My puppy has parvo

My almost 4-month old puppy has been diagnosed 3 days ago with parvo( he is vaccinated against parvo).But he doesn't have any of the simptoms.It all started with some vomiting 3 day ago, just white foam( it isn't the first time this has happened, as he likes to eat all he can get his paws on and he sometimes irritates his stomach).But what drove us to the vet is the fact that he was in contact with a puppy that died a week ago, from parvo.At first, the vet said it wasn't parvo, as he didn't have diarrhea.So he didn't test my puppy, just gave hime some treatment for dehydration, fever, vomiting, etc.But we tried another vet that would do the test and it came out positive.Since then, he's been getting daily shots, at first we fed him some boiled rice and mint tea with baking soda.But ever since then, the puking stopped, he still hasn't got diarrhea, he is more energetic and he has an appetite again.Should I thank God he beat the virus or should I be worried that there is worst to come?

You should take every day as it comes.   No virus presents exactly the same in any two dogs (think how differently two humans can get flu).  Different dogs have abilities to cope and different immunities - especially if vaccination is a factor.   Wih Parvo, vomiting is very much a symptom and can lead to dehydration, which is potentially a killer.  The same goes for diarrhoea and one tends to follow the other, but it does have to.  In my opinion, it is the presence of the virus causing Gasterointestinal Synptoms, not any particular symptom or severity of symptoms, that leads to a diagnosis of Parvo.

Ps The way that your puppy is now, sounds very reassuring to me.  However, if diarrhoea were to start then it could dehydrate him!

- so it would be worth a repeat vet visit to be assessed.  I have certainly seen Parvo cases get better after surprisingly little diarrhoea.
