Dog harnesses can be great tools for dogs, but they are difficult to put on, and the extra gear often gets left at home. ThunderLeash is the perfect combination of simplicity and functionality. For those times you just need a standard leash for a quick walk or for times when your dog is well behaved, simply connect the ThunderLeash to your dog’s collar just like any other leash. But when pulling might be a problem, simply wrap ThunderLeash around your dog’s torso and slide it into the harness slot. Now whenever your dog pulls, a gentle pressure is applied to his torso and the pulling will quickly cease. With the ThunderLeash, you will finally be able to walk your dog, instead of being walked by your dog.

we have had our beloved dog Bella for three years - she is 85 pounds lab mix - she has a very sweet temperament but - trying to walk her from day one (we adopted her from a shelter when she was 10 months old) has been a challenge to say the least. i would say i have average strength for a 45 year old mom - but - we live about a block away from a park where i regularly walk her - or i should say - she would walk me! lol there are plenty of rabbits and squirrels that she wanted to chase - not to mention runners, other dogs, and even occasionally she would try to take off after a passing truck - every day, either morning walk, or evening walk - i would have rope burns or cuts on my hands from wrapping her rope leash around my hands trying to hold onto her if i would see something coming up - and God help me the times I didnt! after 2 years - and ignoring friends who kept telling me to get one of those spiked choke collars (I just couldnt do it - they look so medieval to me!) i ran into someone at a "Dog Daze" event at a Bass Pro shop - who had this product on his dog - i found out about it by my apologizing to the poor man over and over with my Bella jumping on him in excitement and wagging her tail and trying to run around his ankles and his dog - he laughed and said he didnt mind that his own dog used to be the same way til he bought this leash. With nothing to lose except the pain in my hands and arms - I purchased this - and it is THE BEST purchase I have ever made - inexpensive and COMPLETELY effective!! I actually ENJOY walking her now - she isn't pulling with her whole body weight and half choking herself during the whole walk and she actually just walks at a regular pace next to me! Yes - there have been two or three times in the past 3 weeks that i have had this where she forgets and darts for a squirrel or rabbit - but she stops HERSELF - no more pain in my hands, no arms pulled painfully - I could not be more happy with my purchase and thank GOD i ran into that nice man that day - I would recommend this product to ANYONE who is having a hard time walking their enthusiastic fur-baby - only wish I had found this sooner!!

The harness I had been using with my dog was snagging on his long hair. I was very interested in this Thunderleash because it didn't have as many moving parts as the other harness. And I liked the gentle squeezing aspect of it.What I find is:My dog's collar is higher than the dog in the photo. So this does seem to affect my dog's airway when he lunges because it pulls his collar tight. I'm probably going to have to get a different collar. It would be helpful to know what kind of collar works best, and to know where the collar would ideally be fitted on the dog. Maybe this varies from breed to breed. I have an Australian Shepherd with silky long fur.The harness-collar connection slips around. Maybe I have the "loose" setting too loose to work quite as in the photo but it's about as tight as I can comfortably connect it on my dog (meaning, I can get his hair out of the way; any tighter and there's a problem with his hair getting caught and pulled when I'm attaching the leash into the harness position).The thing slides around. After we've been walking a while, the leash-collar hardware is sliding down the side. If I pull he contraption back into place, my dog thinks I'm leading him to go the other way. Basically I have to alternate sides with my dog (have him alternate which side of me he's walking on) to keep the harness more or less in place.My dog will be getting a summer haircut and perhaps these issues will be resolved when there's not so much long fur to be taking into consideration.I do think this Thunderleash is an improvement over the standard harness. I like the tightening aspect, and I like that it has hardware to prevent it from over-tightening.

I tried halter leashes, choker chains and harnesses but I couldn’t get my dog to stop pulling aggressively. The Thunderleash may be the answer.The leash is a clever design with a pentagonal shaped shackle with a leash slot on the side. I looked at a similar design (controlleash.com), but I feel the Thunder Leash design is superior as you may have less wear on the leash material.In the default state (attached directly to the collar), the pressure induced on my dogs chest, was not enough of a deterrent to stop pulling. I have a 60 lb Border Collie that is high energy (neurotic) and constantly pulls. I added a carabiner between the shackle and collar that allowed the leash to loop around my dogs diaphragm/belly area. This seemed to be more effective. You can also accomplish this in the default state but when the dog relaxes, it tends to slip forward back to the chest area. He still pulls but I think he’s getting the idea. My wife feels that he definitely pulls less.The only con is the leash gets twisted if your dog is highly active and constantly maneuvering like my dog does. A design suggestion would be to add a swivel shackle at the handle to prevent this.A customer’s review on the packaging states he was able to control his 110 lb Rottweiler but I’m a little skeptical as the side slot on the shackle may not hold up to larger dogs. The leash material and thickness appears to be adequate but not as beefy as the LeashBoss leashes.

Niet wat ik had gehoopt of verwacht. Je hebt een erg korte looplijn over zodra je een grote hond hebt aangelijnd. Veel te kort en veel te stug materiaal. Erg teleurstellend

So far the only lead/harness that had made it bearable to walk my very strong & difficult rescue staffie x boxer. I have tried numerous different non pull/head control devices (that worked for my other rescue (staffie x mastiff) & this is the only thing that has really made a difference. He still pulled a bit but nowhere near as hard and this was on the first walk! Hopefully as he gets more used to it he will become even easier to walk.

This is my second thunder leash. My previous dog was about 50lbs and a hard puller. I had initially used a prong collar with her, but I always hated it. Once we got this leash she could walk with me no problem! She would pull, yes, but it was manageable and not painful for either of us. Now I have a tiny maltese puppy that isn't too fond of walking on a leash yet. She will lay down and resist, and if in a harness she will find a way to wiggle out. With this leash she can't wiggle out and I can gently pull her to come along. Best training tool ever! Worth the money!

J'ai un berger allemand qui tire comme une brute, j'ai voulu tester cette laisse sans réel conviction mais ca marche très bien, il a arreté de tiré.Le système est une laisse harnais qui a chaque fois qu'il tire va serrer au niveau des cotes et faire comprendre sans douleur qu'il y a trop de pression dans la laisse.Attention elle ne fait pas de miracle, comme il est réactif, un chien, une voiture...il démarre et se fiche de la pression mise.
