I have no idea either, tbh.
The puppy...she's super cute, but goddamn all she wants to do when she sees me is f***ing bite/nip at me. We've tried just about everything that's been recommended to us to get her to stop, and all it does is fuel her to keep doing it.
Are you a provider for her?
Who feeds her? Who walks her? Who does she sleep next to? Who does she go to when she’s hurt or something happens?
I’ve raised 7 dogs in my lifetime. I have 2 right now that just turned a year old. I believe in discipline especially in the first couple of years but also letting them know who is the hand that feeds them and takes care of them.
When puppies bite me, I let them bite and put my hand sideways to the back of their jaw on the sides of the mouth where there’s no teeth. They can’t clamp down. They quickly realize “oh shit I can’t bite him, he dominates me.”
Make them see you as God. Period.
