sized miniature Guide Horses could be recognized as service animals. Features Miniature horses, with an average lifespan of thirty years, live much longer than dogs, and for those allergic to or frightened of dogs, a horse could make a good alternative. However, while a dog can adapt to many different home situations, a horse must live outdoors, requiring a shelter and room to move about when not on duty. Guide horse users may also find difficulty in transporting a miniature horse on limited-spaced public transportation, such as on buses or taxis. Some individuals also are concerned that a horse's powerful fight-or-flight instinct may lead it to have less predictable behavior than that of a guide dog. The Guide Horse Foundation suggest a house-trained guide horse should typically be able to control its bladder for six hours; however for transportation purposes it is suggested a practical estimate of four hours should be used. Training The process of training a guide horse is rigorous and takes about eight months for each horse. The Burlesons developed a training programme which began initially with the horse trained in basic lead work, in which the horse is taught to move at the speed that the handler commands and to navigate common obstacles. Next, the horse is trained in voice command recognition, and taught to respond to 23 voice commands. The horse is then taught to maneuver around both stationary and moving obstacles. After this, the horse is trained to signal to the handler when there is a step or ramp. Finally, the horse is housebroken, generally an easy process because of horses' natural aversion to depositing fecal waste indoors. Intelligent disobedience is a crucial part of the training of the guide horse, as the horse must be able to disregard any commands that would be unsafe to the horse and the handler. Suitability Horses normally live to be 25–35 years old. This is far longer than the lifespan of a dog (8–16 years, depending upon breed). On average, miniature horses may live one-third longer than large horses. Miniature horses chosen for assistance horse training weigh approximately . Eyesight is vital for a guide animal for blind users. Horses generally possess excellent vision. With eyes placed on the sides of their heads, they possess nearly 350 degree vision, are sensitive to motion in their field of vision, and often detect a potential hazard before their sighted
