It's a really well made, sturdy harness, and can't fault the quality. My dog is a bull breed cross with doberman and greyhound in the mix, so she has a very deep chest but skinny neck and shoulders, so the harness is only just big enough on her chest and is too loose on her chest/neck. I bought the harness to use the front ring as she pulls like a train, but due to the poor fit it isn't giving me the control I'd hoped for while training her. She also almost got out of it when she reversed. Lesso...
