For optimal parasite protection, Sentinel® Spectrum is formulated with three active ingredients that control and prevent fleas, heartworm and intestinal worms in dogs. These three active ingredients include Milbemycin oxime, praziquantel and lufenuron.
Milbemycine oxime prevents nerve transmission in invertebrates, which protects against heartworm, round worm, hookworm and whipworm. Praziquantel inflicts a muscle spasm in tapeworm, which is then attacked by enzymes and then disintegrated. Lufenuron regulates insect growth and disrupts the flea breeding cycle. Adult fleas that feed on an animal that has taken Sentinel Spectrum will produce eggs or larvae that do not make it to the adult stage, thus reducing the number of fleas.
A monthly, beef-flavored chew is an easy way to keep your pet healthy and parasite-free while also giving your pup a delicious reward.
All prescription items are NON-REFUNDABLE and NON-RETURNABLE.
