I have a 14 year old Flat Coated Retriever that has gone deaf. His bark had started to sound funny and we took him to the vet to see if he had a sore throat or something. His throat was fine, the problem was that he couldn't hear himself bark so sometimes it just didn't come out right. It is pretty normal if he is excited when he barks but sounds weird if its just a low bark. I know he barks a lot less since he lost his hearing. There were clues that it was happening but we didn't pick up on them. Latter on when we added them all up it became obvious. It doesn't seem to bother him a whole lot, he sleeps good.
