my poor little dog he couldnt hear a thing he was very deaf all heard was ring but if you threw a stick he could plainly see he would pick it up and bring it back to me i couldnt call his name it would be no good it would be like talking to a piece of wood i took him to the vet to ask him for advice he was very pleasent and also very nice to my little dog he seemed to take a shine then he moved his fingers and began to make a sign my doggy seemed to know what he had to say just by making signs he could hear me everyday. now i can spell his name and he can come to me just by making signs that he can plainly see.
