I have one that was bad about tearing hogs up like that and I like to catch the hog and them not be chewed up so I clipped the four k9s off even with the other teeth a lot of older guys use to do this to their dogs and the one I have now will still be caught with the bulldogs just not able to shred the hog so bad.
That really doesn't sound as bad as I thought. Did you use bolt cutters?
