Rat Terriers! Crazy, hyper, barks at everything, may be aggressive . . . (ok, at least the rat terriers I've had, supposedly they are supposed to be more "mellow" terriers according to some sources) but SO FREAKING CUTE!! My first dog, Ginger, was a "smooth fox terrier" from a local Iowa farm and she looked nothing like the AKC standard of a fox terrier, smooth or otherwise. She did look like a rat terrier though. So I have a definite weakness for ratties or rat terrier type dogs!
