Can you review the differences between Frontline, Frontline Plus, Advantage and Program. I live in a heavily wooded area and one of my three dogs is especiallly sensative to flea bites. I would like to choose a product that will give the most protection from both fleas and ticks. My dogs already take interceptor for heartworm on a monthly basis as prescibed by their vet. Thanks for your help.
Frontline plus kills all stages of fleas. Frontline only kills adult fleas. Advantage kills all stages and program only sterilizes the fleas. I recommend either frontline plus or advantage. vetcare
