Frontline Shield Flea & Tick Treatment is a powerful topical solution designed specifically for medium-sized dogs weighing between 21 and 40 pounds. This extra-strength formula starts killing fleas within five minutes and ticks within one hour after application. It effectively kills adult fleas, flea eggs, larvae, chewing lice, and repels mosquitoes and stable flies that may carry diseases such as heartworm and Lyme disease. The waterproof formula deposits in the sebaceous glands of your dog's skin, continuously replenishing protection even if your dog gets wet.

Easy to apply with a squeeze applicator, it ensures thorough coverage by applying to specific spots on your dog's back depending on size.

Frontline Shield is ideal for pet owners seeking reliable parasite control to keep their dogs comfortable and healthy during all seasons.
