For those of you who use the walkie dog, are you prepared for failure? I was riding today and all of a sudden I noticed that Briar was running up near my font wheel, jsut cruising along! The rope part had broken. I always carry an emergency leash and today, I am glad I did! We were only 2 miles from home but if I didn't have that extra leash, it would have been a real challenge getting the dog and my bike home!
