You mean these stats from a 32 your study of US and Canada from 1982 to 2009 that shows over 60% of dog attacks from from pitbulls? Here's a collections of yearly reported dog attacks.

These are just a few of dozens of studies and reports that have been done on dogs attacks and biology.
The Fifth Estate also has a good video with proponents of both sides. https://youtu.be/iFa8HOdegZA
I am surprised the first response I got was not an attack. The pro pit propaganda runs hard and encouraged pretty rabbid harassment. I don't blame people that don't know for defending pits. It's the ones that argue in bad faith and ignore obvious data that are the problem. There's a reason why pits, and only pits, need to be defended so aggressively. All it takes is just googling reports of actual dog attacks to see almost all of the reports involved a pit or pit mix. Hell all you have to do is Google pictures of pitbulls vs porcupines and then compare those to literally any other dog breed vs porcupines. Normal dogs take a hit and get deterred out of their natural survival and pain avoidance instincts. Pits just maul them harder till they all but kill themselves. That's what happens when you breed some poor animal to fight to the death against other animals. It's tragic what we have bred into these dogs and even more tragic that instead of taking responsibility for it and at least attempting to breed it out and/or restrict breeding, we double down and make more and more lies about them that get innocent people maimed and killed. Then when people try to point all this out they get harassed to no end.
