Good afternoon, The new dog we got has started exhibiting dominant behavior with our resident dog. She will bite him in the mouth, ear and neck, stare at him, hump him, and all around try to be the boss.Jager is a very submissive dog by nature which doesn't help matters as I think Koko is taking advantage of him. This has caused much tension in the house and I am at a loss as to what to do. Do you have any advice on how to correct this behavior?
