He might only have two legs, but he hasn't got a single worry in the world.
If you missed the video a few months back of Duncan, the two-legged pup visiting the beach for the first time, then boy howdy are you about to have a good time when you click right here. So much happiness.
Anyway, Duncan is back with another video, released last week, that explains the story behind him and how he came to be internet famous. Duncan had to have his back legs amputated as a result of serious birth defects, but both he and his owners were determined not to give up.
As a result, he now lives a normal life just like any other boxer pup, and he couldn't be happier. There's a lot more to it than that of course, so feast your eyes on the video for all the info.
