It very well could be parvo. I suggest you get her to your vet ASAP for an exam and testing. You really need to know if it is parvo or not. Either way, your vet will help you determine the cause of the bloody diarrhea and give you treatment options. Then, once this diarrhea is cleared up you can get her started on her vaccines. Hope this helps. Best wishes.

    Oh no, poor Kitto! From one of the pictures, it looks as if there may be blood in the diarrhea, and I would be concerned that is a sign she has parvovirus. She isn't old enough to be fully vaccinated against parvo, and unfortunately parvo is quite contagious and deadly. The diarrhea could also be caused by intestinal worms, eating something rotten or toxic, a GI illness, or a foreign body. When a puppy has diarrhea longer than 24 hours, it's time to see a vet. I would take Kitto into a vet immediately so that the cause of her diarrhea can be diagnosed and treated. I hope this helps!
