Very tired right now, from an early morning and a long day in the sun. Here are Pictures. He assaulted me at the line in both events today, very embarrassing (almost lost my shorts). The Hypothesis is that he is uncomfortable having to run "naked" -- that is, without his collar on. This makes some sense for me, so tomorrow we intend to try the events with his collar on -- this will prevent his run from being able to be a Qualified NADAC run, but so be it. I really hope that is it. We can get around that through training a lot easier than the alternatives.
He was otherwise lovely and well-behaved the whole time.
