How long until Frontline Plus is waterproof? Once FRONTLINE Plus® / FRONTLINE Tri-Act® / FRONTLINE® Spot On has been applied it is recommended to keep your pet out of the rain and away from watercourses for the next 48 hours.
Can dogs go swimming after applying Frontline? Yes. FRONTLINE PLUS is water-fast. It is OK to bathe your pet before using FRONTLINE PLUS, but the coat should be completely dry prior to application. In the 48 hours immediately after treatment, do not bath, shampoo or let your dog go swimming.
Does Frontline wash off in shower? Frontline products contains fipronil, the active ingredient that kills adult fleas infesting a dog. Fipronil works its way into the hair follicles, where it remains trapped by the sebaceous or oil glands, making it resistant to being washed away with bathing.
