PetArmor Extend Flea & Tick Collar for Dogs

Help keep your dog or cat protected year-round with PetArmor Extend Flea & Tick Collar. Trusted by pet owners for over 15 years, PetArmor® Extend™ provides continuous flea, tick, and lice protection for up to 8 months in a convenient, easy-to-use collar. Powered by vet-recommended active ingredients imidacloprid and flumethrin, this dual-action collar kills and repels fleas and ticks on contact — meaning pests do not need to bite your pet for the collar to be effective. The advanced polymer matrix design slowly releases active ingredients over time, distributing protection across your pet’s skin and coat through their natural oils for long-lasting coverage. PetArmor® Extend™ not only kills adult fleas and ticks, but also targets flea larvae to help break the flea life cycle and reduce reinfestation. The odorless, non-greasy formula leaves no messy residue or chemical smell behind, making it comfortable for everyday wear. Designed for year-round use, the water-resistant collar maintains protection through normal bathing and wet conditions without removal. The collar also provides protection against chewing lice and is available in different sizes for dogs and puppies over 7 weeks of age.
