Bring her to the vet and if he can't see her right away at least bring in a stool sample, probally a parasite that can be cleared up with antibiotics. The pumpkin worked great for us, not the canned stuff though, I roasted a whole pumpkin myself and pureed it, you can freeze little 2 oz. containers of the leftovers so that anytime she gets an upset tummy you have it to pull.
