WHAT Makes the American River Choke Free Patented Design unique from other harnesses? The MOST important reason is MULTIPLE SAFETY FEATURES!!

• ROTATION ANGLE Best Fit - The American River Harness has a Best Fit Rotation Adjustment that will fit any size chest if applied correctly. The Velcro is designed to cover the entire end. The Best Fit occurs when you angle the closure back toward the Tail of the Dog. You can actually change the fit around the chest, by angling the ends when you close the Velcro. Please SEE PICTURE.
