Features top-grain bridle leather that is incredibly strong, but supple, softening over time but remaining sturdy for a reliable collar that is comfortable for dogs to wear. Made with top-grain European bridle leather for strength and endurance, and sewn down both sides with bonded thread for added strength. Please note that leather is a natural, porous product. If the leather becomes wet, some colour run of the natural dye may happen. Leather collars ought not be saturated with water. If the collar becomes saturated, allow it to air-dry naturally and do not use heat to speed the drying process. To keep the item in tip-top shape, we recommend treating with a leather conditioner annually. When fitting a collar make sure there is a two-finger gap between your dog's neck and the collar.
