This is amazing for handling our two 50lbers at once. They get a bit more space and slack when it is clipped on the back loop of a harness rather than a collar.

The bungee leash technology is amazing at stopping your dog from reefing your arm off when they see a squirrel.

This is a great product. However, I feel that it was designed for small dogs. I have two medium size dogs and the distance between them was not long enough; they kept peeing on each other. So, I ordered a second one and everyone is happy again!

Great quality and very hardy clasps

Works great as a double-connection for the leash to help with pulling - yet giving the dog extra space to sniff/explore.

I thought our two greyhounds would have trouble adjusting to walk so close to each other, but that was far from what happened. After just a few minutes they figured out how to pause when one pup stopped to sniff something our mark a spot. They even figured out how to duck under the coupler when they want to switch sides. The coupler makes it possible for one of us to walk them at the same time.
