horse's normal natural sensation should remain fully intact and functional without undue pharmaceutical influence. The horse's metabolic, physical, medical, and behavioral limitations are best be monitored by equine veterinary professionals on an intense comprehensive basis.
Professional veterinary societies and organizations are encouraged to provide education regarding equine behavior.

The Merging of Horses and Humans

 The Merging of Horses and Humans

Convergent social and communicative characteristics drew humans and horses together. In a sophisticated blending of group survival, a curious and social clade of horses merged into humankind's social structure ten to twenty thousand years ago or so. 

Our contemporary relationship with horses as companions and performers can be aptly appreciated through an understanding of the evolutionary processes that impelled horses and humans to merge together in the first place. The shared social traits and communication abilities continue to facilitate a mutually beneficial existence. These days horses sustain our dreams, and maintain man's connection with nature. To better understand the social sphere of horses is to better understand one's relationship with horses. Horsemanship remains slipping into a horse's social circle, to pair bond with the horse. 

The domestication process began tens of thousands of years ago when groups of horses and Neolithic people began sharing the grasslands of northern Eurasia. Before merging their groups together, horses and humans and dogs independently developed the communication and social skills to enhance group survival. Similar social goals facilitated a merging of the three species. Group survival became shared group survival. Dogs provided protection. Dogs and people cleared the grasslands of predators. Interested horses came closer, and became more tolerant, reaping the grazing safety. The hunting of horses shifted to the herding of horses, and in time this led to milking and stabling, breeding and riding, the most delightful animal pairing imaginable.

To grasp how man and horse societies may have merged long ago is to appreciatethe contemporary horse/rider relationship. To develop positive relationships with the horse, one must come into an awareness of the long evolved social nature of horses. Horsemanship merges human nature with the nature of the horse. The language of horsemanship allows horses and humans to achieve pairings that achieve far greater accomplishments than the sum of horse and rider would allow. 

The social nature of horses is one of constant awareness. Constant awareness is essential for group survival. The landscape must be surveyed as the group grazes collectively connected. The horseperson is best served to blend into the survival construct of the horse to achieve willing partnerships. Willing partnerships form the basis of the cooperative survival construct of the horse. Cooperative partnerships facilitate survival of horse and rider. Horses know to work together with other horses—provided they were taught to be a horse by other horses (appropriate socialization)—and can be taught to work together with a rider or handler.

Horses living in harems in natural settings remain constantly aware of all the other horses in the herd, behavior learned and taught within the herd. Socialization teaches survival behaviors to growing horses. Mankind capitalizes on the horse's survival behaviors to train and pair with horses. Successful horsetrainers train horses as the mare trains the foal. Horses are all about learning and awareness. Horses are born to learn. Horses are born to be aware of others to facilitate their learning. Horses learn to be horses from the mare and herd, the same learning and teaching emulated in horsetraining.

Awareness is essential for learning, and also for surveillance. Except for brief spells of sleep and play, horses constantly observe their surroundings for any unwelcome developments, such as the approach of predators. Predators include anything with which the horse is unfamiliar. All unfamiliar creatures, places, and things are considered suspect and possible dangers. Neophobia is the term used to describe this survival trait.

Most horses are innately fearful of all new things. This is normal and expected behavior. Horses constantly survey their surroundings with their stellar vision. They see by day or night, and nearly 360°. Eyes set high in their head, horses graze and gaze, they watch. The grazing nipping and chewing motion rotates their head enough to see behind them on a periodic basis. When not grazing or dozing, horses focus on watching. When dozing or sleeping, others horses watch for them. All horses need other horses for behavioral health. Foals raised by the mare and herd in a grazing setting develop into easily trainable animals. It is the herd of mares and foals that teaches thoroughbreds and other breeds to run at speed in close company, horseslong evolved flight strategy, flight in numbers. The mares and cohorts give growing horses the confidence to run by and through other horses at speed. Horses learn how to move from other horses. They learn how to see and graze, and perhaps most importantly, how to communicate with others as taught by other horses. This is socialization. Please appreciate the necessity of socialization in the development of normal equine behaviour, please.

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 behaviour, and portrays the educational approach to fulfill the health and welfare 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.
