My puppy's poop is black after deworming. Should I be worried?

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!

Poor Luna! I can definitely understand being worried - it's always scary to see blood or other abnormalities in your dog's stool. The good news is, if she is eating and drinking normally, active, and not vomiting, it's extremely unlikely that she would have parvo or any other serious illness - puppies with parvo are usually very lethargic, not eating, and vomiting frequently. So it doesn't sound like this is likely to be an issue with Luna :) There are lots of things that could cause a milky substance like this with some traces of blood. Colitis, or irritation in the large intestine, can sometimes cause mucus with streaks or flecks of blood to be seen in the stool. This could also occur due to eating something she shouldn't have, or with a minor intestinal infection of some kind. She could also potentially have an infection in her anal glands, which are two scent glands located on either side of the rectum. If she is acting normal apart from this, it's not likely to be an emergency - but if the problem continues, it would be best to call your regular vet or take Luna in for a recheck exam to make sure that everything is okay.

Black stool typically indicates the presence of digested blood, most commonly from parasites or ulceration of the stomach or intestines. If Selfie's diet contains a lot of bloody meat, this could explain the black stool. Otherwise, this is not a normal finding and should be addressed by a vet fairly urgently. Selfie may need deworming and antacid medications to protect her stomach. If she has an ulcer, these can progress and become quite severe if left untreated. I hope that all goes well!

Yes, I would be concerned. It could be the change in diet causing the blood in Snow's poop, it could be intestinal worms since she hasn't been dewormed yet, or it could be an illness. I'd take her into a vet today to get checked out. Best of luck.

Black stool and extreme weakness are concerning symptoms that are an emergency and require veterinary care, especially in a young puppy. It would be best to bring Aura into your vet immediately for an exam and treatment.

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.

Black stool could indicate blood in the stool. Vomiting, and black stool could be caused by parasites, change in diet, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body, or a mass/growth in the gastrointestinal tract. In the case of an unspayed female dog , pyometra (a potentially fatal infection of the uterus) is a possibility as well, and this is very concerning. Please have Cassie seen by a veterinarian as soon as possible, as vomiting and possible blood in the stool can lead to dehydration and anemia, and can be very dangerous if left untreated. I recommend taking in a fecal sample from Cassie to your vet as well, as that may aid them in making a diagnosis. Good luck, and I hope she feels better soon!
