I remember our first couple of shows...boy howdy did we have some work to do as well as learning. As long as you enjoyed yourself, that's really what matters. I was supposed to attend my first show of the season last week but had to pull out at the last minute when things simply weren't going well (sick with a cold all week, still worked 60 hours, clipper blades that wouldn't cut for the final clipping, etc.). I finally admitted defeat and threw in the towel. Our next show is next Sunday and I'll be preparing all week in an effort to avoid the same issues this time around.
Can't wait to see how things go for your next show outing. He's a lovely boy.
