Duncan Lou Who, a boxer pup, has been making the Internet rounds lately, due to his inspirational story.
Little DLW was born with a severe birth deformity that required both of his hind legs to be amputated, The Huffington Post reported.
Panda Paws Rescue said Duncan has a doggie wheelchair, but that he doesn't like to use it.
And after watching this tear-inducing video, Duncan doesn't seem to need it at all! He runs around, completely stable, and seemingly unaware that he's missing his hind legs. This was his first time at a beach, and you can just see the complete joy and wonder on his goofy little puppy face.
