We got Suds this new harness since he gets crazy excited when he gets near other dogs on walks. Josh can handle it but it's just a little too much for me so we decided to see if this would help reduce the pulling. I don't think Suds is completely sold on the idea yet. Whenever the leash got near his mouth during our test walk, he started chewing on it like crazy; I think he thought he might be able to gnaw himself out of it. No such luck.
