You have a little girl who thinks you're playing with her when you're not

First of all she's a puppy and needs to learn when the game's over
Like Chance said
Yelp when you want her to stop or yell No! or No Bite! Loud enough where she stops dead whatever she's doing

Then without saying another word leave her where ever she is
Do Not scold her or tell her she's being bad
Your talking with her will make her think you're continuing to paly with her
