That should be with any dog. Responsible breeders and rescue groups do screen to weed out the irresponsible owners, it's the backyard breeders looking to make a quick buck who sell to the irresponsible owners looking for an ego booster attack dog that are creating the problems. Unfortunately there are more backyard breeders than there are responsible breeders. There should be spay/neuter laws enforced and people who want to breed should be required to have a license (with a renewal fee), take classes and join a breed club.

Breed clubs have code of ethics that they expect their members to abide by. I've seen them and they require screening, spay/neuter of "pet quality" animals, proper care for their breeding animals, etc.

If it is only made harder to obtain Pit Bulls, then the scum bags who have ruined the breed will look to another.
