He actually did pretty good! There were somewhere around 200 dogs there, so he went into play mode sooner than I had hoped, but he managed to do a couple of rounds on the agility equipment before that happened. There was a trainer doing CGC testing, which I had him do again (he passed it 4 months ago) and he did well with that. He met so many new dogs, and especially liked an APBT that kept barking at him, initiating play. I think that dog was the one that actually flipped his switch, making him think he was at a romper room festival.
Someone was taking pictures, so hopefully those will show up on the website soon. I did find one from last year that I didn't even know was taken, but that was of Grizz-Bang. Didn't have Baloo then!
