Frontline plus trusted by pet parents for decades, Frontline Plus for large dogs is a topical treatment for fleas and ticks that weigh 45 to 88 lbs. The monthly spot-on formula treats and prevents fleas and chewing lice. Frontline Plus Purple for dogs stops the growth of immature life stages of fleas and thus breaks the flea life cycle. The composition kills flea eggs, larvae, and ticks, including the ticks that can transmit Lyme disease. The topical flea and tick treatment for dogs also helps control sarcoptic mange infections.
Frontline Plus for large dogs is made with two active ingredients, fipronil, and s-methoprene. Once applied, the liquid formula quickly gets spread all over the dog’s body surface and holds within its sebaceous glands. These glands fill up the chemical liquid constantly on dog’s skin, and coat, keeping them protected.
Fipronil kills fleas by causing paralysis due to excessive stimulation of their nervous system. S-methoprene prevents the growth of the parasites and stops eggs from maturing into adults. The composition is recommended for use in 8 weeks and older dogs.

I have been using this product since 6 months on my doggy. It works excellently and killed all the fleas within 24 hours. I would recommend to all the dog owners who are looking for a better flea preventative.
Good product that works.
