I have read the AKC Dog Book about the history of the breed, white washed. Killing the other dog wasn’t mandatory but it certainly does happen. The killer instinct was what they were after, and they sure got it, in spades. Aggression against humans may not have been desired but is a by product in the dog that dog fighters bred for. Don’t try to tell me any differently, you just make yourself look foolish.
You will never find that I said the breed should be banned because I haven’t said that. I do think the tolerance of aggressive dogs should be zero.
