Why did my dog die from parvo with no diarrhea and negative test?

Parvo tests, just like many other medical tests, are not 100% accurate, There are certain strains of the Parvovirus that will show up as negative 100% of the time. You must rely on the veterinarian's clinical experience with the disease and the dog's presentation to determine if Parvo is an appropriate diagnosis. Sounds like Blue should get some radiographs and blood work to see what else might be going on. Hope this makes sense.

I am so sorry about Elsa. If Elsa was a puppy and just had on vaccine she was not fully protected. I would be concerned about Parvovirus at that point. Other then that it could be hemorrhagic gastroenteritis or even a foreign boy obstruction. It could also had been a type of cancer. Without more information it is hard to say definitively what caused this without more information. You can always ask for a necropsy and your veterinarian can send sample out to the lab to try to get an answer. Thank you for using Petco Pet Education Center, formerly Petcoach.

First off, I'm sorry that you lost your dog so suddenly. Please accept my condolences for your loss. I'm only guessing here, but if he wasn't vaccinated, it could have been parvo that caused him to pass. It could also be that he had a foreign body, a severe GI illness, or if he was fed a raw diet, the bacteria from the raw diet could have made him extremely sick. Again, I'm sorry for your loss.

I am so sorry to hear about Darcy! This type of illness is so frustrating and I see it occasionally in my emergency practice. It could still be parvo, although false negatives are rare. It could be a toxin, anaphylactoid reaction, a parasite, HGE (hemorrhagic gastroenteritis), pancreatitis, a foreign body obstruction, or something else. The main thing with all of these is supportive care, so the iv fluids and are crucial. Certainly you are entitled (and even encouraged) to seek out a specialty center for a second opinion if Darcy is safe to transfer. Feel free to reach out to me for a consultation via the link below if you’d like to discuss more specifically Darcy’s bloodwork, X-rays, or treatment plan. Best of luck to you and Darcy!

Submit a stool sample to diagnose intestinal parasites. Supportive care (IV or subcutaneous fluids, anti-emetics, anti-diarrheals and parenteral nutrition) may be indicated until a diagnosis is reached or until your pup recovers.

If Paris tested positive for parvovirus it is likely that she did have parvovirus since we do not typically see a false positive on the test. While many dogs get very sick from parvovirus there are some dogs who develop mild clinical signs and others can even be asymptomatic for the disease. If she did not have a parvovirus test performed than it certainly could have been another disease - there are many causes of vomiting and bloody diarrhea in puppies ranging from intestinal parasites to dietary indiscretion (eating non-food items). I'm glad she's feeling better!

Hello. It is very unlikely that a 9-year-old dog can contract Parvo. But there is any number of conditions & diseases that can cause severe gastrointestinal upsets. I can not tell you if this is a fatal situation or not, all I can say is you need to stay in close communication with your veterinarian, reporting any unusual signs, or indications that your pet is not healing or doing well. Hopefully, with good treatment & medications, everyone will be feeling much better soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
