We call those "pig parts". Cooper loves them, but he loves just about anything.
Rachael, those are only sold in $10 bags here at our pet stores. But I guess if she doesn't like them, you could always take them to her daycare for the other moms and dads to try out on their pups. I usually pull out the bigger pieces and give them to Jane for her big dogs.
EDIT: I totally forgot to say how cute Hershey is!!! HERSHEY IS SO CUTE!!
