Is the Release N Run strong enough to hold my dog?
Yes, as long as you follow the guidelines for the maximum recommended weight for the collar sizes.
How is that little cord strong enough to hold my dog back?
To achieve such high strength in such a small package, the Release N Run utilizes Spectra® cord, a material similar to the Kevlar®. Spectra is made by Honeywell® and is one of the world's strongest and lightest fibers. Spectra is, pound-for-pound, fifteen times stronger than steel and is more durable than polyester. To maintain the strength of leash it is important to use the leash properly. <strong>Do not let your dog chew the retractable cord, and be careful to not let the stretched cord rub against abrasive surfaces such as rocks or trees, this will cause fraying and compromise the cord.
