The main difference between Dog A.I.D. and many other assistance dog groups is that the physically disabled owner learns how to train their own pet dog. Generally all the training is carried out by the owner with supervision from a specially trained instructor.
Dog A.I.D. training is designed to give a measure of independence and provide owners with the knowledge to train other tasks. This allows them to adapt the training to their own needs with an instructor, who is able to give advice as required.
