I've seen that little dog on TV! It looked even smaller then. I wouldn't want to have a dog that small, it would be a lot of work (trying not to step on it and all). It kind of makes me sick that they've bred a dog this small, though...
why not just buy a gerbil? They're cheap and would probably live longer and have a better temperment. (nothing against yorkies but people going for worlds largest and smallest records don't tend to care about temperment )
