Most deworming products treat roundworms, hookworms and whipworms by paralyzing and killing the parasites; tapeworms are killed and broken up into smaller segments. Some intestinal worms, like hookworms and whipworms, are so small that you won't see any worms in your dog's stool at all.
How long after deworming a dog are the worms gone?
It can take as little as two hours for the worms to start dying off. However, in most cases, the process starts about 12 hours after administering the dewormer.
