The Kindness Lead is perfect for dogs with a sensitive trachea as the wider throat and super-soft leather prevents choking. Also great for training puppies. This all-in-one construction is designed with a thumb loop and measured from tip to tip. The leather is  buttery soft yet strong and available in our regular 1/4" width. All crystal combos include a large crystal keeper in addition to the regular keeper that is used to tighten down for a perfect fit.
