Ok for a few days I have been worried about TinkerBelles hearing. I whistle at my pups and Dodge turns but TinkerBelle doesn't seem to hear me.Sometimes she will be playing on the floor and i whistle and it's as if she can't hear me she just continues to play. Can it just be her age or could she be deaf? I am really worried does the vet have some kind of way to know if a pup is deaf? Oh my poor baby hope she isn't deaf but more than likely I think she really is.
