What’s Sentinel Spectrum for Dogs?

Sentinel Spectrum tablets are a potent formula to protect dogs from multiple parasites. Sentinel is an easy to administer oral treatment and comes in beef-flavored tablets. This is a highly effective heartworm preventative, which helps in preventing heartworm diseases in dogs by killing immature forms of heartworms in dogs. The tablets also treat intestinal worms like roundworms, hookworms, and whipworms. It also inhibits flea infestations and keeps dogs safe from fatal diseases. Sentinel is safe for all dog breeds and puppies over 4 weeks of age and weighing above 2lbs.

Here’s How Sentinel Spectrum Works

The three key ingredients that Sentinel Spectrum contains are Milbemycin Oxime, Lufenuron, and Praziquantel.

Milbemycin Oxime

Milbemycin Oxime works by destroying the worm’s nervous system. It effectively blocks the nerve impulses, which constrains the organs of the organism from receiving signals. This eventually leads to the death of organisms as they stop receiving the necessary stimulus to grow and develop. It erases the tissue stage of heartworm larvae as well as the adult stage of roundworm, hookworm, and whipworm.


Lufenuron is considered an insect development inhibitor and stops flea eggs and larvae from maturing. It breaks the flea life cycle by inhibiting egg development and controls flea infestations.


Praziquantel is used to treat worms in pets. It is an anthelmintic ingredient that works by causing several spasms and paralysis of the worms’ muscles. Some worms are then passed in the stool. However, you may not notice them since they are completely destroyed in the dog’s intestine.

It is because of the inherent activities of these three active ingredients that Sentinel Spectrum for dogs provides its exceptional protection against roundworms, hookworms, tapeworms, whipworms, heartworms, and fleas.
