We had a female growing up that had a litter and we kept one of the females. Well at about 6mo old she growled at my dad when he put her bowl down and then decided to move it he smacked the shit out of her and sent her to the other side of the garage. Well a week or two later he was out of town and I had to feed them, she did it to me before i even got the bowl on the ground and in return she got the same deal. She didnt do it again. Im with the others saying it probably should have been addressed the first time he did it.
