About the PetArmor Extend Flea & Tick Collar

This flea and tick collar protects dogs for up to eight continuous months and does not need a prescription. It kills and repels fleas, ticks and lice on contact, so pests don't have to bite to be affected. It also targets flea larvae, which helps break the flea life cycle.

The collar starts working 24 hours after it is first put on. After that, new fleas are killed within two hours, and protection against new ticks starts at 48 hours.

The active ingredients, imidacloprid and flumethrin, are released slowly from the collar. They spread into the skin and coat. The protection is water-resistant, so it keeps working through swims, baths and rain. The formula is odorless and non-greasy, with no chemical smell or residue.
