Meet Duncan Lou Who, a two legged dog that was saved by Panda Paws Rescue, an animal welfare group. His first YouTube video went viral back in November, but he is doing so much better right now. Throughout his recovery, Duncan Lou Who has learned to run very fast for a two legged dog. He can’t stand using his wheelchair so the group decided to take him to the beach in order to give him the space he needed to run wild and free – and the end result will make you happy!
