Give your dog time to recover. Let it rest as much as it wants to. Don't keep trying to get it to play and make sure you leave its food and water down in case it decides he wants to eat. Good luck
My puppy is being treated for parvo and seems to be doing fine he is moving around and starting to drink a little water by himself. My question is how long will it take for him to start eating again and do they just start eating by himself just like he started drinking the water?
If it survived parvo it should be eating again as soon as its health starts to improve from the worst part of the illness. If it is not eating it will not get the nourishment it need to get healthy.
