I LOVE this harness. I have an 11 year old pit bull who loves to hike, but she pulls like a train. Just got this harness last week and put it on her and it is going to be perfect. She got out of her last harness during a hike two weeks ago and scared me to death, so I did some research and landed on your Front Range harness and I could honestly not be happier. I think it is going to be durable and difficult for her to get out of, as well. Thanks for a great product!!
