Our stockman collars are for working dogs. Made from 25mm-wide double-layer double-stitched nylon webbing. They will never break. G uaranteed. As well as strong construction, these collars feature a heavy duty two-bar nickel-plated buckle. A unique feature is placement of the clip-on ring before the buckle, rather than after it. This centralises the pull onto the collar and the dog's neck. Also, the clip-on ring is a substantial 36mm diameter, 5mm section, making clip-on easy, even in the dark.
