Sentinel Heartworm Prevention for Dogs
Sentinel flavored tablets are tasty beef flavored chews for preventing heartworms. They are also used for killing and controlling fleas, roundworms, hookworms, whipworms, and tapeworms. The oral treatment saves the pet from several parasite borne diseases. It can be administered to all breeds of puppies and dogs.
How it works?
A Novartis / Elanco product, Sentinel are flavored tablets for preventing heartworm infection and for treating fleas and gastrointestinal worms. The beef flavored tablets contains Lufenuron, an Insect Development Inhibitor (IDI) that destroys the larval stages of heartworm, fleas and other parasites. It prevents re-infestation by killing the immature life stages of fleas and heartworms.
The powerful treatment remains active for four consecutive weeks. The tasty chews can be administered to puppies and adult dogs and is safe for pregnant female dogs.
Kindly note that as Novartis is now part of Elanco, the manufacturer’s name may differ on the product packs according to the stock availability.

You can start Sentinel treatment once the existing heartworm infection test is negative.
Choose the appropriate Sentinel pack out of four different packs categorized as per the weight of the pet. Refer the Dosage table for details.
Give the beef flavored oral treatment once a month along with the meal. The pet will take these tasty chews as a treat.
If not then break it into pieces and mix with the pet’s food. Make sure the pet finishes the meal to ensure ingestion of full dosage.
Repeat every month, preferably on the same date. Give the tablets to breeding dogs and pregnant females at the time of mating, prior to whelping and then repeat at every month.
