I had one of those Its cute when they are little but it gets old real quick
When you want him to calm down hold him by the back of his neck ... Just hold the skin
This mimicks an older dog biting him to stop this won't hurt him and you'll be surprised how quick it works
The biting the other dogs .... This depends on how tolerant your older dogs are .... When they get tired believe me they will stop it but make sure he doesn't get nipped
Little pups need to know when you mean business so NO means no.... So try the nspe of the neck thing
If the doesn't work bundle him in a blanket ....but make sure he stops when you say no
