Personally, I don't think your average pitbull is going to take fully trained K9 defending their owner. Now, a pitbull bred specifically to fight or w/e is a different story.
K9's are trained to injure/maim, but not kill. A fighting pitbull is essentially trained *just* to kill whatever is in front of it... We're talking about two different types of aggression at that point.

I guess that settles it
