Sentry Fiproguard Plus is a topical squeeze-on flea and tick treatment for dogs. It uses fipronil plus (S)-methoprene, the same active ingredients as Frontline Plus, to kill adult fleas and ticks and stop flea eggs and larvae from developing. It is applied monthly between the shoulder blades and is sold in size-specific tubes matched to the dog's weight. It suits owners who want a lower-cost alternative to brand-name spot-ons, though it is not waterproof the way some newer oral products are.
