After deworming, when will my pet pass worms and will I see them?

Most puppies will stay on their normal pooping schedule unless the dewormer causes GI upset, in which case it could be anywhere from 1 hour to the next day. If there are worms in the intestines who are susceptible to the dewormer, you will likely see them passing out in the feces within 12 hours. Also keep in mind, that you may miss a low parasite burden and that not all worms are visible to the naked eye. I hope this helps to point you in the right direction. Please feel free to post any additional questions!

It could be they had worms previously and you didn't know it. It sometimes can take until there is a heavy infestation of worms for you to see them in vomit or feces. Typically only eggs are passed in the feces, and those eggs can be seen with a microscope, not the naked eye. You have to repeat the deworming treatment to kill all the worms. The first one treats the adults already present, while the second in two weeks will kill the ones that had not yet hatched at the time of the first treatment. Hopefully you will stop seeing dead worms in the next couple of days, but it means the treatment is working. Best of luck.

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!

Hello. Once the tapeworm has been killed by the wormer, the parasite is often digested ( it exerts a protective coating while alive ), & we usually do not see tapeworms passed in the stool. If it was a particularly heavy infestation, you may see some pass out, but this is not the norm. Any signs of tape segments should also disappear shortly. I like Profender, it is a good product, but I would follow label directions & reapply when recommended. Otherwise, once it wears off, your cat can pick up more tapeworms from hunting & from fleas ( make sure you are using a good flea preventative, too ).

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.

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
