Why did my dog pass worms after deworming? Is it a good sign?

Congratulations on your new puppy! I would recommend that she sees veterinarian for a new puppy visit. She will have fecal testing and see if she needs a deworming medication in addition to the Interceptor. She will also be started on her initial vaccines. I suspect the Interceptor tablet you gave is working and killing the intestinal parasites. That is why you are seeing them come out in the stool. You will want to keep her on it each month for the heartworm prevention as well. I hope this information helps!

Interceptor does treat some intestinal parasites such as roundworms and hookworms, so it's possible that this may resolve the problem. If you don't see any improvement in his stool in the next 2-3 days, it would be best to take a fecal sample to your vet for testing - some types of intestinal parasites, such as tapeworms or coccidia, are not covered by Interceptor and would require a separate medication from your vet to treat.

Yes, it's very common to see the worms after giving the deworm medication. This type of deworm medication works by inhibiting the nerves in the worm. While this usually does kill the worm, they may be somewhat alive still when they are passed in the stool. The fact that the worm came out indicates that it is at-least debilitated. If this was Millie's first deworm tablet, then it's best to give another one (like drontal plus) in two weeks to make sure you get all the worms. I hope that helps.

This should start working very quickly, but you need to give him another dose in a month to make sure they are all gone. Tapeworms are passed in segments, and they are dead, but you should clean everything in your home to get rid of them.

Thank you for using Petco Pet Education Center, formerly Petcoach! HeartguardPlus has pyrantel as an ingredient, which kills adult and immature intestinal parasites. Depending on the stage of infection, it can take several days for all of the adult worms to die and be passed in the feces. It is normal to see different types of worms in the feces, as this product kills several types of worms, which are very common in puppies. If you notice that your puppy is continuing to have diarrhea after several days, I recommend bringing a stool sample from Blaze to your vet to determine which parasites are present. I hope this helps and wish you luck with your new puppy!

Just in case, make sure your veterinarian is confirming the presence of roundworms (tapeworms can sometimes be confused for roundworms). If tapeworms are present, Koda will need a special medication. The two most common reasons for persistent infection with roundworms are not yet clearing the infection he was born with (yes, they can be infected in uterus) or your yard is contaminated with roundworm eggs (one study showed roundworm eggs remained infective for 20 years). Continue with the routine dewormings and start him on a heartworm prevention like Interceptor. You should also alert your vet who may change the deworming schedule. Remember that these worms can also spread to humans so make sure to practice good hygiene.

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
