Why is my puppy passing live worms after deworming medicine?

Heartworm preventative medications also kill intestinal worms such as hookworms and roundworms, so it's not uncommon to see a puppy pass some worms in the stool after getting a dose of heartworm prevention. As long as Ginger is acting normal, this shouldn't be cause for concern. She will likely finish passing the worm the next time she has a bowel movement. You can take her outside for a potty break to see if she needs to go, or gently wipe her rear end with a warm washcloth to see if the worm will come out easily.

No, it would be highly unlikely to see worms in every stool. Worms only pass through the stool intermittently, just as they only shed their eggs intermittently. Be sure that the deworming medication that you purchased is appropriate for the type of worms that are present. If Diamond's worms resemble spaghetti, they are likely roundworms, whereas if they resemble grains of rice, they are likely tapeworms. Tapeworms can be a bit trickier to treat and will likely require prescription based dewormers from your vet. As fair warning, if Diamond has a large burden of worms, she may vomit or have diarrhea with worms present, but this is usually short-lived. I hope that all goes well!

What you are seeing are likely dead or dying intestinal parasites. It is common to see parasites in the stool after deworming. You may need to repeat the deworming in 2-3 weeks to kill any remaining parasites that were not developed at the time or the first deworming.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Hopefully seeing the worms pass in her stool means that the medications are working. I recommend rechecking a stool sample in 3-4 weeks to make sure there are no eggs present

Hello and thanks for using Petco Pet Education Center, formerly Petcoach! Parasite eggs are microscopic so I'm wondering if what you're seeing in the stool is actually eggs. It could be adult roundworms or even tapeworm eggs. It is not uncommon to see the adult roundworms as they are killed by the deworming process. If it is tapeworm eggs, you may need to end up treating for fleas (as this is how tapeworms are spread). The Dolpac should help treat for tapeworms and the praziquantel should be effective for giardia and roundworms. It is possible that you may end up needed to retreat but I suspect what you are seeing may be normal for the deworming process. Definitely take a fecal sample back to your veterinarian in about 3 weeks to ensure the infection is cleared. Also the prevent reinfection make sure to clean up your dogs feces from the yard. If at any time Echo seems to be acting ill or has diarrhea I would take her back to your veterinarian.

Hello there! If the worm wasn't moving, it was likely dead, and some worms do get excreted once they die from the dewormer instead of being resorbed into the body, especially if Skye had a lot of them. I would not give her more dewormer without the advice of a veterinarian at this point as they will likely deworm her again at her next appointment. Good luck, and I hope Skye grows up to be a healthy, happy young dog! :)

Congratulations on your new puppy. I have a dog named Hayden too! I suspect what you are seeing are roundworms. They are commonly passed in the stool after deworming, so you are correct that it just means that the medication is working. I have attached a handout below with more information on roundworms. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=476 Since we now know she had a roundworm infection, be sure to clean up after her each time she goes, so the yard does not get infected. I hope that was helpful. Thanks for using PetCoach.
