K-9 TUFF STUFF started out in 2009 as pure necessity. Our dogs would literally destroy our standard leashes and collars with ease. This quickly became a real problem and real expensive, real quick! Through much trial and error, We started to engineer our own products and sell them on eBay with much success and still to this day maintain a 100% positive feedback rating from our customers.WELL HOW TOUGH ARE THEY?Our leashes and leads are strong enough for a horse but, we engineered them for big and strong canine breeds such as the American Pit Bull, Great Dane, Bull Mastiff, St. Bernard, Rottweiler and many other large breeds. We hand-craft each item we sell one at a time and we believe in the old saying "Quality over Quantity". We believe in doing people right and maintaining good values.
