Yes, it is always the owner, not the dog. Cause these types of dogs are fighters by their nature. So if nobody trains them, they will attack anything moving at their site.

A pit bull bite my friend's mother on the face just couple months back. I am just piss off by those un-responsible people out there. The pit bull runner was trying to say my friend's mom was trying to play with the dog and she was the one caused the accident. Sh*t she was scare of dogs.
