Figured I’d update this thread, in case anybody is curious. Also because I have no one else to brag to. 
So the past couple of weeks, nobody else has shown up to our puppy class. It seems that the other two enrolled have quit, so my dog and I have had it to ourselves. The trainer has been bringing a couple of her own dogs to class, just so my puppy can get the socialization/distraction aspect of the whole thing, which is kind of her.
Anyway, since we have the class to ourselves, and since my puppy is already proficient in everything covered in the course, we’ve been spending about the first half of class reviewing and refining, and the second half of class playing with some agility obstacles.
So far, we have conquered the tunnel (with and without turns), the chute, the A-Frame (set very low, obviously), and little bitty jumps. My puppy is OBSESSED. If we walk anywhere near an obstacle, he is making a bid to do it. He’s more interested in the obstacles than in people or other dogs, which is HUGE for him.
So, apparently we will be starting down the agility road! I’m still interested in IPO, so we will probably still explore that option as well, but since he’s having so much fun right now with the agility, I’d hate to take it away from him!
Still more obedience to learn, but it’s nice to see him so interested in the agility!
