He does not know thast he is biting too hard. It is not aggression, he is just playing and was not left with his mom and siblings long enought to be taught how hard not to bite.
You can try yelping when he bites too hard, that worked for mine. If it doesn't work, then use your hand like a dogs mouth and bite him with a quick pinch on the shoulder.
One day I was carrying both my guys and one kept biting at my hand. since both hands were occupied, I snapped at him like his other would with my mouth, he quit instantly. |
