I recently got rescued a puppy who had just been through parvo, her mother died from the parvo when she was 4 1/2 weeks old. Ive had her for 4 days and I can barely get her to eat anything. The people I got her from were feeding her dog food gravy with a syringe and pedialiyte also through a syringe. When I brought her home I bought 4 different kinds of canned puppy food, but she wouldn't eat any of it unless I gave it to her through a syringe. And she wouldn't like the pedialiyte, only if I gave it to her in a syringe. She also had very dark yellow pee, and diarrhea. I also have cats, and they're cat food is kept in my room, and when I wasn't looking she would try to eat the cat food. I looked that up and people said its not good for dogs so I've been trying to keep her away from it. Yesterday I bought IAMs puppy food, and Tried to give it to her plain like the cat food but she wouldn't eat it, so I put it in warm milk and she wouldn't eat it, then I put some in the food in warm water and she ate it really fast. And she started licking water out of a plate, and some pedialiyte. Today I tried the warm water and food again, and she wouldn't eat it at all. But she was really trying to eat my blueberry muffin, which I didn't let her do because I know it'd give her diarrhea. So then I tried putting a little Cinnamon on the food and she started to eat it but then figured it out and just licked the Cinnamon off. She drank a little bit of water on her own, but likes to drink out of my cups more then her bowl.:/ She also just had diarrhea the last time I took her out a couple minutes ago. I don't know what to do. She is very thin. And she sleeps a lot. She has little to no muscle in her back legs so she falls over easily. She likes to follow me around though so I try take her outside to walk around for exercise but after a while she just gives up and lays down. I don't want answers that say take her to the vet I already know this but I just spent a lot of money getting my cat fixed and can't afford a vet visit right now. please help!

Justin,
You say the pup has just been through Parvo. Did you mean a course of therapy? Then he's been seen. What did the Vet or the Rescue people say?

As for his eating, he's still not weaned. Read through this website from ASPCA

ASPCA | Weaning

Pick up some Enfamil or Puppy milk to help him stay nourished while you find out what he will eat.
