Feel free to e-mail the savegame, but to be useful it would have to be saved quite soon after you found the animal, but haven't returned it to the village yet.
This is not necessarily buggy if all the mechanics have worked as they should. Eg. ice is thick enough to actually hold the animal weight.
But what sounds odd, and more of an issue, is that the animal wouldn't follow you on zoomed out map. I'd like to find a reason for that.
