The first step in managing equine aggression is identifying the cause, and if possible, removing it. Training and positive reinforcement to establish control over the horse are also used, along with desensitization and counterconditioning. Dominance-related aggression in horses is different from canine status-related aggression (also known as dominance aggression) in that it is not context-dependent. Environmental management is important as well; good management should include sufficient resources such as space, food, and water. Some horses are considered to have pathologic dominance aggression; they will attack other horses and people that are near them. These horses should be separated completely from other people or horses and have a poor prognosis.
