Labs are generally more mellow. A lot of pit bull owners do, unfortunately, get them due to their inbred aggressive traits (not all pit bulls, I know there are some happy pit owners here). A person who wants an aggressive dog can train any breed to do something like this.
No doubt the pit bull put him up to it on a dare of some sort.
My dog got attacked by one lab in my neighborhood on a walk. Another time it chased me and my dog into some guys yard and was going to try and attack again till I found a stick. I have called animal control on them twice. There is golden retriever type dog in my neighborhood that goes nuts every time I walk past it. I am so thankful that it is getting older and can’t jump the fence it is behind.
Any breed?
I have never seen any news stories about a killer Bichon Frisé or Papillon.
