PETLOCK FLEA/TICK/LICE SM

PetLock Pro is a vet-approved monthly topical treatment for small dogs and puppies. This waterproof formula kills fleas, ticks, chewing lice, flea eggs, and flea larvae—breaking the entire flea life cycle to prevent re-infestation. With the same active ingredients as FRONTLINE Plus (fipronil and (S)-methoprene), it delivers fast-acting, long-lasting protection for up to 30 days.

Suitable for dogs and puppies 8 weeks or older weighing 5–22 lbs. Simply apply once monthly to maintain year-round protection and keep your pet comfortable and healthy.
