Did you know some German Shepherds are trained to be police dogs and attack people, and yet they are allowed to be kept as pets?
German Shepherds can be trained to be aggressive and pit-bulls can be trained to fight and be aggressive. But people also train German Shepherds to be kind and loving so people can train pit-bulls to be kind too.
Therefore if German Shepherds are allowed to be kept as pets, pit-bulls should be allowed to be kept as pets.
President Obama once said, "The simple fact is that dogs of any breed can be dangerous when they're intentionally or unintentionally raised to be aggressive."
Pit-bulls are not the only breed that can be dangerous.
Therefore people should be allowed to keep pit-bulls as long as they properly train them. As long as you take care of them, they won't become intentionally aggressive.
