I never used ShowSheen on burrs, but I have always used a product made for horses called Cowboy Magic. It's a light oil that acts as a conditioner and leaves a shine on the animal (dog or horse) and burrs literally fall out of the coat with it. You just rub a small amount in your hands and then through the coat. You can find it at tack shops or online. It's amazing stuff!
