We also don't really have bite statistics. Almost every citation I see for the data that gets posted over and over again traces back to one of two sources. One was a paper done in the 90s which both asserts that its methodology is inadequate to infer breed related risk and inexplicably combines rottweilers and pitbulls into a single category, a point which never gets carried through into other discussions. The other is that dogsbite site which openly states it is an advocacy site seeking the elimination of pit bulls and frequently gets its "data" from facebook stalking victims of dog bites for pictures of dogs they spent time around recently and then attempting to guess the breed involved from said picture. This is some real clown level shit, especially if you've ever read reports about even veterinarians trying to guess the breeds of mixed dogs that are their patients.
