Found girl.

At the risk of being overly analytical about a game of Hide and Seek between a toddler and a Newfoundland–shouldn't Sebastien the Newfie be a little better at finding someone? Especially a toddler, a group notoriously awful at Hide and Seek. 

They've obviously played the game before, so there's about a fifty-fifty chance of the girl hiding behind that couch. Newfies are great family dogs, so it's possible the big guy is humoring the girl and throwing the game. If that's the case, good boy. But if he really had that much trouble finding the girl, he should be ashamed of that effort.
