The multiple swivel points and adjustable length make this my favorite coupler even as someone who works in the pet industry.
Great
I'm able to walk two of my retrievers now without getting completely entangled in leashes!
Really good quality, easy to adjust, and works perfectly for my chihuahuas
As the puppy grew walking two golden retreivers to the beach became more challenging ... until the Wonder Coupler arrived! No more twisting and untwisting on our morning walks to run on the beach. Izzy (6 yrs) and his son Pumpkin (8 months) walk side by side, stopping to sniff and check pee-mail together all the way! It does work best with the bigger dog (who does not pull) to be hooked on the top and the pup (who is learning not to pull) to be hooked under his chin). All with Wonder Walker quality for daily walks in all kinds of weather.
