Presents become a little more special when you are given them by surprise. It seems same is true for dogs.

In this video, YouTube-famous dog Maymo was given a birthday gift by a surprise. Not knowing that it's his birthday, he's having a nap on the sofa.

The owner moves into action: tables, chairs and other things are moved away to create a mysterious space. A little startled, but it doesn't concern Maymo enough to do anything about it.

Then, a large cardboard box appears in front of Maymo. Now he's interested!

Now... Action!

Out of the box comes thousands of colorful balls. Maymo doesn't hesitate much before he dives into the sea of balls.

Maymo then comes up with all sorts of ways to enjoy the surprise gift. Maymo only got 100 balls a year ago; having 10 times as much must be exciting!

One. Lucky. Dog.
