And this one isn't? I'm not familiar with either of these orgs, but I'm not really confident that the site you posted isn't either.
They mention "The following is a REAL dog bite study, unlike the bogus and inaccurate data promoted by Coleen Lynn at dogsbite.org."
yet there is no study linked.

Looks like nobody has any real current data, which is a shame. We welcome these animals in to our homes, we trust them with out kids. Seems it should be something that is kept track of, I for one want to know which breed is responsible for the most human deaths.
I said previously I wouldn't own a Pit Bull despite the ones of my family members are sweet dogs. I would never own an animal that could easily over power an adult. I'll stick to cats and ankle biters I can kick away if need be.
