The SportDOG Brand® NoBark SBC-R allows you to customize the type of bark control that works best for your dog by allowing you to choose from 3 programmable training modes: Temperament Learning, Progressive Correction, and User-Selected, as well as 10 levels of static stimulation. Unlike anything before it, the SBC-R quickly determines your dog's unique bark using our Silent Partner® technology, and filters out all the rest, so it'll perform in either a single-dog home, or a kennel full of barkers. Either way, you'll have the most superior bark detection.
