I've seen people turn Siamese cats into psychos...look at the reputation they have now.
The pit bull owner in our hood IS a moron...he whips the animal across the head with the leash whenever it doesn't 'toe the line'. I'm not sure why he is beating on the animal, but that is precisely WHY everyone is nervous. That dog is going to snap; sooner or later.
Hopefully it’ll turn on the owner, the evil, dog beating bastard.
