The choke lead is mainly used for dog trials.  When you have your dog running courses, this lead is perfect because it can be removed quickly and easily.  To sum it up, it is like having a collar built right in to your leash giving you no more hassles with 2 pieces and a lot of hardware. Patterned Polyester is the most common material used because it has a nice shine to its color, and a smooth feel that is not harsh on your dogs neck.  This comes with an O-ring for hardware, wide range of pattern, and 4 standard lengths.  However, there is an infinite number of custom lengths!  If you need a bigger lead, just give us a call @ 541-741-0658 and tell us what you need.
