Penny is a four-month-old German Shepherd and Collie mix who lives with a new family after being adopted from an animal shelter a few weeks ago.
As you can see from the video above, she's pretty happy in her new home, spending a lot of her time in the field near her owners' house, happily playing fetch with herself over and over and over.
Aided by a friendly hill, she trots up to her master only to drop the ball at the last minute, forcing her to go and get it again, and again, and again. Fortunately, she loves it, and now footage has been posted online, so do we.
Sure, it's not the most impressive trick in the world - Pudsey needn't get too scared of Penny taking his perforing pooch crown any time soon - but it's still worthy of our much-loved YouTube dog tricks hall of fame...
