They are actually peaceful misunderstood puppy wuppy dogs - the Muslims of the dog world.
No that is being facetious, they are animals, the product of breeding and environment. Any dog or animal can be bred to vicious. The Russians bred, I think minks, one group bred to be very aggressive and the other to be very timid. With the aggressive group they could hardly get near the cages. All I’m saying is that individual people destroy individual lines within a breed, it is not that the breed is inherently bad.
