Optical illusion puzzles are all the rage on the Internet these days, with plenty going viral including “Find the panda in the snowmen”, “Find the Kourtney in the sea of Kim’s” and so many more.

But this one has tricked us. Where’s the dog on the bed?

Is he on the blanket? Between the pillows? Maybe he’s up against the backboard of the bed?

Yep, it’s the last one. We bet you feel pretty dumb right about now (unless you spotted him straight away, you smarty-pants).
