Second handle too high up on leash
Color: Black, Size: Large
Slip lead length provides your reactive dog with too much range to lunge. The second handle is great but it is too high up on the leash. If the slip lead length was shorter and the second handle was lower, this product would be awesome.

Great lead alternative!
Color: Blue, Size: Large
This works great for an alternative to just a slip lead. I work in a kennel and it makes it a lot easier to grip for the dogs that pull a lot.

Won’t stay in place
Color: Blue, Size: Large
While the leash was nicely made, the lead would not stay in place. The slide to hold the “O” ring in place kept sliding there for the leash would loosen. The padded handle was nice for sure
