Bark Buster

Does your dog bark incessantly, annoying both you and your neighbours? If so, this ingenious collar-mounted device will solve the problem. A sensor detects barking and emits a high pitched tone that distracts the dog. The dog will soon associate barking with the noise, and stop barking. Simple to use and harmless, the 29” collar can be cut to fit smaller dogs.
