We recommend them frequently to our clients!

I am a veterinary technician and own a dog training facility in Ohio.  I have used many products over the years with varying degrees of success.  I was impressed with the ThunderLeash and its ability to help owners to control their dogs.  Particularly with elderly clients with big dogs, pulling is a huge issue and a reason that many dogs are rehomed.  I love this product!  We recommend them frequently to our clients!

Very disappointed! Not sturdy!

I was SO excited to try out the ThunderLeash for TWO dogs, as I have a pair of mini-Goldendoodles (each under 25 lbs.), one of which pulls like crazy. I fastened each dog into her half of the leash, told them to "sit-stay," which they did, and went to get my sun hat and the time I returned, one of the dogs had chewed half-way through her leash, leaving it totally unsafe. We did not get to take even ONE trial walk before the leash was rendered useless for its purpose. I am hoping that I can get a replacement for only half of the leash, but if I do, I will have to be careful not to leave the leashed dogs unattended for even 30 seconds! ThunderShirt should redesign this leash, and weave a thin metal cable or two into the leash cord, so that it won't break under pressure if the cord gets damaged or partially cut.

Finally, a solution.

Our girl Penny was a rescue and a true wild-child. I had to train her not to chew *everything*, chase everything, and all else under the sun. But her main issue now? Pulling. This girl is barrel-chested, very high-energy, and pure muscle. She needs walks, and I oblige, but she hated the 'gentle-lead'-type nose leash so much that I thought we were at an impasse. Enter this leash! The no-pull configuration truly truly works and is an absolute breeze– she doesn't even fight it, or seem remotely put out by wearing it. I am so thrilled to finally not worry about being dragged around on the ice during the winter months and/or lunging every time she sees a deer. Highly recommend!

A Pully Bully

Andre, a one year old male American Stafordshire Bulldog, commonly called a pitt bull, was born in Sacramento, California. He had been kept on a small apartment balcony and, as far as I can determine, never walked, trained or kindly treated. He'd no leash manners but is a quick learner thanks to the Thunder Leash! All he seemed to know was that to be on leash meant to pull, weave back and forth in front of me and my Service Dog which caused some problems getting from place to place.

I saw the ads for the Thunder Leash as well as other products with a simmilar goal of stopping the pulling and calming the mind of the dog with a gentle " hug" from the Thunder Leash. If fitted properly and used correctly when pulling starts a grentl pull on the Thunder Leash calms down the mind and reduces the need for pulling. We now walk significantly calmer which lowers the stress for all concerned.
My only complaint was thar there were no fitting or use instructions. There is a vidio available but separatly from the leash itself, not a selling point in my opinion. Perhaps this could change? Shouldn't a CD with step-by-step instructions, some of us may need them, be included with the ThunderLeash and like products? I hesitate to rate this product until we've used it for a bit before a valid oppinion can be given but starting with 4 stars is a pretty good start! ;)

Walking my Dog

The leash is a great idea, however a bad design. I purchased the Thunderleash which fits great but needs a swivel where the leash attaches to the harness. It twists and does not untwist to retract. Other than that it would be great purchase even at the expensive price. So therefore since it is money wasted due to retracting, I am forced to give it a 1 star.

Leash Extension

You heard our need. We have a rehome Husky. We have been working with her to eliminate pulling. The Thunder leash works for her. She is much calmer on the leash. We use the short leash as the retractable leash can give her a running start chasing a rabbit. She had broken two leash clips while we were training her. I asked to purchase a clip as the whole assembly is expensive and I had a perfectly good leash. Customer Service politely explained they didn't sell the clips. Well the leash extension solves that problem. Thank you.

We bought this for our 7 month old puppy as we are leash training her and did not want her to have a negative neck/throat experience. We were excited to read it was described as "no pull" and that the chest was involved in how this product is configured. However, what was not clear was that you need your own collar (for a $40 or more price) but more importantly the collar does tighten around the throat when our puppy pulls. We were under the impression all pressure would be on the chest area and not around the neck/throat, so we will most likely be returning this.

Chloe used to walk me . . .

While Chloe used to walk me, within the first 30 seconds she had the Thunderleash on, she stopped pulling completely. I just wanted to test it out when I got it in the mail, so I walked her to the end of my block and back. She did not pull. I literally cried with happiness. I've tried every safe/non-punitive no-pull solution I could find. nothing worked. we were on the verge of spending $500 dollars to have a trainer come to the house and train her to walk on a leash. With the Thundershirt and the Thunderleash we were able to walk down the street without Chloe having an anxiety attack and without her pulling me all the way down the street. This leash is a miracle. Even if you've tried everything, give this a try. I was so surprised.

