Whether your dog needs a light reminder or a stern correction to make him stop barking, Cabela's Gun Dog No-Bark Dog Collar will take care of it. With six levels of progressive correction, the collar delivers a light electrical stimulus when it senses barking. If barking continues, the correction level increases until the dog stops. After a period of silence, the collar resets at the lowest level so there's no risk of overcorrection. Waterproof collar is ideal for outdoor use. Uses easy-to-replace CR2032 lithium batteries (included).
