Hello, owner of three dogs. Yes, it does work. I was walking my dogs the other day and I heard my neighbor talking to his wife. He's deaf and talks very loudly. He was telling her how impressed he was at how good the dogs were walking for me. I just smiled and thought, Thank God for the harnesses. The first time my Husky, Dakota, was walking with it on, he kept raring up in the air and yipping because he couldn't drag me like he used to. It was funny. He was sooooo frustrated.
