This intermediate bite sleeve is the next step up from a puppy bite sleeve. The top is made out of padded body shaped plastic. The arm is made from leather that is very flexible and has a short bite bar. Because of these materials it enables the dog to bite over the bar and onto the flexible sleeve enabling the dog to get a good grip and allowing the helper to feel the quality of that grip. Used by top schutzhund helpers/trainers world wide. Jute cover sold separatley.
