Grooming, the art and science of pair-bonding with horses

Grooming
To pair bond and establish familiarity, one must brush their horse, often and regular. Massage is essential to maintain health in stabled horses, full body massage, por favor. Massage is diagnostic and therapeutic. Rub your stabled horses, please, rub them everywhere, do not forget to rub the coronary bands. Rub them before tacking up, rub to make sure they are sound. Rub, rub, rub, as rubbing creates winners. Forget the bute, and rub. 
 Brushing and grooming stimulate digestive and circulatory functions, as well as create social pair bonding between horse and horsefolker. Brushing enhances nutrition, circulation, and many physiological functions. If you are confused about rubbing, watch horses rub one another and watch horses rub themselves.
Stalled horses need a good hour or two of brushing a day to feel enriched. I have seen people train horses to ride by simply brushing them everywhere everyday. That is it, brushing, which apparently can involve and incorporate pressure and release and reward, creating the establishment of boundaries and yields. Mutual benificence. 

When in doubt with the training, brush, is what I learned from that little girl, and what I hope you to all learn from this unit.
When a horse becomes troubled, stop the training and brush and rub, please.

Troubled horses do not learn, while brushed horses learn well, oh yes. To brush your horse is to train your horse. Forget about showing your horse who is boss, show your horse who cares about them.
Brush your stabled horses, often, please. Rub and brush. Lunge them, too. The word lunge comes from lung, it seems, and to lunge is to enhance and maintain pulmonary health. The key to prevent bleeding (EIPH) in racehorses is abundant locomotion. Some believe drugs keep horses from bleeding, but the preferred method is abundant locomotion. Bleeding during a race prevented by abundant locomotion between races.
Notice how often horses self-groom their lower legs. Rub the legs all up and down before tacking up. Flex all the joints, please. Get the digital pulse, por favor.
Remember to rub your horse's fetlocks, pasterns, and coronets with your bare hands before and after riding each day for winning results. To know your horse, rub your horse.
Horses are physical beings. They need friendly touching, often. And clean: I dare proclaim horses are the cleanest creatures on the planet in open country.
Stabled horses, well, they get quite dirty when forced to live in a stall or stable. Open range horses seldom need bathed, but stabled horses may, so dirty and soiled a regularly unmaintained stall or small paddock is compared to the open range, where horses stay quite clean, but will sometimes show up very muddy or dirt-caked in insect season.
At racetracks, many horses are bathed daily, others less so. Many horses learn to enjoy the process, which involves extensive grooming and brushing and close physical contact. Other horses are quite aggravated by water, and many despise water squirted near their ears, eyes, and nose. 
Sometimes water is applied to cool horses off. The place to cool hot horses off, and the place they most accept water on the head, seems to be directly on their forehead, above the eyes, below the ears, straight on, right over the brain. This forehead area is where the most heat is dissipated in the least amount of surface area.
Horses in competitive training who get hot often come to appreciate head cooling, which is physiologically effective in lowering body temperature.
Watch the nozzle-squirting devices, and use a soft stream when habituating and desensitizing your horses to water. Hose the hot horse's body and up into the groin, as well. Get your horses habituated to water carefully over time, especially at first. 
Make your horse's first experience with water a good experience.
In some cultures, horses are not bathed with water so much as with brushing.
Rubbing a horse brings one into an awareness of the horse's soundness, health, and demeanor.
Rubbing simulates movement. If you cannot provide locomotion, you best get in there and rub. 
Stall-rested horses need rubbed and passively flexed for at least two hours a day to maintain health.
Friends, forage, locomotion, and rubbing.
Get in touch with your horses with your hands.
Cheers,
DrSid

Racehorse Heat

It’s Hot Out Here for a Horse
By SID GUSTAFSON
Horses don’t like heat. They evolved in cool, even sub-arctic climates and are generally poorly-suited to deal with hot, humid weather. Heat makes horses sweat. Horses dissipate 75 percent of excess heat by sweating. The remainder of the heat is blown off by respiration. High humidity reduces the horse’s ability to dissipate heat by sweating, making it more difficult to keep the body temperature normal.
Hydration and electrolyte balance are critical in the racing thoroughbred. Muscle, nervous, pulmonary, cardiac, and joint function are vulnerable to electrolyte imbalances. Most electrolyte imbalances in thoroughbreds are caused by excessive pre-race anxiety and perspiration (washing out), which can be exacerbated by the use of race-day Lasix.
Potassium is one of the critical electrolytes depleted by washing out, as are sodium and chloride. Lasix depletes calcium and magnesium. These electrolytes are all essential for proper nerve, muscle, and circulatory function, and they all must be balanced in relation to one another.
When electrolyte dysfunction begins, wobbliness and weakness ensue, stressing the musculoskeletal system. After electrolyte imbalance becomes marked, the syndrome can move into thermoregulatory dysfunction, and the core temperature of the horse becomes elevated, causing further and more serious consequences. Although, high temperatures cause exercising horses to sweat heavily to dissipate the internal heat, susceptibility to heat stress is not solely influenced by ambient temperature alone. Excitable temperaments are the biggest culprit. Calm horses can generally maintain a normal body temperature and minimize sweating utilizing their ability to remain quiet and relaxed. In hot weather, anxiety-riddled horses can become electrolyte imbalanced before the race begins.
Other factors that may make horses vulnerable to heat include failure to be acclimated to hot temperatures and high humidity, tendency to sweat, and withdrawal of drinking water before racing. Racehorses may lose to 10-20L of sweat in a one-mile race. Fluid loss thickens the blood, making it flow more slowly, delivering less needed oxygen as the race perseveres. Additionally, hot horses redistribute blood flow to the skin in attempt to cool the blood off. This combination results in less blood being available for critical racing muscles, resulting in muscle weakness and cramping, weakness that may become especially noticeable in the last half mile of a one and a half mile race.
