The contoured protective sleeve for adult dog handlers is very durable, lightweight and reliable. It is perfect for working with strong working dogs trained in service, K9 and IGP clubs. Used and recommended by international trainers in Europe. It absorbs impact force very well and adapts perfectly to the pressure and angle of the bite (minimizing the risk of the dog's jaw dislocating). The flexibility of the sleeve makes it easier for the dog to reach the natural bite reflex, the so-called fixation. Made by hand with high precision to ensure the safety of the helper and the dog during training.
