Sentinel Spectrum Chews – Broad-Spectrum Treatment for Dogs
Sentinel Spectrum Chews for Dogs is a broad-spectrum oral treatment that has been trusted for protecting young and adult dogs for over a decade. With just one dose per month, it safeguards against as many as six types of parasites. A single chew keeps your furry friend safe from fleas, heartworm disease, and all four common intestinal worms that can affect dogs.
Featuring a unique combination of three active ingredients (lufenuron, milbemycin oxime, and praziquantel), Sentinel Spectrum protects your dog from the parasites you may not see. If your dog does not tolerate topical treatments, Sentinel Spectrum flea and worm treatment is an excellent option.

Sentinel Spectrum Chews are a broad-spectrum oral treatment for dogs that protects against six types of parasites. With just one chew per month, it safeguards your dog from fleas, heartworm disease, and all four common intestinal worms. The chew contains three active ingredients: lufenuron, milbemycin oxime, and praziquantel.
Lufenuron prevents flea eggs from developing, breaking the flea life cycle and controlling flea populations. Milbemycin oxime kills heartworm larvae and adult stages of hookworm, roundworm, and whipworm. Praziquantel targets tapeworms, causing them to break down and be expelled from the dog’s body. Sentinel Spectrum has been proven effective against heartworm infection when given monthly over six consecutive months.
How to Use Sentinel Spectrum Chews?
- Weigh your dog to select the correct chew strength.
- Start treatment at any time of the year.
- Give the chew immediately after or with food for better absorption.

- For heartworm prevention, start monthly dosing within one month of first seasonal mosquito exposure and continue until at least six months after the last exposure.