Cheap Material

My family and I have been using this leash because our dog tends to pull and for a while it did its job, until our dog got a little too excited. He pulled too hard and the leash snapped, I thought this leash's metal parts were made up of full metal, but in reality it was just metal plated. Really disappointed.


Springfield Virginia United States

New design

I bought our first leash almost a year ago for pulling. Since then we've gone through 3 leashes. On the first one the clipping mechanism pulled out of the hook design, the last two the hook snapped off both of them were no more than a month old. The design is great but I don't think the quality of the material is all that great.

Sebastian's anxiety recovery

Hi, my friend and pet Sebastian has always had difficulty walking on the leash without pulling! I have tried so many different leashes, while training him. Nothing seemed to help him. Finally, I purchased the thunderleash to try it out, and it worked SO well. We are now in our second week of loose leash training, and he is making HUGE strides. He is not only not pulling, he is calmer and reacting less and less everyday to other dogs while he is on the leash!

Thunerleash is Amazing!

We adopted an older dog (with issues) two years ago. I really wanted a walking buddy, but he pulls on the leash so much that it's really a chore more than a joy to walk with him. He would pull so hard that sometimes he was just wheezing and choking. We have used a ThunderShirt and that has helped him in general, but I just started using the ThunderLeash two days ago. It is nothing short of amazing!! I was worried it was just another product that promised more than it could deliver, but not so in this case! Two days in a row, we have had a lovely walk without stress. I highly recommend ThunderLeash!!

ThunderLeash Works

My 4 yr old 24 lb Korean Jindo was a pain to take for walks. She loves to sniff and would pull constantly to check out interesting smells. As a result our walks were an exercise in frustration with her pulling one way or the other and me constantly trying to pull her back. I had tried different leashes and training and got no results. I put the ThunderLeash on and we went for our first walk. Instantly she walked right beside me with no pulling. I couldn't believe it! We've had several walks now and it is so enjoyable not to have her pulling, especially on uneven and icy surfaces. Walking my dog is now relaxing and I can tell she enjoys it as much as I do. Thank You!

German Shepherd Would Drag My Wife - or Me!

When we got our German Shepherd puppy, my wife and I knew she was going to be a big dog. From day one, we tried to train her to not pull when walking, but she would always get excited on walks or when we go to the dog park. She always got way too excited and ended up dragging my wife across the parking lot.

Being out of options and desperate we ended up getting the ThunderLeash a couple months ago.

Thank you ThunderLeash for this awesome leash.

A Happy Tail

ThunderLeash is AMAZING! I have an English Bull Terrier, and because the breed is barrel-chested I have a drawer full of harnesses that don't fit or work. It's been impossible, until today. For the first time he wasn't taking ME out for a walk. Thank you ThunderLeash!


Burbank California United States


Keaton is an American Bull Dog and Pit Bull mix. He is 8 months old now and 70 lbs. of muscle. I am a 64 yr. old woman. Taking him for walks was impossible, he was just dragging me no matter how puppy classes we attended. I heard about ThunderLeash and had to try it. ThunderLeash is amazing - it absolutely works! He stopped pulling with a couple of corrections. We now can safely walk and be relaxed in any situation. I am going to recommend ThunderLeash to anyone who has a dog that pulls. Thank you for such an incredible product that works!


Loleta California United States


My dog was a puller; with this ThunderLeash she can't pull me (she does try). I also have the ThunderShirt. My dog used to shake when she heard thunder, bad rain, etc. It's the only shirt she stands still for me to put it on. When I go to take it off, she will sometimes not let me - I realized she wouldn't let me take it off because the dog knows when the rains are coming.

I have a very head strong two year old Siberian Husky. It is in a Huskies nature to pull. Every time I walked her she walked me instead. I was very skeptical of the ThunderLeash, because the dogs they show on TV I thought could have been trained. I basically reached my limit and just gave in. So I placed my order and as soon as it arrived I put the ThunderLeash on my dog, and took her out, and I could not believe it no more pulling. This is the best product ever, we actually enjoy walking now. We take our time and even the site of a squirrel is no match for ThunderLeash. I recommend ThunderLeash to anyone with a pulling pet it will change your life.

ThunderLeash is AMAZING!

Bonnie, our 60-lb terrier mix, is smart as a whip and all muscle, so when she wanted to stop and sniff something during our morning walks it was like throwing out a 60-lb anchor -- all systems STOP! We saw your commercial for the ThunderLeash, and thought we'd give it a try. All we can say is WOW -- she's a different dog now! She walks by our side, and never pulls or "drops anchor". This is SUCH an improvement over using a choke chain and lead -- we'll never go back. Thank you for inventing such a simple, effective and humane product!


