I don't have a Cairn Terrier, just a big ol' Rottweiler. Well, actually he's not old, he's only 4 years old. My next door neighbor has a Cairn Terrier named Tubby. He's a cutey, but sometimes he can get annoying. There's a Cairn at one of the dog clubs I go to named Tartan. He's very well trained and he is such a sweety!
