Most dogs dont eat the ears off of your cattle
Most dogs don’t get the chance. Most figd likely can’t reach s cow’s ears. The dynamic between bovines and canines is ancient. If a dog gets them running, it has the advantage. Ever walked through a pasture of cows with a dog that was afraid of cows? It’ll try to keep you between itself and the cows. Cows will pick up on this, and approach you and the dog, then lower their heads and try to get the dog. It can be potentially dangerous.
