Do your dogs do this? Mine go nuts no matter what room they're in or even if they were previously sleeping. They also go crazy if they hear any kind of jingling noise. They thinks its sounds like keys and daddy's home. Or if they hear a knock(they think someones at the door). Sometimes I like to mess with them and I will knock on the wall or table without them seeing me do it. They all start barking and looking around trying to figure out where it came from.
Its pretty funny.
What noises do your dogs get all crazy over?
