Our dog, Max, just loves to play hide-and-seek. We discovered this while playing ball and the ball happened to land under a bush. Max had so much fun looking for it that we've since made it into a game for him. 'Course, being a lab/spaniel mix, he's got the whole "hunting/sniffing" thing in the blood anyway. So funny seeing his head under a couch with his rear in the air!
I was looking for his ball one day with
my head under the couch with my rear in the air, and there was Max right beside me, looking as hard as I was (except when he was licking me LOL). Wife was laughing too hard to snap a pic, but maybe next time.
