Hello! I've owned a dog before, so I'm not a new dog owner. But this new dog we got about 2 months ago is doing things that are new! He is totally fine and walks around any other part of the house just fine - he's gotten used to things really fast. But when it comes to my room in particular, he will wait at my door for hours, just staring inwards, and then literally bowl you over to get inside for absolutely no reason, then barrel his way under my couch and stay there while refusing to move unless you drag him out. I understand that dogs hide under things when they're scared, but this is really odd. Nothing in my room is a threat - though the cats are in here a lot - and if he's scared of anything in here, why does he want to be in here so badly?
