This video of a dog and a squirrel playing a tireless game of chase will make you smile

And he looks like the happiest dog in the world.

It doesn't take much to entertain dogs - as this video proves.

David Wagner from Austria filmed this clip of his dog, Mela playing hide and seek with a squirrel before chasing it around and around and around a tree.

Apparently this went on for five minutes before the squirrel eventually ran up to the top of the tree.

If it hadn't that, we imagine that dog would have gotten hours of enjoyment out of it.

Got a bit dizzy there. But look how much fun he's having!
