This video doesn’t need much explaining: A dog, his birthday, 100 balls and a reminder of what it’s like to be happy.

A camera was rolling when Maymo the lemon beagle was given quite the appropriate gift, an afternoon of play with his favorite toy. You can’t help but smile when you see how much fun he has with all those colorful balls.

The video has more than 1 million views on Maymo’s YouTube channel. He’s also got his own Facebook page.
