VANCOUVER, Wash. -- A two-legged dog has captured the hearts of millions after his owner posted a YouTube video of him going for a run on the beach.

Duncan, a boxer, had to have his hind legs amputated in October because they were deformed.

Duncan's owner, Amanda Geise, runs an animal rescue center called Panda Paws Rescue. Geise decided to adopt Duncan for her own family and said she expected the dog to use a wheelchair.

But Duncan learned to pick himself up and walk again using only his front legs.

"Since the day he started to move and toddle around and start walking, he picked up his back end and carried it, so he doesn't know any different," Geise said.
