So, in my case there are no dogs but doors are stuck too.
Save is just after leaving Storage room

If your in the place that I think, the door that is stuck, can be break down with Pick Axe.
Got the same problem in Overture. I got my key and a gas can, used the saw on the wooden plank at the door and it's still closed. Pick Axe doesn't work.
Already tried reloading older save.
How do I open the these door? Is it a bug or do I do something wrong? Can someone send me a save after getting through the door to the Auxilary?
