Dog Refuses to Come in House Until Imaginary Door is Opened [VIDEO]

This dog stands at an open doorway, waiting until the owners pretend to open the imaginary door.

It's not clear why the dog waits outside even though the door is open and the owners are calling him in.

Some speculate the dog has ran into the door when it was closed enough times, he'd rather not test his luck until the door is open. Others say the owners, in an effort to prevent damage to the door from jumping and scratching, trained the dog to wait until the door was opened and he was invited in.

No matter the reason, this pup isn't about to make a mistake entering the house until he's absolutely sure it's the right thing to do.
