It's always entertaining when dogs teach themselves tricks to get the most out of any play session, but this 3-year-old Australian shepherd named Secret has taught herself a trick that is both entertaining and incredibly impressive.
She learned how to pull her own sled up a hill, hop in it, and stay in it while she enjoys the ride down. (Hover to play video.)
Secret's best friend, a 17-year-old girl named Mary, has taught her some pretty remarkable tricks. But, of all the things this brilliant dog can do, sledding has to be one of the most fun for her to do and for us to watch.
