My dog had a sore paw yesterday...right before I was heading out to setup for a 3 hour gig. He was looking to me to help him, but I had no idea what happened. I was thinking about him when I was playing....especially when I saw another dog in the audience. When I got hime, he was fine. I think it was an insect sting (like a wasp). I am happy that it was not something serious.
