You Are Buying: PetSafe Spray Bark Collar PBC00-16368 w (2) 3pack Citronella Scent Spray Refills Spray Bark Collar: Description During bark training, consistency is key. That?s why we designed the PetSafe Spray Bark Collar as a consistent way to correct your dog?s barking without a remote. This spray bark collar detects your dog?s barking and immediately releases a gentle burst of spray to distract him from the mailman or the neighbor?s cat. Your dog will never be corrected because of another dog?s bark or a loud outside noise because the dual detection technology in this collar must sense both vibration and sound before spraying. Because the spray is immediate and consistent, your dog will learn to associate his barking with a correction and change his behavior within as little as 2 weeks. That?s a win for you, your furry best friend, and your mailman. Your pet deserves the best. Trust PetSafe to help keep your pet healthy, safe and happy.
