If you put a dog on a bicycle and it rolls down a hill, does it know what's happening?

Barry the dog was once a skateboarder, but he's now graduated to the tricycle. Or his owners have graduated to putting him on a tricycle instead of a skateboard. He does sit very cutely on the seat there, looking kind of zen as he gently rolls off into the sunset, but I don't know that I'd call him a bike "rider."

In the YouTube description the truth comes out:

His owner Wayne, 29, explains: "One day we had a skateboard out and he started playing with it. We were just playing and we put him on the skateboard and he loved it, so we started gently pushing him on it and it just went from there." The adventurous dog soon set himself the much harder challenge of riding a trike. Wayne says that the family were outside playing with Barry one day when they spotted the trike and decided to see if he would sit on it. "And when we moved away he just carried on sitting there and we thought 'What's going on here?'" The couple take the precaution of helping Barry steer the bike with two lines of fishing wire.
