Help a shelter dog get adopted
Donate a WUNDERball to a shelter dog and we'll match it ball-for-ball — one-time or monthly. Playful dogs get adopted faster. Every ball tracked, every donor recognized.
Clip one end to each dog’s collar or harness, then attach your leash to the center ring. The natural rubber arms flex independently — so when one dog moves left and the other goes right, there’s no tangling, no crossed leashes, no wrestling match. Works with any standard leash, but pairs best with the WACKYwalk’r system for no-pull + no-tangle in one setup.
Small — 6–15 lbs per dog (Chihuahuas, Yorkies, toy breeds)
Medium — 16–60 lbs per dog (Poodles, Boxers, Bulldogs, Beagles, and Doodles)
Large — 61–100 lbs per dog (Great Danes, Rottweilers, Mastiffs, most Labs and Goldens)
Walking dogs of different sizes? Size to the larger dog. The smaller dog will be comfortable — the bigger dog sets the strength requirement.
Ships within 1–2 business days from Hatfield, Pennsylvania. Free shipping on orders over $57. Not happy? 30-day tail-waggin’ guarantee — return it, no questions asked.
Two dogs, one leash — here’s how
01
Clip to both dogs
Each end snaps onto a collar or harness with a heavy-duty swivel clip. Takes 5 seconds. No special hardware, no adapters.
02
Attach your leash
Hook any standard leash to the center O-ring. The natural rubber arms flex independently, so each dog moves freely without crossing or tangling.
03
Walk. That’s it.
Both dogs get their own space to sniff and explore. You hold one leash, stay in control, and never untangle a knot again.
Everything that makes it better
📏
3 ft. — stretches to 4.5 ft.
Short enough for city sidewalks and crowded crosswalks. Stretchy enough to not feel like a choke chain.
⚡
Cuts pulling force by 50%
Independently tested. The elastic core cuts impact on your shoulder — and your dog's neck — in half.
✋
Traffic handle
Second grip right at the collar. Grab close in a split second at busy intersections or around other dogs.
🌿
Natural rubber latex
Dogs resist chewing it. Weatherproof, UV-resistant, and built to outlast a drawer full of nylon leashes.
🎨
9 colors, 3 sizes
27 combinations for every dog from 5 lbs to 150 lbs. Pick the color that matches your dog's energy.
🛡️
Safer than retractables
No locking mechanism to jam. No cord to snap back. No cord burns. Vet-recommended, chiropractor-approved.

You asked, we answered
Will this work on my dog if they're a really bad puller?+
Yes — the worse the puller, the more dramatic the result. The leash works through physics, not behavior modification. Most customers with severe pullers are our happiest reviewers.
Is 3 feet too short for a normal walk?+
It feels short the first time — and that's the point. Within 1–2 walks, your dog naturally adjusts their pace to walk beside you. The stretch to 4.5 ft. gives enough room to sniff without bolting.
Can I use this with a harness or only a collar?+
Both work great. For strong pullers, we recommend attaching to a front-clip harness for maximum control.
What if my dog weighs right at the size cutoff?+
Size up. When in doubt, go larger — a slightly loose leash is always more comfortable than one that's too tight.
How does the CRAZYcoupl'r work with this?+
The Urban Walk'r is the perfect length for 2-dog walking when you add the CRAZYcoupl'r. Both dogs get the no-pull benefit — you hold one leash.
CAUTION: This product contains natural rubber latex which may cause allergic reactions.
