>>715274304The only reason dobermans don't chew up children as much as pitbulls is that dumb people buy pitbulls way more often. Lots of people think pitbulls are cute and call them "couch hippos" or whatever. The AKC doesn't recognize "pitbull" as a breed though, so if you google the most popular dogs they're never listed. But the vast majority of dogs you can find have the largest portion of "American Pit Bull Terrier" DNA in them, and it's like >80% of shelter dogs or something crazy like that. Pitbulls are the premier choice if you want a cheap-as-fuck big dog, which goes hand-in-hand with being a retard underestimating how much work it takes to raise a dog properly.
Most people buying a rottweiler, doberman, or german shepherd have to pay a lot of money for a properly bred puppy, so they tend to be better trained. This is on top of them just being less popular.
