This happens more than one would like to believe. If your dog isn't trained to defend your person or property, do not assume that they will. They will often join in with whoever seems to be winning the tussle. This is especially true if the owner has not established themselves as master and the dog believes itself to be equal or physically dominant. This becomes even more likely with a spastic and unpredictable breed like modern pitbull terriers. Although exceptions do exist, even well bred pitbulls are not well suited for guard duty.
