Witnessing the lock on that bite was something to see.
They are impressive.
It is important that pitbull owners know that their dog is capable of doing a lot of damage if it attacks.
That is the part of
"It is the owner, not the dog." that I agree with. Being an owner of a pitbull is much different than being the owner of most other breeds. As a pitbull owner, you may have to accept that no matter what you do, your dog is a danger to anyone outside of it's close family. And if that is the case, you need to keep control over your dog at all times when other people are around. Pitbulls can have this natural aggression towards other animals and/or people.
The people who mean the dog could be a sweet, love-everyone type of dog when they say
"It is the owner, not the dog." are often clueless. Yeah, some shitty owners can turn potentially sweet, loving dogs into asshole dogs. But some dogs have a natural aggression in their genes and absolutely nothing an owner does can get that dog to be sweet with strangers.
People like LettuceBrain who call themselves
"pitbull lovers" who think they can get every pitbull to be one of the sweet ones are the same people who will say
"He has never done anything like that before!!!" after their dog just killed another animal or took a chunk of flesh out of a human - or worse. There are always signs, but these people refuse to see them.
One thing I think is important to keep in mind is that if you come across a dog fight and a pitbull has a bite on another dog, you cannot just assume that the pitbull was the one who initiated it. Dog fights can happen, even if owners try to intervene in time, especially at dog parks. Often a pitbull will be blamed for a fight when he did not instigate it, but only defended himself. You should not blame a dog just because he won the fight.
