Made of double braided rope this leash is designed with a slip collar style end that fits over the dogs head, the Quik-Hitch lead is an all-in-one lead. No collar needed, simply place the loop slip end around dogs' neck and set the leather slide to fit of the neck. Great for training, working dogs and field dogs. 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.
