I have a escape artist of a dog that i was trying to make sure could be left outside for a few minutes on a chain without running away by getting out of many other harnesses and collars. This harness fits my dog very well with the adjustable areas around the neck, behind the front legs, and around or behind the rib cage. She is 60 lbs and I can pick her up with the handle and she feels safe and the harness does not rip or break. I love the multiple placements for leashes, especially the one on the front to discourage pulling. If your dog escapes harness, this will solve issues and is durable!
