The PetSafe Audible Bark Collar is unlike any others on the market. This unique type of bark collar uses SoundBurst technology to detect your dog’s barking and immediately releases a sound (resembling the spray of an aerosol can) to distract them from their barking. 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 activating. This audible bark collar discourages barking quickly and consistently, and it really works. In fact, 70% of users report their dog barking less within the first few days of wearing the audible collar. Your pet deserves the best. Trust PetSafe to help keep your pet healthy, safe and happy.
