Yule Log

The WPIX fireplace manages to always make me feel so warm.

I once watched a PBS documentary on the tradition of the yule log. It was not the WPIX fireplace or the yummy cake often made during the holidays. What I saw was some sort of meat or fish dish that was buried. A dog urinated over the area it was buried and this supposedly added to the flavor?  I watched this as a child so I don't completely trust this memory. I have searched for some Scandinavian recipe that is like this but have yet to find yet. Maybe the memory is completely off or maybe I dreamt it. When I think of a yule log, that is always what pops up in my mind... What was that? If you can set me straight please do.
