Exactly what kay said.. I think its a good idea and should be very rewarding to own a deaf dog, but in my opionion i would be scared.. I mean, what if you opened the door and the dog shot outside into the road, he has no way of knowing you say to come back, unless he is looking at you.. Im not trying to scare you away from the idea or anything because thats not what im doing at all.. I just would be scared..
