Our dog is losing her hearing, I think. It doesn't seem to be a big deal to her, and I have to admit life is easier when deliveries can come without even waking her up. She can still hear if I yell that dinner's ready, but she no longer comes scrambling when I open a can or dry food hits the dish. I get to surprise her now. It's helped our relationship, if anything.
@ttscoff when I met my wife long ago in Texas she had a dog that didn’t hear very well because he had caught the car and had his head run over or something. His name was barracuda a perfect name for a dog who kind of moved around the floor (he was very short), like a fish on the bottom of a river. He paid good attention, visually of course.
