The JULIUS-K9® chest harnesses (Powerharnesses and IDC®Color&Gray® belt harnesses) have been designed for ease of use and for simple application. These types of harnesses are therefore most commonly used during city walks or when working with service dogs. As a result of improper leash use, sizing, or harness adjustment, some dogs can still wriggle out of the harness.
Fetching is a difficult topic. There are dogs who bring back their toys even as a very small puppy, and there are those who simply show no interest towards this type of fun. Fortunately, with a little bit of perseverance, the latter group can also learn to bring back the items we ask for.
