LOUISVILLE, Ky. (WHAS11) -- A puppy from Vancouver, Wash. has become an internet star.
Duncan is missing his two back legs but that isn't slowing him down.
More than 3 million people have watched this YouTube video of the dog running along the beach and it was only posted last week!
Turns out--this was Duncan's first trip to the beach.
Duncan was born with his back legs fused together almost like a pretzel.
That's why he had to have them amputated. But as you can see his adoptive family says he's healthy and happy.
