Program Flea Control for dogs and puppies comes in the form of Flavor Tablets. Program Flea Control works by preventing flea larvae and pupae (eggs) from developing. Since Program Flea Control works at the egg stage, it can take several weeks to realize its full benefits. Program Flea Control is given once monthly by mouth and should be given with dog food. Each packet has 6 tablets providing 6 months of protection for your dog. The new Program Flavor Tablets are tastier and easier to administer.
