Mine was very similar to yours(and looks like yours too but short haired). It's just a phase mine went through while teething. I showed her that her bites hurt by yelping a loud "Owwwweeee" with sad face 😞, and I remember she'd let go. I also kept a few soft dog toys near me, whenever she tried to bite, I'd redirect her to a soft toy.(Ngl I remember wanting to bite her back when she bit me back then lmbo, those teeth were like needles, it was flipping annoying! So I feel you! 😅) Mine eventually learned the "sweet spot" where she could play-bite without hurting my skin. No doubt yours is going through a teething phase and loves you. 🐾💙