Florida United States


Trying to walk Maggie May, my 80 pound lab, was impossible. She pulled so hard I couldn't control her, making it painful for both of us to go for a leisurely walk. Purchased a ThunderLeash - it changed everything! She no longer pulls and walking is no longer painful for her or myself.

Thank you ThunderLeash!

Goodbye harness, hello ThunderLeash!

This the only leash I will ever buy again. I've never been able to walk my 50lb dog without the control of a harness and she would still pull me down the street. From the very first time I used the ThunderLeash, it was a complete transformation. She just gently walked along without pulling. Seven months later and it's still a success. The most important feature of the ThunderLeash is I can quickly change from using it as a regular leash to the security of a harness.
Everyone at my vet's office was amazed at how much easier it was to handle my dog using the ThunderLeash. I've even loaned it to two of my friends to try out on their dogs. They both came back amazed at the difference it made and went out and purchased their own. One of the dogs was an 110lb German Shepard a 95lb Mastiff and a smaller 30lb mix.
Thank you for developing this wonderful product. I'm always recommending it to friends and have had people come up and ask me what she is wearing. I can't say enough good things about it!


Woodstock Georgia United States

Thank you for making a leash that works!

Thank you so much for making a leash that works so simply and naturally for my dogs who love to pull. It worked the very first time and was not uncomfortable or scary for even my nervous dog. I could have walked either my 94 lb or 60 lb dog with just one finger if I had wanted. It’s nice to take them for a walk AND have circulation in my hand. ;-) I’m going to order another so both of my pullers can have their own. Thanks – Awesome product, sturdy and well worth the money!

My 110 lbs. Rottweiler stopped pulling immediately!!!

I just got my ThunderLeash in the mail and OMG! My 110 pound rottweiler that used to pull me all over the place stopped pulling immediately after putting it on. I never thought that just a leash whould stop her. I’m amazed and shocked that my dog that is the size of a horse was walking with me soo easily. A must have and my big baby actually likes it! After I took it off, she keeps walking over to it trying to play with it.

Walks have become so much more enjoyable!

We already love our ThunderShirt and have noticed a huge decrease in our dog Bo's anxiety level since we began using it. Recently we purchased a ThunderLeash and walk time has become so much more enjoyable for us and our dog. Walks have become longer with so much less pulling. Even when used as a regular leash the ThunderLeash is comfortable and allows just the right amount of slack.

I love my Lab Molly, but she has always been a puller on walks.  The ThunderLeash immediately solved the's a miracle!

My clients are thrilled with the immediate and lasting success that they have found using the ThunderLeash!! They are so happy that they pulling has been corrected in such a positive and safe manner.

ThunderLeash has been effective

I’ve been using the new ThunderLeash at our rescue ranch, as well as with my private clients, and I've had immediate results on dogs of all sizes.

Compared to other products, ThunderLeash has been by far the most effective. By naturally placing pressure on the chest, dogs that were once walking their owners, are now walking by their side.

The design is ingenious, and it’s a very well-made and sturdy leash.

Everyone I’ve introduced ThunderLeash to is excited to purchase their own.

Buy 1 ThunderLeash instead of 4 harnesses!

As a professional dog trainer, I've sold the ThunderLeashes to owners whose dogs are good walkers until they get into squirrel country or crowded areas- they can quickly 'wrap' their dog for more control.  Also, the owners of large breed puppies appreciate the ThunderLeash because they do not have the expense of buying 4-5 harnesses as their puppy rapidly grows from 20 to 100 lbs.

It is a very comfortable leash-harness to use and I think the innovative design is great!

My clients love the versatility of ThunderLeash

The ThunderLeash is a wonderful solution for many dog owners.  It’s is a regular leash that turns into a harness that inhibits pulling.  My clients love the versatility of the ThunderLeash and how it works so well.  It’s a wonderful positive training solution to a dog who pulls on the leash.  The buckles on the leash prevent it from putting too much pressure on the dog’s torso.  So it makes a very safe solution for a fun leash walk for both the dog and handler.

ThunderLeash Saved The Day!

I am a volunteer foster parent for golden retriever rescues, and recently was assigned a very healthy, energetic, thoroughly untrained 7-year-old golden male. I am over 70, so his strength became a real problem for my shoulders as well as for danger of being pulled down on stairs or street. I'd used ThunderShirts before with success, and when I saw ThunderLeash by the same company I immediately ordered one to see if I could get some kind of control over this dog. AMAZING!!!!!!!!! I cannot recommend it highly enough for problem pullers (or for worried supervisors!!!). He immediately stops when he feel the pressure start. Now we've progressed to barely having to use the feature, and this leash is SO fine because it's so simple to switch to just leash control without the "wrap." Thank you for a superb product!
