The World's Happiest Dog Goes Around Smiling Her Face Off For One VERY Good Reason

Meet Gluta, "the world's happiest dog."

You may be thinking, "well, that can't really be proven." Sure, maybe not, but we're just judging solely based on her demeanor and facial expression - which is always a smile. But she's not only the happiest, she's also one of the toughest.

Only a few years ago, Gluta was a stray on the streets of Thailand, battling it out each day to survive, fending for herself. After being taken in by a shelter, and eventually adopted by her now owner, she developed uteral cancer. But after countless near-death moments, and almost two years of battling, she beat it. Now cancer free, Gluta travels the world, smiling vibrantly everywhere she goes, savoring each and every moment life grants her.
