This very good boy can't tell whether the screen door is open or not

Dogs are lovely creatures. But, let's be honest, vision is not their strong suit.

That's probably why this adorable doggo had a little bit of a hard time figuring out what was up with the screen door of his owner's house.

Twitter user Jensen Kendall uploaded a video of her dog and his misconception about their screen door. This very good boy apparently can't tell when the screen door is closed, which means that his owners have to pretend to open it for him.

This little girl is doing a good job of pretend-opening a door, though.

By the looks of it, the dog is so convinced that the door is closed, he doesn't even notice when his snout technically passes the threshold.

Theory: this dog is a vampire, who can't enter a house without being invited first.
