My home state of Ohio just recently lifted the statewide breed ban on pit bulls. They took some of the "pit bull" dogs at the shelter and did DNA tests on them. Here's what they found:
Sad really. Sad that these dogs are being unjustly euthanized and that real pit bulls are being unjustly euthanized.
Now granted, I know that these DNA tests aren't accurate, but it just goes to show you how hard it is to pick out the true pit bulls. I'm a second/third year vet student and pit bull owner, and I can't even tell that those aren't true pits.
