UWS makes the dog box known throughout the sporting world as the finest-built way to transport and protect your valued dogs. Beautifully done; one at a time; built by hand, sturdy enough to give a lifetime of pride to an owner. They are available in single and double door models. Double door units feature a center aluminum wall separating each compartment. Rails are a standard feature on UWS dog boxes and serve a practical as well as stylish function. Rails are set into strong extrusions and then welded to the box, forming a secure place to tie game, coolers, or other articles.
