If you think your puppy has parvo, you need to get him to the vet ASAP to get a positive diagnosis. If it IS parvo, he will have to stay at the vet to receive supportive care. It is EXTREMELY difficult to pull a puppy through parvo at home as they often need IV fluids to prevent them from becoming dehydrated.
Also, if you have other dogs, it is important to keep the puppy separate from them, something that you really cannot do at home. At the vet's the puppy can be put into isolation or in an area with other parvo dogs to keep the infection under control.
Gatorade is fine as long as the puppy is eating and drinking on his own, however if he gets sick to the point where he isn't eating OR drinking, Gatorade isn't going to do him any good at all. This is where IV fluids come in.
It's best not to mess with this at home if you want to give your puppy every chance of survival. Parvo is extremely deadly to puppies and the average pet owner just is not equipped to deal with it. Please take him to a vet, not only for a positive diagnosis but also to be sure he gets the proper care FOR that diagnosis. Please come back and let us know what the vet says.
