This is the most awesome dog accessorie I´v ever bought! The twin leash for my small italian greyhounds Ammi and Essi. Before I had a mess everytime I walked with all four dogs. As they are different sizes I have had a problem with the biggies stumbling on and get caught in the small ones leashes. Now its like a dream! You cant believe how much help I have from this item. Its amazing :)) The small girls are almost always without leash but when walking the streets I always use a leash for safety of course.
