Are over-the-counter dog dewormers effective?
It's possible to treat roundworms with over-the-counter medicines such as pyrantel pamoate. Dogs need several doses spaced about two weeks apart to kill all the worms, because wormers can only kill the worms living in the dog's intestines and not the eggs or larvae. Repeated doses kill the new worms as they hatch.
