Yes. I think the reason we don’t see more stats on them is that people deny they are wolfs (often 100%) and that he population is still small.
Pits are about 6% of the pet dog population but are responsible for about 65% of the killings in the US.
I’ve seen pictures of pit bulls that have been bred to have the coloration of rotties. There was an account of a rottie that went on a rampage on a bus that sounded like pit bull level injuries and some people suspiciously noted that the attacking rottie was said to be an adult weighing 40lbs. How many adult rotties weighing 40lbs are there? At the time, it was theorized that the dog was a pit bull with Rottie coloration> That’s why they are breeding the colors that way - to pass as other breeds. Pit bull owners freely lie about the breed of their dog and chide inquirers for not knowing the breed. I’ve seen an obvious pit bull dressed up in baby clothes with a baby pacifier and a pink bonnet. All this faking and lying etc. makes me wonder just how high the pit bull toll really is? Also, a rottweiler is so much bigger yet the pit bull kills more. I think the numbers are worse than they look. People cross pits with other breeds to pass them off as those other breeds when they need to. And all those pits released into the undeveloped areas are breeding freely as well.
And then there is the pitweiler. These are intentional crosses of pit bulls with rottweilers. I imagine that when the blood hits the wall, the owner claims this one is a rottwieler to avoid “Stigmatizing” the pit bull:
