Is the dog back? Norbert would expect him te be.
Up to you, I would assume so, but I don't know what order
Norbert gave. I did not refer to the dog to leave all possibilities open.

If the dog is still confident to find the way back to the house, Nobert will follow him.
The chances of a dog making it back to a place it has only been to once is low, the rain means it can not follow the scent back. All this to say your Survival Ability would not prevent you from failing in this case, but the dice may be good to you.
If you take the lead on getting home you would still need to convince Olaf to follow you and not stride off in his own direction. But that --and convincing him to camp for the night-- might get easier if he discovers he is lost.
