Lab With Parvo Wont Eat

I have a Lab mix around 2 years old. We got him Tuesday, October 11, 2011. He got his 5 way shot at the pound and the warden said that it could make him sick for 24-48 hours. The symptoms worsened, so Friday, October 14, 2011, we took him to the vet, and again Saturday. They told us that he is parvo positive, and they gave him shots and fluids. They sent us home with another shot and bag of fluids. We administered them as instructed, but he still will not eat anything and throws up any water he drinks. We have also been giving him pedialyte with a syringe in the corner of his mouth and that doesn't seem to be helping. Is there anything else we can try, or anywhere in the Massillon/Canton/Akron Ohio region that you would recommend for treatment?
