Our Alpine Two-Dog Lead is quite simply one of the finest double dog lead systems around. Not only does this double braided rope leash include our "comfort grip" handle and heavy-duty hardware, it comes with our innovative "Slide-Lok". With our unique Slide-Lok the user can easily adjust the distance between the dogs, can make one side longer than the other or lock the dogs side-by-side when the situation calls for it. We guarantee you will not find a better or more elegant two-dog leash on the market. We recommend the 7/16" diameter rope for dogs over 50 lbs., the 5/16" diameter rope for dogs up to 50 lbs. and the 3/16" diameter rope for dogs under 17 lbs.
