When I first moved out flatmate had one. I will never approach the floor mops ever again after that. They're cute when they're not awake or anywhere near you though.

A lot of the small fluffy breeds were originally bred as personal guard dogs - and they're still pretty good at it. Size notwithstanding. I think the real problem is the owners - people should be shot for purchasing a fluffy dog and not teaching it civilized manners. 'But its cuuuute' they say, not understanding that badly educated dogs are never cute no matter how fluffy they are.
