How to get my puppy to stop biting ME!?

[Verulam 2]

Wrong! At 8 weeks, he isn't teething. His puppy teeth will all be there now, and his adult set won't start to erupt until he's over 4 months.

Right now, he's mouthing. When he gets to this level of playing, end the contact. Stand up, say No Biting!, take him outside to empty, and put him where he sleeps. You need to imitate what would have happened in the nest - the one being attacked would probably yelp and, the important bit - turn away! Ending the contact. No hitting or shouting because with some boisterous puppies, that often brings them back for more. You could put a toy into his mouth, but for me, what works far better because dogs hate to be ignored, is ending the contact. And mean it.

The only 'normal' thing about this is puppies mouth. Some more than others. He has to learn there are consequences for unwanted behaviour.
