Should Animals Be Allowed To Have Pitbulls

Why shouldn’t we be allowed to have pit bulls? Pit bulls are actually extremely sweet depending on their owner. The dog I think is never to blame, the owner decides whether to teach the dog right and wrong. The owners are who make them mean and put them in dog fights, it's those people who make it harder for the sweet dogs. There are people with pet tigers and great Danes so why would one dog be excluded from a home with a good owner?
The state of California has made a law requiring pit bulls to be muzzled, which makes others think all pit bulls are dangerous. Pit bulls are I feel as if dogs shouldn’t be punished for the way they were taught. I think dogs should only be muzzled if they must be. No dog should be blamed for the way they look.
