One little flea can't possibly be a problem, can it?

It can. A single female flea can produce up to 50 eggs a day,1 turning “one little flea” into a full-blown infestation before you even know it's there. Comfortis® (spinosad) for dogs starts killing fleas before they lay eggs and provides a full month of flea protection to help prevent future flea infestations. In fact, veterinarians give Comfortis the highest overall satisfaction rating when compared to other monthly flea control products.2

And Comfortis is easy to administer! A beef-flavored, chewable tablet can be offered as a treat — no residue, no worries about washing off after swimming or a bath.

Comfortis flea protection is available through veterinarians, so you can feel confident you're getting the right dosage for your dog. Ask your veterinarian if Comfortis is right for you and your dog. Or visit our about Comfortis page to learn more before your next vet visit.
