Query: It worked great the first week...

When I first bought this leash, I couldn't have been happier. My dog could run all over and the leash would never get caught in her legs. I could let her have 5 feet or 25 feet. It's like she wasn't even on a leash. That all changed in the second week when the cord stopped retracting. Now I have 20 feet of cord laying on the ground and getting caught between her legs.Do yourself a favor and find another brand.
