A dog harness suitable for outdoor activities where the dog is on the lead. During mantrailing, the dog is looking for a specific person, following his unique odour in any area. The Julius-K9 mantrailing dog harness has been designed specifically for outdoor activities and searching for people. The anatomically perfectly fitting dog harness with an elastic leash anchor provides optimum comfort for the dog even when it exerts a significant pulling force. During the design of the harness, we paid attention to ensuring that the load should be distributed only on the chest instead of the neck.
