The SportDog NoBark 18 Deluxe Dog Collar is designed to safely and consistently stop your dog’s nuisance barking. This bark control collar includes 18 levels of stimulation with no programming required. Just turn the battery to the on position, put the bark collar on your dog, and select the correction range you want. The NoBark 18 also features Perfect Bark® technology that provides firm, fair and consistent bark control that requires both vibration and sound to trigger a correction. An automatic safety shut-off eliminates the risk of overcorrection. With a waterproof collar receiver, a long-life, replaceable lithium battery and an adjustable collar for neck sizes between 6 and 28 inches, the SportDog NoBark 18 Deluxe Dog Collar is the way to go.
