Hi all, I have a 7 week old miniature pinscher. I feel 80% confident the dog is deaf. It is not responding to any words or commands. I cannot get its attention by snapping in its ears. The ONLY way I can get the dog to respond is by shaking a tin can of coins. The dog hears it, and can tell in which direction I am shaking it. I usually cannot wake it with any other sound than the cans in the tin. The Vet I took it to had nothing to say.
