8 week old pup eating rocks

This is my beautiful Bonnie! I’m trying hard to potty train her, but in the 48 hours of having her it’s not going over too well. 😂

Basically, every time I take her out to pee, all she does is eat the rocks in my backyard, and rarely pees. And then I spiral thinking she will get sick from the rocks and watch her like a hawk. We will spend 20-30 minutes out there, and after we come back inside, she will pee on my rug.

Any and all advice is appreciated!
