Works great for training dogs to walk with you
Size: Large, Color: Blue
I am a dog sitter and I like these for walking new dogs that I'm not familiar with. The dogs walk better with this type of leash rather than a harness.

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.
