I like these. Quick on/off, can be used as a gentle leader, also. I don't like the leash clipped onto the collar because if the clip breaks - they are plastic and rot over time - then your dog is gone, possible dead because, after all, dogs have no sense of running in front of a 3,000 pound vehicle.

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.
