My puppy has black stool, is weak, and has a bad stomach. What to do?

The clinical signs in combination with the age of your dog are causes for concern for the parvovirus. I would make sure she is tested for this immediately, because of how aggressive this disease process can be. It often requires significant hospitalization and therapy in order to make things right.

I would recommend taking Larbie to the vet ASAP. These symptoms don't fit with one disease process. I would be concerned about dehydration and inappropriate nutrition in a puppy showing signs of constipation. Tarry stools indicate blood in the GI tract, which could be a sign of Parvo viral infection or intestinal parasites. Weakness and paleness could be related to anemia, external parasites, internal parasites, infection, etc.

Poor Kuky. Given her anemia, I am very worried she may be suffering from a parasitic blood infection or gastrointestinal infection. Please work alongside your vet to ensure she is treated with the proper medications. Try to keep her as comfortable as possible and ensure she is eating and drinking.

It sounds like Euro is really sick. I would put a little Karo syrup or honey on his gums to ensure his blood sugar isn't too low. With his gums being white and his stool looks black I would strongly encourage to take him to your vet or local emergency clinic ASAP. He could be suffering for a GI bleed, a large number of intestinal parasites, a fatal virus like parvo or much more. With him being so small, he is likely dehydrated and Anemic. I hope this helps and he starts to feel better soon.

Black stool indicates digested blood from the upper GI tract (esophagus, stomach or upper small intestines). It could be that Daisy's dewormer killed a large burden of parasites in her stomach that contained blood, or that she has a significant GI ulcer. Daisy should see her vet to determine if there is a likelihood of active bleeding, a heavy burden of parasites in her stool, and then treat with any necessary antacids. Given her young age, this sign is more concerning and urgent in nature.

I recommend you take your puppies to the vet, along with a sample of their feces so the vet can run a fecal test if they so choose. Your puppies need regular deworming, as infestations of worms can make them very sick, and severe infections can be deadly. Worms in the stool (dead or alive) are cause for concern, and some types of worms can even be transmitted from dogs to humans and make them sick. Black stool may indicate blood, which requires treatment by your vet. The link below contains information on roundworms, and there are links to information on hookworms, whipworms and tapeworms within the body of the text. https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951364 . Good luck, and I hope your puppies feel better soon!

It sounds like Baymax is very sick. Blood in the stool is very concerning for severe inflammation and this can be due to many things ranging from parasites to parvovirus to toxin exposure. Anytime a pet is sick beyond 24 hours they need to see the veterinarian and I recommend to get her examined today and the stool tested. For most conditions, the prognosis is better with earlier treatment. I hope she starts feeling better quickly and please feel free to post any additional questions.
