Equine Behavior, a primer

Horses began their journey through time 60 million years ago. Three million years ago the footsteps of man 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 man began the dance of domestication with horse, the horse who became 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. No truly wild horses remain, excepting perhaps the Przewalski, which has a different number of chromosomes than the horse, and is not thought to be horse's progenitor. To the best of our knowledge, all horses today are descended from tamed and 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. The horse of today is with us to stay, it seems, and can live with humans, or without them.

Today horsefolk remain enticed by horses and 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 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.

Equine Behaviour differs from the other horse pursuits as equine behavior is taught from the horse's perspective while the other disciplines are taught from the human perspective. Equine veterinary behaviourists understand that appreciation and sensitivity to all of our horses' evolved preferences results in optimum health and soundness, and therefore optimum performance. Behavior is a result of evolutionary development and selective breeding (nature). The genetics are shaped by the social environment, nutrition, neonatal and juvenile development and training (nurture). Equine behaviour is heavily influenced by socialization. Subsequently, behaviour is affected by the intensity and type of stabling and husbandry. Horses need to grow up to be horses as taught by horses to eventually lead behaviourally healthy lives. 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.

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, however here we shall explore the science of what our horses want and need from us, the science of equine behaviour. 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. 

A 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 behaviours to replicate essential locomotion. When stabled, some of the horse's long-evolved survival behaviours become unwanted and unwelcome. 

Away we graze, moving through our coursework as a herd of horses might graze open range, connectedly, in communication with one another, learning, forever learning.

Appreciating Horses; Equine Behavior and Applied Horsemanship

Appreciating Horses    

Equine Behavior is the basis for Horsemanship
Sid Gustafson DVM

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 is the preferred and 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 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.

Healing in Horses

Restorative healing in Equus caballus.

Restoration strategies that recreate the horse's social grazing preferences facilitate and potentiate horse healing. Appropriate healing of many equine maladies is encouraged when the veterinarian provides appropriate initial treatment and subsequently carefully facilitates a scenario to provide the horse with abundant forage, friendship, and locomotion. 

Grazing pasture in an open setting with other horses, when appropriately orchestrated, has the potential to provide the most profound and often the most cost-effective healing of musculoskeletal infirmities and injuries. For conditions allowed to progress to lameness, time is required, often months. When musculoskeletal conditions are detected early, before lameness ensues, short term rest and restorative strategies encourage solid healing (days to weeks). Both long and short term healing are enhanced when the horse is content with the forage, friendship, and locomotion resources. Avoid unnecessary restrictions to locomotion whenever feasible.

The earlier inflammation is detected, the shorter the time period is required to heal. Healing in a social-grazing setting is a long-evolved trait of the horse. Horses acclimated to herd and pasture settings during their development respond best to restorative healing. 

Horsefolk need to take special care not to exceed the horse's adaptability regarding stabling and healing. 

Horses require a sense of comfort and security for physical and mental restoration (and maintenance). An adequate social grazing environment, or appropriate facsimile thereof, often provides the most comfort to the most horses. Horses provided with adequate socialization throughout their upbringing are most responsive to these strategies. For horses, comfort and security come from friendship, forage, and, most-critically, a near-constant casual locomotion. Young horses and newborns learn to be horses from the dam and herd, and foals are best served to develop with horses in an appropriate grazing environment, as well. Horses learn to socialize, communicate, graze, locomote, run at speed in close company, play, smell, balance, move, and compete from their mother along with the herd members.

Corral or stall rest is counterproductive to healing, as it deprives horses of all three healing essentials. Horses heal efficiently in a social grazing setting, not one of isolation and deprivation. To a horse, restoration, from the word rest, ideally implies grazing open country in a herd setting with abundant environmental resources; appropriate grasslands to graze and walk, salt, and appropriately placed clean water. The properly managed social grazing setting with the open view is the environment in which horses evolved to thrive and heal.

