BearDog would probably step on and squash it (in all seriousness I heard a sad story a while back about a chihuahua accidentally crushed and killed by the owner's other dog, a rottie).
I don't like the idea of miniaturised/handbag dogs tbh. And I don't think they're cute, though possibly I'm prejudiced because so many of the tiny dogs I've met have been horrible aggressive spoilt little things due to the owners treating them like toys or babies rather than actual dogs. I'm sure they can be fine if they're trained and socialised and given boundaries like any other dog, but so often that's not the case.
Actually I met one that could barely walk at all, it's leg muscles were so wasted from being carried around everywhere like a doll and never exercised. I just find the whole thing a bit distasteful really.
