Good Teaching & walking leash, heavy duty
Size: Large(1/2"-6ft), Color: Black
Very good dog leash for heavy or big dogs. Not for the little guys. Be sure to keep it above their neck as to not choke them. Good training leash for walking large dogs or very strong puppies of a larger breed for training purposes. Walking everyday is so good for them and you! Helps keep them following you, walking on your side or while your , rollerblading, cycling .. Teaching relaxing ways to walk your dog, gently n not choking them by keeping it high behind their ears! The dog will love you. Watch Dog Whisperer on how to walk your dog safely n dog not pull n walk you! If your dog is really heavy, strong n big, get the strongest one. Be sure to keep their regular I’d collar on. This is not a replacement for a collar. Do not ever use this to tie up your dog, not safe. Just have a daily long walk with your pet dog. Mine is 45 lbs and walks wonderfully with me with this leash. No pulling, tugging or jerking. Note: can be chewed by puppies. Never leave them alone with leash on.

The best thing ever for you and your dog!
Size: Large(1/2"-6ft), Color: Black
This leash has been a blessing. I rescued a dog several years ago and I'm not sure what the previous owners did to him but there was no way I could get a harness or collar on him. I tried and being that it's just me and he is about 130 lbs, it wasn't going to happen.
I ran out of ideas but saw one trainer video where she slipped it on her dog while giving her dog a treat. That was a great and all but Thor has never taken a treat from my hand. I would have to put it down. Anyway I did and slipped the leash around him and it worked so smoothly. He was surprised by it but I praised him for it.
I do this daily now because the slip leash is so easy to work with. I can't thank you guys enough.
The quality is there and made well. If you need to train your dog on a leash, you can't go wrong buying this.

Good, heavy duty leash
Size: Large(1/2"-6ft), Color: Purple
I bought 2 of these leashes for my dogs after seeing a dog trainer use something very similar. Before this, I was using a conventional clip-on leash and a flat collar, and I found that my dogs pulled a lot.
Well, my young and insane terrier mix still pulls like a freight train, but my older dog has responded well to this leash. It's been significantly easier to get him to heel and to move him along when he decides to spend an entire day sniffing a patch of grass. I'm sure my younger dog will calm down a bit when I work with her some more, and this leash will help.
The rope is stout and it has reflective thread woven into it. I didn't realize how visible it was until a light shone on it. I wouldn't rely on it to keep you safe in low visibility areas (wear a reflective vest if you walk at night and there's traffic) but it can't hurt and is a nice touch.
The rope is soft enough that it doesn't chafe either dog's neck, and it's thick enough that it doesn't hurt my hands even when the dogs spot a rabbit or squirrel and YANK as hard as they can. I certainly have no fear of this leash breaking-- it looks like you could tow a small car with it.
This is an excellent, inexpensive slip leash to use when walking or training an obstinate dog.

Great Quality & Easily Useable!
Size: Large(1/2"-6ft), Color: Yellow
These are the BEST leashes, not only for new dogs that are training, but for every day usage. My dog is 40 lb. Bernedoodle and he is off-leash a lot of the time because he wears an e-collar and responds well to this. So these leadshes that slip on and off easily are terrific! They are great quality, nice weight, perfect length at 6 feet. I have several in different colors.
