If it had been a domestic/feral dog, bodies would be laying everywhere... they kill for the thrill of the hunt only...
Btw, once you get 1 predator, guarantee more will follow... start reinforcing everything...
True most dogs kill just for the kill .all my pens are covered . I'm using 10x10x6 ft. dog kennels as grow outs and they're covered too . we have red tails Owls and eagles around here . don't take any chances.
