Caring for a Puppy with Diarrhea?

Yesterday my puppy of 8 weeks had thrown up everywhere and had diarrhea (yellow, watery), as well. She did not want to eat and was really tired. She also was on pain medication and some medication for worms. I called the vet immediately and they told me to bring her in as quick as possible.

The vet tested for parvo and it came back negative. I also had her on a barf diet (raw food) which I had my previous dog on it as well and she loved it and was really healthy. I had started my puppy with some raw chicken wings and she ate them perfectly fine. The vet told me to begin with raw when she is older because she is so young.

Though the test was negative for parvo the vet said there is a big chance of her having parvo. I had a blood count done, the results being mild and some fluids run into her. We left her at the vet for a bit and when we returned to pick her up the vet was worried because she was really depressed and still had diarrhea.

We brought home some fluids (a home kit) to keep fluids inside her system. As soon as we were home she was happy and wanted to play. She can drink water on her own and we gave her tiny amounts of boiled chicken with no skin and some rice (no flavorings to both). She ate it all. She still has diarrhea, but she is active. We are giving her some Pedialyte and water at all times. She has a bit of a runny nose and a little bit of sneezing. I was wondering whether the raw food was too early to give her or she has a cold of some sort. Or maybe the full effects of parvo have not hit. The vet also said there could be a chance of having distemper. Please help.
