EB1657Identifying Abnormal Equine Behavior ... and vices

L.A. Lawrence, N.L. Gates, D.G. Bowers
 
Vices affect a horse's usefulness, dependability and health. These bad habits may be due to a variety of causes including fear, nervousness, excessive energy, viciousness, nutritional deficiencies or boredom. Once established, vices are difficult to eliminate. Some vices lead to physiological problems, while others may be dangerous to the horse and handler, destructive to property, or just a nuisance. For these reasons, it is important to be able to identify and avoid situations leading to the development of vices. Learn to identify the problems described in this publication. When purchasing a horse, have a veterinarian and an experienced horseman evaluate it. Have an experienced horseman help you when you attempt to treat most vices.
 
 

Aggressive Vices

Aggressive vices of horses are particularly dangerous because they can lead to injuries of the horse, its handler, and other horses. The best way to cure aggressive vices is to eliminate the cause of aggression, whether it is improper training, fear, or contact with other horses. For the bad tempered horse, aggression is usually treated with some form of punishment, which should immediately follow the aggressive action. Aggression is a vice that must be handled by an experienced horseman. In most cases youth or inexperienced owners should not keep an aggressive horse.

BEHAVIOR

DESCRIPTION

CAUSES
Biting Horse nips at people as they pass by or during handling. Boredom. Bad temperament and lack of discipline. Discomfort. Confinement and lack of exercise.
Charging Horse attacks attendants or passers-by. Bad temperament or overanxiety at meal times. Fear. Overly protective mares with foals. Hormone problems in mares. (May be temporary; consult your veterinarian.)
Crowding Horse squeezes handler against walls. Nervousness. Insufficient exercise. Hormone problems in mares. (May be temporary; consult your veterinarian.) A learned avoidance maneuver in undisciplined horses.
Fighting Dominant horse bites, kicks, or chases. Introduction of new horse.
Kicking Horse lifts hind feet forward and kicks back in a sideward motion. Fear. Maliciousness or lack of discipline. Aggressiveness toward other horses.
Rearing Horse strikes with front legs while standing on hind legs. Bad temperament. Fear or objection to restraint, medication, or other stimuli. Harsh bit. Learned avoidance maneuver if the horse rears regularly when asked to leave the barn area.
Striking Horse reaches for attendant with either or both front feet. Reflex action to painful stimuli. Common when animal experiences pain in any area in front of withers. Fear. Confinement. Bad temperament, lack of discipline, or contact with other horses.
 
 

Vices Due to Fear

Vices caused by fear may be the result of bad experiences in the past or insufficient training and experience are often overcome by conditioning the horse to the frightening stimulus. Rewarding the horse for appropriate behavior usually is enough to eliminate the vice. In other cases, the horse will overcome its fear as it matures.

BEHAVIOR

DESCRIPTION

CAUSES
Avoiding Clippers Horse tosses head, pulls halter, or displays aggression when clipping. Fear of clipper sound and vibrations.
Halter Pulling Horse pulls back when tied or panics when crosstied. Poor or inadequate training. Pain.
Evading Halter Horse runs away when approached or otherwise avoids being caught. Fear or mistrust of people. Anticipation of bad experience.
Shying or Spooking Horse bolts at loud sounds or edges away from objects. Fear and lack of experience, accentuated by tensing of rider. Nervous energy. Poor vision.
 
 

Performance-Related Vices

Vices that occur when the horse is performing may be due to a variety of conditions. Once again, eliminating the stimulus is the best way to eliminate the vice. It is important to diagnose the cause of the vices immediately because they may be caused by medical problems, lameness, or ill-fitting equipment. On the other hand, some performance vices are due to excitement and general disobedience. In these cases, proper training is essential to overcome the vice. Many of these vices can lead to serious injury of the rider. Retraining by a professional or obtaining a new horse are often the best options.

Metabolic Vices

Many vices are caused by improper nutrition and subsequently lead to loss of condition and poor performance. It is important to cure the horse of metabolic vices as soon as possible. Often this can be done by providing more roughage in the diet and offering free-choice minerals and salt. Parasite infestations may also predispose metabolic vices, so regular deworming programs are essential. Feeding the horse small meals will reduce boredom and improve digestive function. Feeding the daily ration in three or more feedings may be advantageous. This approach requires the horse to spend more time obtaining food, which leaves less time for displaying metabolic vices. Exercise and turn-out time in paddocks and on pastures will help many horses avoid developing vices.

BEHAVIOR

DESCRIPTION

CAUSES
Coprophagy or Dirt Eating Horse eats manure or dirt. This could lead to colic or gastrointestinal ulcers, and other digestive disorders. Normal in foals 2-5 weeks old, establishes bacteria in the digestive tract. However, if too much is consumed, causes problems. In mature horses, can be associated with a lack of roughage, protein or minerals. Parasites.
Cribbing Horse bites an object, flexes its neck, pulls back with its teeth, swallows air. This causes a release of endorphins which suppress pain and cause an euphoric feeling of well being. Cribbing leads to weight loss, poor performance gaseous colic, and excessive tooth wear. Boredom. May be imitation of other cribbers. Lack of exercise. Confinement.
Food Bolting Horse swallows food without chewing. This decreases nutrient absorption and sometimes causes choking. Excessive hunger. Desire to finish eating before herdmates chase horse away. Competition for feed. Not enough feeding space for number of horses. Failure to separate horses by size and temperment.
Mane and Tail Chewing Horse chews on herdmate's manes or tails causing an unsightly appearance. Can cause intestinal obstructions. Lack of roughage or minerals. Playfulness. Boredom.
Wood Chewing Horse chews on wood fences or stalls. Can cause impaction colic, tooth wear and fence damage. Lack of roughage, protein or minerals. Boredom. Parasites.
 
 

Stall Vices

Stall vices are most frequently due to boredom of confined horses and often develop into annoying habits. These vices can be eliminated in a number of ways: providing companions, hanging stall toys such as an empty milk jug or tether ball, or installing metal mirrors at eye level. Another method is to increase the number of feedings per day. The best solution is to turn the horse out in a paddock or exercise it more often.

BEHAVIOR

DESCRIPTION

CAUSES
Digging or Pawing Horse paws at floor, creating holes that could cause leg injuries. Anticipation of feed or turn-out. Nervousness.
Tail Rubbing Horse rubs its tail against fences, walls, or other objects. Parasites. Habit.
Stall Walking Horse continuously circles stall. Boredom. Excess energy.
Stall Weaving Horse shifts rhythmically from forefoot to forefoot, sometimes swinging head as well. Stall weaving can lead to weight loss, poor performance and weak tendons. Boredom. Excess energy.
Stall Kicking Horse kicks walls of stall. Boredom. Aggression. Lack of exercise.
