You still hink dogs on treadmills are funny? That's so 2011. Everyone knows that dogs on escalators are the hot new thing.
The dog in this video looks smart enough, but he or she somehow ends up in a public place (airport?) on an up-escalator ramp sans leash (probably because the owner was busy taping this). It may look like he's trapped ont he moving contraption, but don't worry. It all works out for the pooch in the end.
We'd like to see a cat find its way out of a tough situation like this.
