A couple of weeks ago I asked for advice as Amber was ripping us to shreds with her teeth! She is now 15 weeks and has calmed down lots but still has her moments, especially first thing in the morning when the excitement of seeing someone after a good night's sleep sends her into a frenzy of toe biting!
We found that shutting her out of the living area for a few minutes (until she had stopped whining) helped as shouting "No" just became pointless. She soon realised that the bad behaviour meant being away from the family and being good meant she got to stay.
Also now she responds well to "Leave it" - which could be anything from stealing shoes, biting or generally trying to chew anything she shouldn't - when she "leaves it" she gets a treat and food motivates her 99% of the time!
Good luck, it will pass eventually.
