A monthly tasty chew given for the prevention and control of fleas, heartworm and intestinal worms in dogs.

Sentinel Spectrum is a multi-spectrum dewormer treatment for dogs. It prevents heartworm infection by killing immature form of heartworm.

This monthly dosage protects dogs from all the harmful intestinal worms, prevents heartworms and controls flea infestations -long-term.

How does it work?

Used in the prevention, control and treatment of various worm infections, Sentinel Spectrum is an excellent oral treatment for dogs. It contains milbemycin oxime, which disrupts worms’ nervous system, and cause death. It eliminates the immature stage of the heartworm larvae and the adult stage of hookworms, roundworms and whipworms. Sentinel Spectrum also contains lufenuron, an insect development inhibitor, which breaks the flea life cycle by inhibiting flea egg development.
