If you want to know how to be happy, hang out with a dog. They don't have to think about happiness. They don't plan on happiness. They take it as it comes.
Dogs prove that you can be too smart to be happy. But you can never be too dumb. Dogs are just right. Not too smart, not too dumb. Dogs are born to be happy.
The fact that you're there, with your dog, taking pictures of your dog and documenting his or her happiness means you are learning well. We can all learn from your dog. You're in the right place at the right time to be happy, with your dog as trainer.
Be there or be square. There is no such thing as a square dog. :)
