VIDEO: Adorable Dog Doesn’t Really Understand this Glass Door

This is ridiculously cute.  This adorable Yorkshire terrier may not be the smartest pup you'll see all week, but he'll certainly make you laugh. The dog is 100 per cent sure that the glass patio door is closed and no amount of calling him in is going to make a difference, it's not happening. That is, until the family play along and "open" it for him. Brilliant. http://www.youtube.com/watch?v=udbMNZDQS48
