Recommend for my pit mix.
Size: Large, Color: Blue, Size: Large, Color: Blue
Wasn't sure how this leash was going to be for my dog. He is a pit/border collie mix and I usually have a harness on him. No worries, he was great! Let's me put it on, responds to corrections and is much easier to handle. Why didn't I buy this earlier? Highly recommend.

Does help, but needs constant adjusting during walk
I watch so many Cesar television shows on how to correct dog behavior and see him use a Yellow version on the shows. I see there is not a yellow version of this lead available on the site so that was irritating because I wanted to get what he uses exactly from his show. Anyway, thanks to another reviewer, I knew to buy the "large" size of this for my 40lb dog because she made the mistake of buying the regular smaller size this site defaults to choose. The "large" is not very long, only 2 ft but maybe the rope is thicker. The rope is a light stretchy material so it does not chafe your hand, but it still burns after a while of your dog pulling and you trying to keep it from pulling. I could not imagine trying to use this on a dog bigger than 40 pounds because it feels like it is at it's max strength when I am dealing with mine. My dog likes to eat anything and everything on the ground as we walk so I needed this for the option of the muzzle control feature of the rope. As others have said it acts like the gentle leader halter. Pros: The adjustable slide to "secure" the loop size over your dog's head, behind it's ears is easy to move up and down. The black metal ring works well when you use the second circle to loop over your dog's muzzle. Every time she tries to open her mouth to eat something on the ground she can't. CONS: The adjustable slide to "secure" the loop is too easy to move and therefore I have to constantly push it back down on my dog's head while walking. I am trying to find a clamp of some sort I can clip behind this slider to keep it in place once my dog starts moving. As soon as it begins to slide up from movement, causing the neck hoop opening to widen and she is back to pulling hard.

Such a great tool!
Size: 48" One Size Fits Most, Color: Black
I have had this product for a week, and I have nothing but good things to say about it! I debated for a couple of days as to whether or not to purchase it because the price seemed a tiny bit much for what looked like such a simple item. Now I know it’s that very same simplicity that makes this such an effective tool! Best money I could have spent on my dog! I’ve had my rescue Patterdale Terrier for a little under 3 months and I have quickly found out he is far from being perfect. It has taken a lot of time to begin working on correcting some of his problems, one at a time. Like many dogs, he also pulls when being walked. So what did I do as a regular person in need of quick dog tips? I searched up Cesar Millan videos on YouTube. 😂 I had purchased a Flexi leash two weeks after adopting my dog, and he broke it within another two weeks. While it was disappointing when I first found out, I now see it as a blessing in disguise. Paying close attention on YouTube, I noticed common features in all of the videos where the owners had pulling problems. Most owners in these videos had Flexi leashes, and the dog is always walking in front of the owner, not besides them. All Cesar uses to start making a change are leads just like this one. He never explicitly promotes his lead on his show, but after seeing the immediate increased control using such a simple tool, I decided to look online and found this. So I figured, why not? My dog is 28lbs, so he isn’t big enough to overpower and drag me during a walk. After the Flexi broke, I resorted to using a regular hook-through-the-collar leash. The pulling problem was still there, and would only get worst if we came across a squirrel. As soon as we started using this lead, he’s become much more responsive to my corrections. As soon as he is too far in front of me, even without actually pulling, I give it a quick, gentle tug and a “Chh!” and he‘s learned that he needs to slow down. If he actually pulls and won’t immediately respond to my correction, we’ll sometimes stop walking altogether until he sits, calms down, and realizes that we’ll only walk at my pace. This lead has helped tremendously and there’s rarely ever any tension on the lead when walking now. It’s hard to believe it has only been a week since I’ve started using it, and I don’t believe I’ll go back to using the traditional leash unless absolutely necessary. I would definitely purchase this again! And no, I have not been paid by anyone, nor was I sent this by any company to review it. Just a regular girl who is so happy to have found something that is actually seeming to work!

Worked from day 1
Size: 48" One Size Fits Most, Color: Black
This leash is the best thing I’ve ever bought for my dog. He’s 1 year and 4 months old, and I’ve bought at least five different harnesses since I got him, including very expensive ones like DogfriendlyCo. He pulls with every single one of them. I bought this leash a while ago, but I only used it once because I was afraid he would get hyperactive and choke himself. He hated it at first and tried really hard to get out of it. Today, after four months, I decided to give it another try and omg! This is the first time I’ve been able to walk him without feeling anxious or embarrassed. He walked by my side the whole time, and the leash stayed loose. Iwould only pull a little when he wanted to go ahead of me. I could tell he enjoyed the walk and so did I. I’ve tried it a couple more times just to make sure it wasn’t luck, but this thing really works. Highly recommend.
