It’s physics, not punishment. The WUNDERleash stretches from 4 to 7 feet of natural rubber, absorbing your dog’s pulling force and returning them to your side — gently, every time. The extra length gives your pup room to explore while still teaching them not to pull. Most dogs get it within three walks. No treats, no clicker, no trainer needed.
Small — up to 20 lbs (Chihuahua, Pom, small terriers)
Medium — up to 60 lbs (Poodles, Boxers, Bulldogs, Beagles, and Doodles)
Large — up to 150 lbs (Great Danes, Rottweilers, Mastiffs, most Labs and Goldens)
When in doubt, go one size up. Strong puller near the upper end of a weight range? Definitely size up.

Why it works — the science in 3 steps
01
Dog lunges forward
The elastic core stretches up to 7 feet, absorbing the burst of energy instead of jerking their neck — safer and more humane than any chain or prong.
02
Resistance returns them
The natural rubber contracts back to 4 feet, gently redirecting your dog to your side without you yanking. More range than a standard leash, more control than a retractable.
03
They learn. Fast.
Pulling stops being rewarding. Most dogs show dramatic change in 1–3 walks. No trainer, no treats, no special collar.
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.

Overall rating: 4.5 / 5 from 186 reviews.
This leash is unique in that it has a stretch factor that applies counteracting force itself against pulling, you just have to hold your ground. It seems to have already made a difference in his pulling me along, but, of course, there's always the odd squirrel around to test the limits.
Great leash! Our cane corso responding well and not biting the leash even when going with the Pet Sitter David from Rover. Highly recommend!
We've bought 5 leashes and loved every one!
Perfect This is exactly what I was looking for. This is going to make walking both of them so much easier. I got the coupler to go with the leash. Thanks for a great product.
It has really helped me walk our 50 pound very strong dog with more control and confidence. She has pulled me over before ( where I fell) but the new leash is comfortable for her and gently pulls back when she lunges. It’s been so helpful!! Thank you.
This leash arrived just in time! Mimi's old leash was badly worn, and when it broke as soon as we walked out the door, I hooked her up to the Wacky Walker. Sasha, Mimi's sister, is 10 pounds lighter, so she uses the medium weight. These leashes give me great control over 2 rambunctious Border Collies!
Great product.. they really do work... and immediately.... I've bought several over the years and being in rescue...i highly recommend these to everyone that has, or adopts a dog
Great doing business with you.
Walking my 75lb Lab is so much more pleasant. He's learning not to pull.
WUNDERleash – The Original No-Pull Dog Leash
Store owner replied: Thank you so much, Diane! We love hearing this! ❤️ The WUNDERleash really does help teach them that pulling gets them nowhere — and it makes those walks so much more enjoyable for both of you. Give your 75 lb. Lab some love from the WACKYwalk’r team! 🐾”
This leash caused my dogs to pull harder. It did not work at all.
WUNDERleash – The Original No-Pull Dog Leash
Store owner replied: Hi Gayle, We’re sorry to hear the WUNDERleash didn’t work as you expected. The WUNDERleash works a little differently than a traditional leash. When your dog pulls, it’s important not to continue walking or pull back against your dog. Instead, simply stop and allow the patented stretch of the leash to do the work. As the leash stretches and releases, it naturally reduces the constant pulling force, and most dogs quickly learn that pulling no longer gets them where they want to go. Walking while your dog is pulling can actually encourage them to pull harder, regardless of the leash being used. We’d be happy to share a few training tips or videos that demonstrate the proper technique. Many customers find that once they understand how to use the WUNDERleash, it becomes a much more enjoyable walking experience. Thank you for giving it a try, and we appreciate your feedback.
I have strong dog who wants to chase trailers. The leash hasn't stopped him bolting for them but it has absorbed the force of the bolt so I am not longer being pulled.
Don’t like it. Need to return for a refund. Pls advise how to do this.
Here’s the deal. The previous purple Wacky Walker that I had purchased twenty-three (yes! 23!!) years ago for my previous SCWT, who lived to age 13, finally broke a few weeks ago! My current SCWT is now twelve years old and enjoying her new leash. When she passes, we’ll donate the leash to a local rescue dog. Thank you, W W!! And I do not need discounts for future purchases. I’m too old for another pup. But, thanks for a fabulous product!
Literally the most comfortable leash I’ve ever owned. Super love 5 stars ⭐️
I ordered the medium size as was suggested on the site for my 18lb reactive Aussiedoodle Oz. I followed the recommendation to stand firm when he reacts and let the leash do the work. To my surprise this strategy actually caused him to pause and look back at me. Also, the leash is comfortable to handle! Good boy Ozi and good job Wacky Walkr! Susan L
Easy on the hands and my Field Spaniel seems to enjoy it.
Would LOVE, LOVE, LOVE a hands-free version!! The bungees I was using don't allow me to control my 3 rescues as confidently as I believe a hands-free version of your product would. Just think about it!! Happy to test if needed :)
Great visibility.
