The past few days the internet was a buzz with the "bottle cap challenge." Now, a new challenge has dogs everywhere wondering what the heck is that in their way?!

The "invisible challenge" involves dog owners lining an open doorway with cellophane, then watching their four-legged family member figure out what exactly is going on. Some dogs are quick to catch on and get by the wrapping...others, seriously have no idea what to do.

What do you think?
