Handheld Bark Buster is the humane way to put a stop to persistent barking.
Train your dog to stay quiet without shock collars or other painful methods.
When the dog barks the Bark Buster emits a high-pitched sonic pulse that’s inaudible to the human ear but highly irritating to dogs.
With a choice of two sensitivity levels to deter dogs each time they bark, it activates up to 20 feet and can even be mounted to a wall with the supplied bracket. Requires 1x9V battery (not included).
