I and my girlfriend are very fond of my Cocker Spaniel, she is eight years old. I have always treated her with Sentinel from starting when she was just a puppy. It works perfectly in preventing heartworm disease without any side effects.

Sentinel Spectrum for Dogs - Flea, Heartworm and Wormer Treatment Control

Sentinel Spectrum is a multi-spectrum dewormer treatment for dogs. It prevents heartworm infection by killing immature form of heartworm. The oral treatment controls adult hookworms, and removes and prevents roundworms, tapeworms, and whipworms. It provides long-term protection and controls flea infestations and flea allergy dermatitis in dogs by preventing the development of flea eggs and larvae. *Does not kill adult fleas currently on the dog. 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. It prevents flea eggs from hatching and thus prevents and controls flea infestation by breaking the flea life cycle. Does not kill existing adult fleas on the dog.

  • Before administering Sentinel Spectrum, weigh your dog first.
  • Administer Sentinel Spectrum once a month on the same day of each month year round.
  • Provide the tablet directly into the mouth or mix it with food and give. Ensure that the entire dose has been swallowed.
