yeah theres no difference in inflicted damage
damage is damage...
Before pit bulls were all the rage, it was Rotts. Before that Dobermans and German Shepards...
Gee, three German breeds. The Rott is a big dog, a Molosser breed, just like the pit bull. And could and did inflict a lot of damage. The German Shepard and Doberman, due to their size and shape of jaws, have more scissor like bites...but still inflict damage.
The problem is, while the pit bull was bred to be a fighting dog, it's not some mythical killing machine. It was created by man, so it is flawed, as all dogs are.
If you cut down on the backyard breeders, have the AKC help establish certain lines, and breed standards (which means that the breed is recognized by the AKC), the issues that arise may be cut down.
