I have read and tried everything in that article before, no luck.
My puppy hears me scream and gets more excited and bites even harder, growling...playing of course.
He seems to love biting me on any loose skin, like under my bicep while I am holding his toy in the air and not giving it to him. Oh boy does that hurt. He latches on like a piece of meat.
If I just leave my finger or whatever part of me he is biting still, he will get bored and stop. He gets off on me being in pain and trying to resist him.
He has been calming down lately, which is a good thing.
My past Maltese did the same thing as a puppy, and he grew out of it fine, never once showed his teeth or bit when he was grown up.
When my puppy gets out of hand I just pick him up in the air, then lay him down on his back and tell him "no more"
I then go get a Bill Jack peanut butter treat (his fav) and play time is over.
That is my experience, anyway
