This pup proves that one may be alone but does not have to be unhappy about it. Not sure if he self taught this act, but sure looks like he is having a great time playing. All it takes is a ball and a staircase to make his day. This is something all us dog lovers should remember. Our pets love play time. even when no one is around.
So always remember, when no one wants to play with you, just make up your own game and play by yourself. Lesson learned here. Carry on good boy!
