My Ginger is deaf and has been for a few years now (she's about to turn 20), and the only problem is when I am trying to rush down a hallway that she is strolling down. She can't hear me coming, and doesn't react to the vibrations of my movement either, so she leaps away and runs when she sees movement of me passing her out of the corner of her eye. Of course, most of the time I just wander along behind her so that I don't startle her, but mornings are rush time and I have no choice. I remember reading that the COTD can sense vibrations, so I wonder why Ginger does not.

Snoopy is incredibly lucky to have found a safe home. She wouldn't have heard a car or dog out there on her own.
