Clearly, a vicious dobe in Shar Pei clothing. (Getting stealthy, those dobes are).
Actually, Shar Pei can be a vicious dog. And they are quite muscular and strong.
When I was a kid my step dad brought a pup back from South Carolina for us. This dog got nothing but the best treatment, no kind of teasing nothing.
Shortly after my brother was born, it just rapidly turned vicious.
One day my friend Jay came over, and one of Major’s gates was down, and Major chased him up on the the back of the sofa and trapped him there. This dog was real serious, it wanted blood.
We put him down after that incident.
Not defending the cops here. I would not ever try to cut a dog’s throat unless I had absolutely no other course of action at all, but don’t underestimate Shar Peis.
