Good, but not up to par
I have two small dogs, 10 lbs and 12 lbs I walk together at any given time. I ordered the 2 dogs on 1 leash in small due to the suggestion from the site. The length of the leash is perfect, dogs are no longer being tangled up when I walk them. However, my 10 lb dog must be super strong, because she not only still yanks me around, but she's now yanking my 12 lb dog straight out of her harness at times (not safe when it happens near busy street). I wish I had purchased the medium size. NOTE: I have a third dog I walk alone on a medium sized leash from WackyWalk'r with no yanking issues. I have owned two other single leashes from WackyWalk'r, previously purchased from SkyMall.
