Dogs are naturally pretty happy-go-lucky, so to saw that you've got the happiest dog in the world is quite a statement. One look at Gluta, though, and you've gotta agree, she's one happy pooch.
Gluta was a stray dog rescued in her native Thailand. Her owner discovered troubling symptoms that eventually turned out to be cervical cancer. After surgery and chemotherapy, the lucky pup was eventually deemed cancer-free. From the joyful look that never seems to leave Gluta's face, it's clear she's made a full recovery. These days, Gluta is the star of her own Tumblr where photographer Sorasart Wisetsin documents her adventures. Whether lounging in fields of grass or wearing a variety of items on her head, Gluta brings joy wherever she goes.
