Recently, I was on a dog website ( I forget what it was called) and read this story about this girl who got an Australien Cattle dog from a breeder. When she got the puppy, she knew something was wrong...the puppy was just not listining ,and, at 6 monthes, still didn't know his name. She took the dog to a vet and was informed that the dog was deaf. Her parents ( she was only 12) wanted to get rid of the dog, but Carly ( the puppies owner) Wouldn't. She says that the dog was sooo affectionate but just didn't know how to do anything. She now has been now has worked with the dog for two years now, and the dog knows "sit", "stay" and "come" and is working on down. She does it all with motions. Could you imagine how hard this woul be to do?
