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. 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.

Best product

Just loved it! My dog never hesitate to take these tasty chews. I strongly recommend this product to all dog owners to keep their furry babies healthy .



My furry pal is on Sentinel Spectrum since last 8 months. This is an excellent product and I have no complaints whatsoever. There have been no noticeable side effects nor any behavioural changes on my doggy after using this product.


Effective and highly recommended

I like this product and have been using since last 1 year on my furry pal. I have to give only one chew a month to treat all worms and fleas. There are no side effects and my pooch thinks its a treat to eat. This is surely a recommendable product.



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.



Spending just a little fortune on Sentinel yield me great benefits as my pucher is always protected from heartworm disease.
