Collars, Leads, Harnesses leather products are designed for the working dog and to last a lifetime. I personally designed, hand made, and used each of the leather products listed here for over a decade. I wanted a product that not only looked good but functioned exceptionally well and that was a tall order. I have tried and used everything on the market from synthetic to hemp and have come to the conclusion that nothing to me has the fit and feel of fine leather. Our Herm Sprenger products are top of the line and a handler would be hard pressed to find better quality.
