Sentinel Spectrum Chewable for Dogs

Sentinel Spectrum is indicated for the prevention of heartworms, fleas, and intestinal worms. It kills the immature forms of heartworm and controls heartworm infections. Sentinel Spectrum also treats and controls various gastrointestinal worms including adult hookworms, roundworms, whipworms, and tapeworms. The tasty beef-flavored chew controls flea population by breaking the flea life cycle in both egg and larval stages. Sentinel Spectrum is safe for dogs and puppies above 6 weeks old.

Sentinel Spectrum - How it works?

Sentinel Spectrum is an effective broad-spectrum parasitic treatment. It contains three potent ingredients - Milbemycin Oxime, Lufenuron, and Praziquantel. Milbemycin oxime prevents heartworms and protects dogs against heartworm disease. Praziquantel eliminates different types of intestinal worms and Lufenuron restricts the growth of flea eggs and hence, controls flea population.

Kindly Note: Novartis is now acquired by Elanco. So, the manufacturer’s name on product packs may vary according to the available stock.
