Comfortis Plus Green for Medium Dogs 20-40 lbs

Comfortis Plus for medium dogs is a #1 vet-recommended flea and worming treatment for medium-sized dogs. It is a beef-flavored chewable tablet that efficiently kills fleas and protects against intestinal worms and heartworms. It is a fast-acting flea control treatment as it starts killing fleas within just 30 minutes of administration. This way, it prevents flea infestations and controls flea allergy dermatitis. This reliable treatment also treats and controls intestinal worms like hookworms, roundworms, and whipworms, and prevents the deadly heartworm disease.

Comfortis Plus Green is recommended for medium dogs from eight weeks of age and weighing between 20 and 40lbs (9 and 18 kg).

Comfortis Plus (Spinosad+Milbemycin Oxime) Flea, Worm & Heartworm Treatment

Comfortis Plus is formulated using two powerful treatments: Spinosad and Milbemycin Oxime. Spinosad works on fleas, whereas Milbemycin Oxime works on internal parasites like intestinal worms and heartworms.

Spinosad acts on the nervous system of the fleas, triggering their nerve cells. This leads to involuntary muscle contractions and tremors, which leads to the destruction of fleas. It starts killing fleas within 30 minutes and eliminates 100% of them within 24 hours.

The other active ingredient, Milbemycin Oxime, attacks intestinal worms and immature forms of heartworms. The anthelmintic effectively controls heartworms and intestinal worms protecting the dog from harmful infections.
