  • How to Apply

    Remove collar from protective pouch directly before use. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar.

    1. Insert the end of the collar through the buckle.

    2. Adjust the collar around the dog’s neck without tightening it too tight or leaving it too loose. As a guide, it should be possible to insert 2 fingers comfortably between the collar and the neck.

    3. Pull excess collar through the loop(s). Collar length of greater than 1 inch (2 cm) beyond the loop(s) should be cut off unless it is on a growing puppy, where some additional length may be needed for adjustment as the dog’s grows.

    Visual directions for using one of the Hartz flea and tick collars for dogs.

    The collar should be worn continuously for the 6 month protection period. Check periodically and adjust if necessary, especially when puppies are rapidly growing.

    Replace the collar after 6 months for optimal tick, flea and mosquitos protection.
