Looks like one dog has run into a glass door one too many times...
Twitter user Kendall Jensen posted video of the family dog sitting on the back patio waiting for someone to open the door so it can come inside. But the door is already open, and even though the family is calling it to come inside, the dog still thinks it's closed. Finally, one of the kids walks over and pretends to open the door, and the dog walks in.
