Omg...I am laughing as I relate to almost "all" of these behaviours. Wallee's favourite thing is throw his ball down the stairs and whine for us to go and get it..lol..My husband says this is Wallee's "stupid human" game...hahaha..Stupid human fetch my ball...lol...He also pushes toys under the couch and whines for us to get them. I remember when he was a pup throwing toys in the garbage cause they fit under the couch. I recently had a friend over who suggested I wedge a pool noodle under my couch. I am tempted to go to the dollar store and pick one up to see if it works..Wouldn't that ruin part of the hiding game??
