I purchased your gorgeous Leather Harness for pulling and tracking. I was TOTALLY AMAZED at the QUALITY !!!! I am so pleased with it. I have used two of them for years now. No wear to them at all. They are very comfortable for the dog. Comfortable enough that Schautzie goes and brings me her harness when she wants to go out and run. I don't know what my top speed is..but tears were flying from my eyes. But I had Total control of her. If my male hadn't gone up to sniff a skunk all would have been perfect (tomato juice to bathe in takes skunk smell out, thank God)And for a disabled person this was just PURE FUN !!!!
