During our product development, we pay maximum attention to the health and smooth movement of dogs. Accordingly, an important goal in the design of dog equipment is to protect the dog from the stress caused by even the tiniest tugs and sudden pulls on the leash. We know that smooth movement is even more important in the case of service dogs and search dogs. With this goal in mind, the new JK9^® Mantrailing harness is equipped with an innovative, elastic leash connector. The connector allows the dog not to be disturbed by the movement and tensioning of the leash during work, so that they can concentrate even more effectively on their task, which is finding missing people.
