There has been some very irresponsible breeding going on with this breed, it's not the breeds fault. These dogs are a fighting breed and attracts a lot of thugs, drug dealers and low lifes as owners who do not know how to train and control a dog, or don't even want to.
This is not the only breed that will attack people, neglect or abuse any dog and you have a potential "killer" too.
And you call this an argument against exterminating the breed?
