Blergh. My girlfriend's Chihuahua and my cat have always played kind of rough with each other — the dog nips at the cat's face, the cat swats at the dog — but it seems to have gotten even rougher in the past few weeks. To be honest, I'm not that worried about the cat because he's big and furry, plus he has all of his claws and teeth. The dog, on the other hand, only really has her teeth, plus she is short-haired and practically has no hair on her belly. One of them is going to get an ear ripped off or worse and it probably won't be the cat.
