Dual leash still tends to tangle a bit
931752
I bought this dual leash to replace a dual retractable leash, figuring that this type might work better to avoid tangled lines and leads wrapped around my legs.  This is a little better, but it still tends to end up wrapped around my legs more often than not.  We're working on that.

This is great for letting my puppy fetch in the park while still obeying laws to keep her on leash. The drawback is that it tangles easily. I can live with that to have the reassurance that my sweet girl will not be able to run off.

The leash works great for walking both of my dogs.  It is one of the larger double leashes I could find, and the bungee design is great for the dogs.  They used to yank each other every time they caught a wiff of something.  It is not good if you have dogs needing corrected.  If I try to pull back on the leash to get there attention or pull them from something, the bungee design does not work in my favor.  But the construction seems great, and I love it!

I have mixed feelings about this product... I bought two - one for each dog. My Heeler is very well-trained and knows not to tug on the lead when I'm walking her so the fact that this lead retracts puts tension on her neck and is counterproductive to what I've taught her. She will not pull on this lead and just sits right next to it, looking at me in a confused matter.

My other dog is a Coonhound who has proven to be difficult when it comes to leash training. She still pulls on the leash while I'm walking her and has no problem pulling on this retractable lead. The fact that I've made it acceptable for her to pull on this lead but not the one I use for walking is counterproductive for her training.

If you are planning on training your dog not to pull on a lead while walking, I would advise against this product.

Even when tightened down it still moves alot on my dog also the leash connect point hits his legs when he runs.

It beats three separate leashes. And it works great with just two dogs. But three can still get twisted up. If I could change anything, it would be that the clips that attach to the ring swiveled as the ring does, which might help some.

Solid leash for what I needed though after a month of hard use it's starting to show some small signs of retraction trouble.

Works great.  Free of tangles. Only concern is at time it doesn't completely retract

There must be an art to using these 2-dog leash couplers, one which I have not yet mastered.  My hope is to attach it to two different harnesses and walk my 2 pit bull mix dogs without them tangling each other up or tangling up me in the process.  So far it hasn't gone well for the 3 of us.  But as far as the item itself goes--it is very solidly made, with sturdy metal pieces and strong fabric--so it deserves the 5 stars I'm giving it.

Decent leash. The way it adjusts means there are two straps that form a loop near where it attaches to our dog's collar. This can be a problem because the straps can separate and our dog step through it. We initially bought this for use with our 6-month old puppy, but he's all over the place when we go for walks; so he was constantly getting wrapped up in the leash. We switched to using it with our 3.5 yr old, 50lb dog and have had much better results. His collar is further away from his feet, so he typically only steps through the leash when going up stairs.

Anyway, the quality is good. Worth the price of admission. Not sure we'll buy another, though.

I am not sure if I'm using it incorrectly.
If the dog is facing me pulling away from me, she can somehow get out of the harness, but is already so tight it is almost clipping her fur whenever I'm putting the harness on.
She is also still pulling here and there, and it's not like she was put on a spin or anything.

I bought this leash to replace a much older model by the same manufacturer. The old one had a round nylon braided cord that retracted smoothly every time and never twisted because it was round. This leash has replaced that with a flat cord and that one change has essentially ruined the leash. It always twists and tangles and gets caught retracting. I have to constantly pull it all the way out and twist it back to it's starting shape/position in order for it to retract all the way, and I need to constantly pull at it to keep it taught otherwise it won't retract. I'm always left with 2-3 feet of cord that doesn't want to retract back into the leash and it causes me to not have as much control over my dog as I should have. None of this was an issue with the older model of this leash. I absolutely hate this leash.

My dog still pulls tremendously with this. She's so scared of people and objects so she tends to pull and try to get away from whatever situation is going on that bothers her. I'm training her to learn how to not do that. It's gonna take some time, but the leash did seem to help a bit when she is calm (and not in that afraid state). But I wouldn't say this is a cure for my dog. I still keep the Petsafe Harness on her just in case as well so I can easily change it if needed. That one is a bit more secure. Either way, I can use the Thunder Leash as another leash if I need it.

Nice long leash with an on board poop bag dispenser. It's a cord rather than a ribbon which I like best because the ribbon style catches more wind and makes things just a bit awkward to me. I bought an additional stick on light for the side of it that has a decent forward white light and flashing red rear light. The only thing that gives me any pause at all is the leash lock. It works just fine as far as locking goes but it can sometimes give me just a small amount of problem releasing. It does work but it is a little tricky for me to disengage. Probably my fault not theirs, not sure though. All in all I would have to recommend it.

Been on two long walks with this new leash and my 27 lb Frenchie pulls more than ever. I also have to constantly re adjust were the strap goes because as he pulls it slides off his chest. Disappointing as I was hoping this would be a solution.

My dogs are getting use to this but I would rather the part where they attach was on a swivel or something that didn't tangle.

My dog gets tangled around this thing regardless of the swivel... so frustrating. I can't get it far enough in the ground to not get tangled around and I tried everything to get it in as far as possible. There is no way she would be able to get this out of the ground but because I cant get it down all the way she entangles herself. I guess I wish this was shorter...
