Pet Safe Dog Vibration Bark Collar

Can't get your dog to stop barking? Stop the behavior with this humane, vibration-only training collar. When your dog barks, it delivers a harmless but annoying vibration to her neck that stops most puppers mid-yap. Most dogs quickly make the connection! Because the vibration may come from one of two points and the duration varies (there are 10 combinations), pups can't get complacent. Durable and waterproof, with on/off switch for extending battery life, auto-safety shut-off and battery indicator light. Uses one RFA-188 battery (included). Adjusts to fit necks up to 27".
