If she is pooping out worms, that means that the dewormer is working. She may need to be dewormed several times due to the life cycle of the worms. I would also recommend having a fecal exam done at a veterinary clinic since not all dewormers kill all types of worms and parasites. Many pets can be infected with multiple types of worms at the same time.

Yes, it's normal to see dead worms coming out in her poop a few days after being dewormed - this means that the medication is working. As long as she is acting normal otherwise, this shouldn't be any cause for concern :)

Thanks for using Petco Pet Education Center, formerly Petcoach! That is not common 1 week after deworming. I would recommend you contact your veterinarian as they know which type of worms they were trying to treat and which medication they used but you will most likely have to have him reevaluated for another deworming treatment. It may be best to perform a fecal exam to check the specific type of parasite. Best of luck!
