Little yap-dogs are a crap shoot too, I think. One of my daughters was bitten in the face by a babystitter's Yorkie and we were lucky her eyebrow took the worst of it, as it was very close to her eyeball. I was also bitten in the face as a middle schooler by a black/white Border Collie, which I thought were supposed to be relatively friendly dogs. I've gotten to where I don't truly trust any dog just on looks/breed alone. I've seen some mean-ass Labradors too, which isn't common but does happen.
