Pitbulls aside, anecdotally, if we're talking breed size I've found Pomeranians and Jack Russells to pose more danger than, say, collies, labs, Great Danes, Newfies, etc. but I guess now I'm the one generalising.

I think training and care are really the main factors. There are certainly cultural tendencies to apply certain training approaches to certain breeds, but I really do think this is mostly correlatory.
