PETLOCK FLEA/TICK/LICE LG DOGS

PetLock Pro is a vet-approved monthly topical treatment designed for large dogs weighing 45–88 lbs and 8 weeks or older. This fast-acting, waterproof formula kills fleas, ticks, chewing lice, and flea eggs and larvae for up to 30 days of protection.

Formulated with fipronil and (S)-methoprene—the same active ingredients found in FRONTLINE Plus—PetLock Pro goes beyond temporary suppression. It breaks the flea life cycle by eliminating eggs and larvae, preventing re-infestation at the source. Apply once monthly to keep your large dog protected year-round.
