Where can i get a reinforced pet harness?

My evil airedale was like that too (I really love him, haha) so we went to are pet supplies plus, or where ever you get pet supplies and we got the "gentle lead" which is like a horse harness and they can't pull because it's latched over the head and they don't like it when you have control over the head, but make sure you read the instructions if you get it. You are not supposed to keep tugging just to short strong yanks when she pulls with the "gentle lead" on. Also it comes in different sizes.
