Jesus, if there was one thing that makes me want to kill my dogs!
Mine go nuts too. Once you are inside they are fine.
Mine sounds like he’s 150 pounds of kill behind the front door when he barks. Then when you come inside he pees in the floor from excitement and licks you to death. He might bring you a toy to play tug with too. He’s for sure an alarm, not a protector. He’s still pretty cool though.
