Most pranks are centered around humans, but what happens when you try to prank a real dog with a stuffed dog puppet trying to protect it's bone? You get to laugh, a lot.

What's so hilarious is how the real dogs react to the stuffed dog's bark. Some of them are scared, some are curious and others are just plain bold (or incredibly smart).

If it looks like a dog and sounds somewhat like a dog, it has to be a dog ... or is it?

That's why this gag so fun, even the dogs are confused.

A dog may be mans' best friend, but dogs beware, there's a prankster out there waiting to play a gag on you.
