RAYNIN VALLAH

This is my puppy to a T. Except she takes treats gently. She just has a fascination with eating arms and ankles. When I try to stop her, she gets worse and bites harder and more frequently. I currently have scabs all over my forearm where she’s broken skin. Mind you, when she’s not in this mood, she’s a very gentle love-bug. My question is, would the same method of teaching a puppy to take treats gently also work to temper her bite on arms? If so, how would you recommend I start?
