You know that old saying, “Once bitten twice shy?” We can’t actually prove that this pooch was bitten once but all the evidence proves that it was actually the case. The tiny little cutie went outside the room, and he refuses to go back in because he thinks that the glass door is closed even if it isn’t. Now, that is a sure sign that at some point in the past the pooch’s face slammed against that glass panel. But the funniest thing comes at the end of the video! You have to see this.
