I did the OUCH!!! thing too and it works great. She's teething so she can't really help it unless you make her aware it hurts you.

The growling part she just wants to play. I don't suggest you growl back at her you need to make sure she understand your the human and she's the dog. Why not teach her to play fetch. Have tiny treat in hand to start training her.

Remember at eight weeks she should still be learning from her mom. You are the caregiver now. She is very young and will probably not be able to understand what you want from her.

If you let her lose around the house she probably marked around the house and thinks that's her potty station. I suggest you buy a play pen or keep her in one room. Right after feeding take her outside and give her a treat for doing her necessities outside. When you see her looking and smelling around that's when she's looking for a spot to pee. Quickly take her outside and praise her. It might be cute since it's not a whole lot but the bigger they get the harder it is to train them. (You know I don't recommend she goes outside until she gets all her shots, peepads are great)
