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.
