I would recommend to test Luna again for Parvo but hopefully it is giardia, worms or bacterial over growth. Luna's vaccines do give her protection but she will need 1 more round done 2-4 weeks after the last vaccine. We finish the vaccine series at 4 months old as that is when the puppy's immune system is fully mature. Get her in to the vet today and have her checked. Best of luck. I hope this is helpful. Please feel free to post any additional questions.

    One other comment. Please make sure that all pets (dogs) who have been exposed get a booster parvo vaccination. Also, make sure that the other puppy is dewormed and vaccinated. The healthier the puppy, the healthier the immune system. Good luck

    Hello, and thanks for your question. If possible, I would keep your pups separated until both are symptom free for 2 weeks. If there is the possibility of parvovirus, that can continue to be shed in the stool several weeks after symptoms resolve. It is worth the inconvenience to taking the extra precaution, and give them a bit more time for their immune systems to respond to the most recent vaccination. Hope this helps and they both feel better soon!

    Many things can cause diarrhea from Parvo to parasites to bacterial over growth. Since she has not yet been vaccinated, the concern for Parvo is higher. This virus is very easy to spread and can even spread on your shoes. I recommend to have Nova seen by her veterinarian. Testing for Parvo is straight forward. Make sure she drinks lots of water and you can feed her boiled plain white meat chicken and boiled white rice. This is a bland diet and will decrease the work load on the cells. Parvo tends to progress quickly and the pups will get very lethargic, begin vomiting and the stool may become bloody. Treatment needs to be aggressive and begin early. Hopefully it’s something much less serious. I hope this is helpful and please feel free to post any additional questions.
