Our first dog was a very cheeky/smart Schnauzer/Maltese. He didn't like us leaving him at home, but rather than barking or whatever, he'd literally pull every item of clothing off the clothesline, and pile it up on the lawn.
We forgot something one day, and returned home quickly, finding him hanging in mid-air, mouth clamped on a sweater. He seemed torn between trying to rip it down, or nonchalantly pretending nothing was happening...lol
