The Catalyst limited slip collar provides control and pressure communication, making it ideal for dogs that are prone to bolting or trying to back out of their collars. The collar will tighten with leash pressure, then loosen when pressure is released. The Catalyst features hardware that prevents the collar from fully tightening.
