Agility Puppy

We have been discovering that Pickles loves playgrounds, tunnels, and climbing on things.  At puppy class he was the first one to climb up the slide onto the little tykes play structure.  He also loved running through the holes underneath the structure.  We've taken him to the playground down the road a couple times and he voluntarily goes down the little slide; he also enjoys running up the stairs and across the bridge.  Recently we bought him a little kids play tunnel from target.  He absolutely loves running through it.  He'll chase any toy through there, grab it and run back through the tunnel to bring it to you.  Outside if you get him running with you and then run past the tunnel pointing him in the right direction he'll run right through it and come out jumping and smiling on the other side.  Sometimes, we leave it up in the dining room and he runs through it just to entertain himself.
