Great site! I've a tip for gigging guitarists from a friend who's a dog groomer. Whenever they nick an ear or trim a little too close and cut the skin there's a glue used which is completely bio-degradable and dries very quickly. It's used on dog nails so it would stand to reason it would work on road dogs, too. I've never had to try it, but thought I'd pass the tip along just the same.
