We've had our black lab puppy for around a year now, but only recently has she started to be afraid of our living room. She isnt actually afraid of the room however, only the doorway you have to walk through to get in there. After experimenting, i stood in the doorway with treats (which labradors cant resist!) however she stands just outside the door and barks, before bolting past me and into the room. For whatever reason, shes fine with being in the room and being in the hall outside but not that tiny, one metre squared area around the door. Can anyone offer some guidance?
