Another thing....

Call the vet, because, depending on the puppy's condition, if you give her food, you might "shock" her system.

I have no idea what's wrong with her, but there are cases where the internals get "sucked" together. If you feed her, she could... you know. Puppy no more.

Vet dude. Vet.

BTW: Don't even THINK about paying the vet's bill. That's your girlfriend's responsibility. Trust me dude, pay this time, pay for the rest of your life...
