Some dogs live their entire lives for one thing and one thing only: A rousing game of fetch.
And some are so committed to the game that they might not realize that the human they are trying to play with isn't a human at all, but rather a lifeless doll sitting on a couch.
Watching the video below is slightly painful: As much as these dogs might want this doll to play fetch with them, us humans know the truth. She never will, and seeing the looks of disappointment on their faces is slightly awww-inducing. Not to mention the fact that it will make you LOL.
