How Does a Dewormer Work?

Dewormers typically come in the form of tablets or chewable (oral medications), but there are liquid forms as well that are great for small dogs and puppies.

Most worms target the intestinal tract, and they include tapeworms, roundworms, hookworms, and whipworms. Heartworms are also common and affect the heart and arteries.

Tapeworms, roundworms, and hookworms target the stomach and intestine. The dewormer either dissolves the worm itself or paralyzes it and causes it to release its sucker and fall through the intestinal tract. The worm is excreted in the dog’s stool.

This treatment does not kill larvae living in the animal’s body, so the administration must continue until the larvae evolve into adults and are treated.

Heartworms infect the heart, lungs, and arteries. Various heartworm treatments are used to kill the adults and larvae, and heartworm preventative medicine is commonly given as part of a dog’s supplemental diet.

How Long Does It Take to Work?

Deworming time varies based on the severity of the infestation and the specific dewormer used. However, most dewormers can remove the infestation within 2-3 weeks.

How to Choose the Right Dewormer

The most important thing to do when looking for a dewormer is to find a medication that treats the specific type of worm your dog is infested with. For example, a medication that combats roundworms might not affect tapeworms or hookworms. Luckily, many dog dewormers treat multiple types of parasites.

It’s also imperative that you consult your veterinarian beforehand to correctly diagnose which worm is inhabiting your pup.

The right dewormer is one that treats the specific worm your dog is infected with and treats it efficiently and effectively.

Worms can cause nasty infections, but hopefully, this guide has given you everything you need to know to help your dog fight them. Don’t forget to contact a veterinarian to confirm which worm is inhabiting your dog before administering any treatment.
