I have a 2 month old Husky who is not obedient or disciplined , defiant and fights back and does not listen to NO, he also bites hard and leaves scratches. He also chases and barks at our cats, once also barked at a stranger. He does know a few commands, sit, turn around, lay down and hello. He has some food aggression as he acts insane and loses his mind when hungry, and barks and attacks. He is potty trained.
