One of the more popular animal trainer jobs is dog training. Dog trainers often specialize in one or more areas of training. Many dogs are actually working dogs and help herd other animals. Some dogs are trained to assist law enforcement and military personnel. These dogs are also trained to protect and attack when necessary. Others are guide dogs that are trained for the visually impaired or people with other disabilities. Other animal trainer jobs involve training horses to either race or perform in horse shows. Trained horses may compete in dressage, a series of tests to showcase the horse’s movements, including walking and trotting.
