This puppy doesn't need you to throw her ball, thanks

Some dogs can drive you crazy with their endless requests to play fetch. Not this self-sufficient pup. All Penny needs to amuse herself for hours is a ball and a hill. Demonstrating a vivid imagination, Penny leaps after her ball rolling down the slope with a surprised bark, as if she wasn't the one that made it happen in the first place. Man's best friend doesn't need a friend all the time, apparently.