Doesn’t help her not pull
WUNDERleash – The Original No-Pull Dog Leash
Store owner replied: The key with the WACKYwalk’r is to stop and let the leash do the work instead of constantly pulling back yourself. 😊 When your dog starts to pull, stop walking for a moment and allow the stretch/resistance of the leash to gently redirect and correct the behavior. Once she relaxes the tension, continue walking. Most dogs start figuring it out pretty quickly with consistency. It’s designed to reduce the constant jerking and tugging battle — especially for strong pullers. 🐾
Works well.
Alicia’s are great. I did not want to do dog choke collars so they’re hooked onto their harnesses. They’re two little busy dogs and they used to pull like anything and they definitely slowed down on the yelling . I highly recommend.
My dogs loves this leash.
This leash acts like a sling shot, I fell down into rocks
WUNDERleash – The Original No-Pull Dog Leash
Store owner replied: Hi Sandra, We are very sorry to hear about your fall and truly hope you are okay. The WUNDERleash is designed with a patented stretch section intended to reduce the harsh jarring and shoulder strain caused by sudden pulling, but every dog, handler, and walking situation is different — especially with strong or reactive dogs and uneven terrain. Safety is always our top priority, and we sincerely appreciate you sharing your experience and feedback. – WACKYwalk’r Customer Care
It is the best dog leash!!
WUNDERleash – The Original No-Pull Dog Leash
Store owner replied: Love hearing this—thank you, Louis! 🙌 We’re so glad you (and your pup) are enjoying the WACKYwalk’r / WUNDERleash. That stretch and control really makes a difference on walks. Give your dog an extra belly rub from us 🐾
Too heavy for smaller dogs..
WUNDERleash – The Original No-Pull Dog Leash
Store owner replied: Hi Tim, Thanks for the feedback — we appreciate it. You ordered a Medium, which is designed for dogs up to about 60 lbs. Every pup is a little different though, so we’re curious — what does your dog weigh? If it feels too heavy, no problem at all — you’re welcome to return it for a refund. We want to make sure you end up with the right fit for your pup. Just let us know 👍 — WACKYwalk’r Customer Care 🐾
I have had this same leash with another dog, but I have a new rescue dog that pulls and lunges so I thought this would be a good leash for her, but sadly it is not and I returned to using a standard leash that allows more control.
WUNDERleash – The Original No-Pull Dog Leash
Store owner replied: Hi Sean, Thank you for giving WUNDERleash another try, and we especially appreciate that you had success with it previously. Every dog — especially rescue dogs with strong pulling or lunging behaviors — can respond differently to different leash styles and handling setups. The WUNDERleash is designed to reduce the harsh jarring and strain caused by pulling, but we completely understand that in some situations a more rigid leash may feel like it provides better immediate control for a specific dog. We appreciate the honest feedback and wish you and your rescue pup all the best. – WACKYwalk’r Customer Care
Military service was not kind to my shoulders. I cannot walk dogs over 20 pounds that are not exquisite trained and perfectly obedient without one of these leashes. I’ve been using them for over 15 years now and will never be without one. Even my shoulder surgeon was impressed by these, started recommending them to his patients. If you’re on the fence, go for it. These leashes are brilliant.
Although it does not keep my pup from wanting to pull on walks, it definitely prevents her from pulling my arms as much as she did with her other leash, so walks are much more comfortable. I wish it would come in a longer option, but overall I love it and am glad I purchased it!
Worked as advertised. Love it!
It does seem to help him to walk well on the leash. But the problem I have is when the leash stretches too far it’s very hard to pull it back. It feels like it will snap back. Any suggestions? Meri Sue
I like the look and feel of the leash but haven't tried it on my worst puller yet. I think it will help once we get motivated.
Great quality product
Shipment came faster than expected.
This leash is great. In combination with a harness, this leash corrects our 65 pound Goldendoodle's pulling. It is a total game changer when it comes to taking her for walks. I like the heavy weight of it. I think that weight helps remind our puppy that she is tethered to a person and not the other way around. The cushioned handle is also very comfortable. I have arthritis in my hands and it makes walking her a lot less painful.
Leashes make walking my Doberman Pinscher and Silver Labrador Retriever more controlled because of their resilience.
The leash didn't work as well as I hoped for my dog's pull tendencies. It's a bit too bouncy for me.
I never received my order I had a follow up email few weeks ago But haven’t heard anything since
WUNDERleash – The Original No-Pull Dog Leash
Store owner replied: Hi Eric, I’m very sorry for the delay and that you never received your order — and I apologize that you didn’t hear back after your follow-up email. That’s absolutely not the experience we want for our customers. We’re sending out a replacement order right away to make this right. Thank you for your patience, and please don’t hesitate to reach out if there’s anything else we can help with. — Customer Care Team WACKYwalk’r
I have a very strong staff 65-70 lbs so going to up to 150 might have not been the correct one
Much easier to walk them with this
