Oh, I meant to mention something yesterday...
On the way out the show last night, there was a couple with a beautiful dog standing by the stage door. The dog was a lab/golden retriever mix - beautiful coat - and he was being trained to be a guide dog for the blind.
They all - the couple and the dog - actually sat through the show - and then they waited by one of the exits to "test" the dog. People were allowed to pet him, but he was not allowed to lick or move. And he didn't. It was very cool, and the couple training the dog have been doing this for years.
They noted the one thing that distracts 99% of the dogs - even after they've been trained - is applause. They can sit through other loud sounds, but for some reason applause makes them perk up. -It would be interesting to find out exactly why that would be a trigger for them.
