The Petlock 6 Month Flea and Tick collar for Dogs is a weatherproof collar that will protect your dog from fleas and ticks for 6 months. Petlock collars contain the active ingredient Deltamethrin (the same ingredient found in Merck Scalibor collars). Deltamethrin is a synthetic pyrethrin proven to kill fleas and ticks through direct contact or ingestion. The collar stays in contact with the dog's skin and, through friction, small amounts of deltamethrin are transferred to the skin where the oils in the coat spread the medication across the body providing an effective barrier against parasites. 6 months of continuous protection Kills fleas and ticks on the dog and in the dog's environment Weatherproof and water resistantControlled release of Deltamethrin insecticide through frictionNo monthly application dates to remember and no messy drops to applySafe for use on puppies over 12 weeksFleas: PetLock Six Month Collar for Dogs provides effective control of fleas for up to 6 months including those that may transmit Flea Allergy Dermatitis, flea bite anemia, and tapeworms.
