It is a shame he did not stay with mom and siblings long enough to learn how to play. I have a litter with no momma dog and people have asked me why not let them go early. But they still learn from each other so they will stay with me together til they are 12 weeks old. They learn how hard to bite and the consequences of going too far.
Since you already have your pup, sending him back for a few weeks is probably not an option. Try giving tiny little nips with your fingers behind the head in the fleshy neck area when he is too agressive or bites too hard. This is what the momma dog would do if he was still with her. She would use her teeth, but you can do the same thing with your fingers. Don't hurt, don't holler, just say "no" in a firm voice and give the little nip/pinch. Be consistent and hopefully it will help.
I agree about not using the crate as a time out place. |
