How old is she? Give her pedialyte through a suringe if she won't take it voluntarily. Maybe it's her tummy. Put some plain yogurt in a syringe it give it to her. There has to be more than 1 vet in your town. Get on
www.whitepages.com and call ALL the vets. I am sure SOMEONE can see her today. Otherwise, you'll need to take her to the emergency vet. Better safe than sorry.