Healthy physical and mental development are best actualized in a social grazing environment. Neonates rely on their dam for critical early learning processes, including sensual development, locomotion, and early mobility.  The development of agility, coordination and athleticism in early life is critical to subsequent mental health and soundness. Abundant social contact, grooming, sleep, play, athletic development, and social bonding occurs during early herd life. Horses rely on constant contact and frequent interactions with other horses for healthy mental and physical development. 

Opportunities for the abundant expression of normal equine behavior and motion promotes healing. 

Unfortunately, healing opportunities of this sort are not available everywhere, especially in the more urban equestrian settings. Space and grazing limitations restrict healing opportunities. In these scenarios, the horse's preferences have to recreated with carefully designed and implemented ENRICHMENT strategies that provide some fashion of near constant forage ingestion that allow oral and physical and movement and motion. Stabling scenarios often restrict social expression and sensual contact. Horses are sensitive to these deprivations which results in stress, which complicates and delays healing. 

LOCOMOTION is essential for both horse health and healing. 

Husbandry, healing, and rehabilitation nearly always benefit from appropriately managed and free choice 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 necessary to maintain health and promote healing. The absence of abundant forage, friends, and locomotion is detrimental to a stabled or hospitalized horse's health, if not welfare. Medical conditions are apt to deteriorate in the face of the deprivations created by stabling and hospitalization. 

Stalled horses heal poorly. 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. 

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 a welcome change for the horse after centuries of considerable subjugation.

Understanding Horses

Equine Behavior Statement
Revised and Expanded

Sid Gustafson DVM

In consideration of the horse’s nature and behavior horsewomen and horsemen are obligated to provide horses an appropriate environment, proper nutrition, sufficient sociobehavioral circumstances, as well as ethical training and horsemanship modalities. By nature the horse is a grazer of the plains, a social and herd animal, and flighty. Horsemanship and training are best accomplished through behavioral understanding of the horse and facilitation of the horse’s nature, rather than by force or coercion.

Contemporary Horsemanship

Contemporary Horsemanship Pursuits


The centaur portrays something significant about our horsemanship desires. That primal mythological being displays our metaphoric ideal; head, arms, and torso of horseman or horsewoman blending gracefully into the body and legs of horse; Equus sapien. Those who ride horses understand this conceit clearly; to be the horse, to become the horse. Sophisticated Thessalonian Greek tribesman imagined and mythologized this manhorse creature, a cultural reflection of their emotional and physical blending with the species. The centaur expresses pastoral man’s exalted and cherished association with the horse. The symbol defines the willing partnership many contemporary horsemen seek. This book is intended to encourage people to refine their relationship with horses.
Centaur passion is expressed today as natural horsemanship, a renewed manifestation of our desire to connect with horse in a willing and conciliatory partnership. More than ever, or ever in recent memory, people seek unity with their horses, partnerships based on understanding and trust rather than relationships that are a result of dominance or coercion. Horsemen hope their horse engages in their wishes happily and readily⎯dependably, consistently, and reliably⎯wherever and whenever they ride together. A willing partnership based on time, trust ,and understanding is a high hope indeed, but a hope that has reached its true promise in many horse/man pairings through time.
The ideal connection facilitates empowerment from the horse, a controlled extension of our selves, a naturally manifested power that can make one delirious. After a century of widening disconnection, America’s horse culture is attempting to renew and refine the relationship that has bonded mankind to horses for millennia. Horsemen continue to seek a connectivity of their minds to the horse’s body as horsemen always have.
The horsemanship ideal reigns in America as it has reigned through time: that the rider’s thought becomes the horse’s action, the centaur effect, control of the horse’s feet, becoming one with the horse. Modern horsemen report that horse/man relationships approach this ideal with regularity. The nature of the horse, however, is such that the regularity remains uncertain. The horse retains the power to have the last word in this language of horsemanship we explore. The horseman’s goal remains to have a say in all the horse’s actions. A resurgence of conciliatory training methods has emerged offering horsemen/women a trusting and reliable relationship with their horse that is not forced or coerced, a relationship based on mutual respect and understanding.
