The Release N Run Dog Collar is a collar and leash in one. This unique leash-collar combination is primarily made for off-leash dogs and is not intended to be a walking leash. The retractable leash is built-in to the collar to allow for quick control of your dog when needed; on a trail, to and from the car, on the beach, etc. 
The Collar is made from Cordura Nylon and the leash from an ultra-strong Spectra (Kevlar) cord that retracts into the collar with a nylon handle. The retracting mechanism was originally designed for extended use by scuba divers in salt water. This great collar is a must-have for outdoor adventures with your dog!
