I knew immediately when I saw the theme that I would be using our dog Burton as part of my response. Burton was rescued by Another Chance for English Setters, and has been with us for about 6 years. He came to us as a puppy. Burton is a deaf Field Setter. He knows an array of hand signs, and if you were a first time visitor to our house you would not know he was deaf until I told you. Sometimes I think he, and our other deaf dog, Piper--a border collie--"hear" better than our hearing dogs.
Deaf dogs are no trouble. They hold a stigma and there are many myths about them, but I would adopt a deaf dog in a heartbeat. They are easy to train and really watch your body language. Sometimes Burton knows what I'm going to do before I even do it.
Burton has one beautiful, crystal blue eye, and his brown eye has a patch of blue in it. His breeder was breeding for the white in his coat, often connected to deafness.
Unlike his left eye, he is never blue.
