is it possible for a puppy to have parvo without running a temperature?

My 8 week retriever is still sick and is being tested for Parvo and other viruses, but he doesn't have a temperature, he has had the vomiting and other thins but no temperature?he has been in the vet since monday, stomach scans show nothing, he only had a temperature on saturday and this was gone by sunday, but he has been sick now for a week, parasites have also been ruled out, any other ideas what we should be getting him checked for?

it is, but not very likely, call your dogs vet and tell them what you just told all of us.Hope This Helps!

It is possible, though uncommon. A very common symptom of Parvo is bloody diarrhea, which may have an acrid smell. I hope the test results come back soon! Parvo needs to be treated immediately if there's going to be a good chance of survival!
