OK, we're all waiting for you Freeper defenders of these little doggies. I know you're out there.
These dogs and all other killer dog breads need to be banned.
Ever notice that this happens in the "cities"......as in inner cities?
Your average owner, meaning a good animal owner does not raise an animal as thus. If even a mild manner lab was considered the "big bad" and was raised as a mistreated fighter, the world would be hearing about the big, bad labs. Heck, even Yorkies for that matter.
But, its just a dog. This could happen with any breed. Like all the stories of Collies and Labs you read about. Right?
While breed matters a little, the most important factor by far is having an unneutered male dog.
If you fix your pit, he is going to be a fairly safe dog.
