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.
Does dewormer get rid of all worms?
Deworming medications (antihelmintics) are used to rid pets of intestinal worms. No single dewormer removes all types of worms, but many deworming products are effective for more than one type.
How long does it take for dewormer to get rid of all worms?
Most deworming treatments work in two to six hours after administration. Some medications will dissolve the worms while some will paralyze them. Paralyzed worms pass through the intestinal tract and are passed out in your puppy's poop.
Does dog dewormer work on all worms?
Although a broad-spectrum dewormer kills several different types of worms, certain single-celled microscopic parasites (protozoa), including coccidia and Giardia, cause symptoms similar to those caused by intestinal parasites, but they are not true worms. They require different prescription medications to treat them.
