20 ft Check Cord Biothane

Water proof bio thane check cord. Check cords are great for teaching future off-leash skills such as Recall. Gives you a way to quickly get ahold of puppies but let them run freely and play. All of our puppies start on Check cords before they ever move to an e-collar. I highly recommend these over nylon. They wipe off are easy to see and do not tangle in tall grass.
