Help your horse stay in parasympathetic mode by helping him look for the answer and stay curious,” says Rashid. “If he’s worried, he’ll go to sympathetic mode where he can’t learn. Use just enough pressure and incentive to help him look for the answer, but not so much pressure he has to find a way out to protect himself.” The Path Ahead Under domestication the horse has diversified into three major types, based on size and build: draft horses, heavy-limbed and up to 20 hands (200 cm, or 80 inches) high; ponies, by convention horses under 14.2 hands (about 147 cm, or 58 inches) high; and light horses—the saddle or riding horses—which fall in the intermediate size range. Domestic horses tend to be nearsighted, less hardy than their ancestors, and often high-strung, especially Thoroughbreds, where intensive breeding has been focused upon speed to the exclusion of other qualities. The stomach is relatively small, and, since much vegetation must be ingested to maintain vital processes, foraging is almost constant under natural conditions. Domestic animals are fed several (at least three) times a day in quantities governed by the exertion of the horse. Senses Jim Masterson is the founder of the Masterson Method of equine bodywork that involves the horse’s input as a vital factor of the healing process. According to veterinarian Glennon Mays, wolf teeth helped the ancestors of horses chew twigs and leaves that formed the main part of their diet. However, since modern horses live on a grass-based diet, wolf teeth have become redundant in these animals.

So your horse might be more distressed than you know. Go easy on him during sensory deprivation—build up time in the indoor arena gradually, ask staff to minimize unpredictable outdoor noises, encourage relaxation, and praise calmness. Introduce scary places with a sniffing expedition on halter and lead, making the adventure as pleasant as possible. Add an experienced equine buddy, if necessary. Horses are easily dominated. The horse is a herd animal where a dominance hierarchy is always established. If done correctly, human dominance can easily be established during training without causing the horse to become excessively fearful.First described over 100 years ago, equine headshaking is still not well understood. UC Davis researchers confirmed that the trigeminal nerve, a large nerve that runs across the face, fires too often in affected horses, causing tingling, itching, or burning. It is seasonal in approximately 60% of cases, and signs can be triggered in response to wind, light, or increased exercise intensity. In severe cases, horses may experience self-inflicted trauma or interference with eating, leading to compromised welfare. Margaret Zancanella, a pleasure rider and seminar attendee, shares her new understanding of this concept. Mark Rashid showing off a horse’s brain, which weighs around 2.5 pounds. This dispels the myth that the horse’s brain is the size of a walnut. Photo by Crissi McDonald So there you have it, folks – a whirlwind tour of the horse brain. From their cognitive prowess to their emotional intelligence, horses are far more than just pasture ornaments. They're thinking, feeling beings with brains that are as intricate and fascinating as their gallops are majestic.

You can see some of that range of size in this 1909 photo of Baby Ruth, a small horse owned by C. W. Gillet, standing in front of Pink Parader, a large draft horse owned by Joseph Medill Patterson.

In humans and horses, when one sense is deprived of information, the brain pays more attention to input from other senses. So a deaf horse pays more attention to sights, and a blind horse pays more attention to sounds. The same compensation accounts for blind riders like Karen Law, who listens for directional cues while jumping mid-level cross-country and stadium courses, or Kristen Knouse who navigates flat classes by hearing hoofbeats echo off the rail. The sense organs have not changed, but the brain is now zeroing in on stimulation we usually ignore. Neurons in the auditory cortex strengthen in response to blindness, so that poorer vision creates better hearing. Training Indoors Because horses eat frequent, small meals instead of fewer large meals like humans, they don’t need a large amount of bile released at once.

This area of the brain is responsible for our reasoning and is something that makes humans completely unique. There is no one else who has as well-developed a prefrontal cortex as we have. With this part of the brain we can plan, we can compare, we can assess situations based on past experience. We can weigh the pros and cons of a situation, and we can link factors that do not necessarily occur simultaneously. It is impossible to identify why this has happened. The main factor is thought to be the domestication of horses. They just don’t need to think for themselves as much anymore! Another theory is that the breeding of horses to maintain characteristics has led to a gradual reduction in the size of the brain. However, the growth rate of hooves does vary somewhat depending on season, nutrition, age, exercise, and whether the horse wears shoes. A horse’s hearing is much keener than ours. They use their hearing for three primary functions: to detect sounds, to determine the location of the sound, and to provide sensory information that allows the horse to recognize the identity of these sources. Horses can hear low to very high frequency sound, in the range of 14 Hz to 25 kHz (human range = 20 Hz to 20 kHz). Horses’ ears can move 180 degrees using 10 different muscles (vs. 3 for the human ear) and are able to single out a specific area to listen to. This allows the horse to orient itself toward the sounds to be able to determine what is making the noise.

Although the space would, in fact, hold a small grapefruit, the cerebral hemisphere -- or "thinking" portion of the brain cavity is a lot smaller. Medical folks actually talk about the horse brain as having three sections:

The Path Ahead

Stamping: indicates a mild threat or protest (or they may be getting rid of insects or flies biting their legs). How to age a horse or tell a horse's age or to age a horse as it is called, we look at its teeth. Because a horses lifestyle means it is almost continually grazing its teeth naturally grow continually and are worn down. Because of this their teeth gradually change throughout his life which allows us to tell its age.
