Josh Kwellerwrote a review of Ruffwear Knot-A-Leash on July 9, 2009
I purchased this leash after my puppy's last leash got unhooked when she was playing with another dog on the street. (With her new-found freedom, she ran into the street and almost gave me a heart attack when she was nearly taken out by a car.) With this leash, I never have to worry about that again! The locking carabiner absolutely will not open unless I want it to, but the leash material itself is top-notch. Finally, the handle even has an extra loop onto which you can tie waste bags, so they stay out of your way. Brilliant!
