Trying to juggle two big dogs on two leashes was making me insane, and other 2-dog leashes would just tangle into a mess. The Tuenne 2-in-1 is a godsend!! It’s built like a tank, looks good, feels good to hold, and never (I mean NEVER) tangles!! The swivel at the junction and swivel clips just work beautifully. If you have two dogs, you have to get this. It’s pricey, but the quality and functionality make it worth every penny!
