Use this collar for training and walks only. One correction with this collar and my dog keeps a loose leash. He loves to see me get this collar because he knows he's going for a walk. No more pulling!!! This collar was recommended to me from the Humane Society to correct and control a rambunctious dog! This collar won't choke your dog. It has limited pinch for correction only. Remove links to get the right fit. High on the neck and snug, not tight. Use sharp corrections and immediate release with praise. Your dog will amaze you how fast he/she learns!!!
