I wanted this to work so badly but it broke on the first walk of a 25 pound dog. Please!  I was going to give up completely on this concept until I found a seller on Ebay who makes such a high quality hands free leash I can't stop gushing about it.  Go on Ebay and look for TJ's Custom Made Pet Supplies in the store's section.  I shop enough on Amazon for them to deal with this referral to Ebay.
