It works nicely so far for my Border Collie Fly ☺️

I have a 49 lbs pittie mix and she's strong. I don't feel that the harness made a huge difference in her pulling. She just ends up pulling side ways. And also, since it's clipped in the front, the leash often gets wrapped on the other side of the neck. I find myself having to adjust the leash to the side I'm walking on.

So happy with the customer service! Was able to resize the chest strap smaller so it perfectly fits our Golden, Thank you for being so responsive to my emails!

This works so well!! My dog doesn’t mind wearing it and he went from being a moderate puller to not pulling at all.

At this time I would say works great.
