Teach your dog not to bark with the PetSafe Basic Bark Control. Designed to significantly reduce or stop barking altogether, this collar features six levels of progressive correction. Starting at the lowest level of vibration, it will continue to increase correction if barking continues. It also has an automatic shut off that kicks in after 80 seconds. Made for dogs over eight pounds and with necks up to 28-inches, this collar is also waterproof and can be submersed up to five feet so you can continue to enjoy all your favorite outdoor activities.
