Skout’s Honor’s Stop Marking! Preventative Spray is designed to discourage and prevent marking with natural lemongrass and peppermint oil. Pet owners spray it liberally around the home to discourage dogs from marking or re-marking furniture, carpet or walls, or any other specific areas. The lemongrass and peppermint oils left behind act as a natural deterrent and help prevent dogs from marking or returning to the same spot twice.
