Prepare to have your little heart MELTED, people.
Melted by Duncan Lou Who - the boxer dog whose rear legs were severely deformed at birth, and amputated as a result.
Duncan Lou-Who hasn't let a little thing like that ruin his life, though. Just check out his first time at the beach, above - and marvel at his speed, balance and sheer sprightliness. "NONE of the video has been sped up," write his owners on YouTube. "This gives you an idea of how fast Duncan really is."
Adda boy, Duncan!
