Novartis Program Flea Killer for Dogs 21-45 lbs. 6 Month Supply Flea & Tick
Program Flea Control is a non-prescription, monthly, oral flea preventative for dogs. Program controls flea infestations by preventing adult fleas from reproducing, effectively breaking the life cycle. Lufenuron, the active ingredient in Program, is an insect development inhibitor (IDI), which prevents the production of chitin, a necessary substance for eggs to build a hard outer layer for protection. When the eggs have no hard outer shell, they become vulnerable to the animal's immune system, and cannot develop to adults. The lufenuron attaches to the animal's body fat, slowly and continuously releasing, to to eliminate chitin. As Program Flea Control does not kill existing adult fleas, talk with your veterinarian about additional flea treatments.
