Lod

Lod lives in Falkreath and serves as the town blacksmith. He is also a prerequisite to the quest A Daedra's Best Friend.

When you first talk with him, he will ask you if you have seen a dog out on the roads and ask you to help catch him. If you agree, he will give you some fresh meat to help lure the dog in. As you follow the road out of town, you will eventually find the dog, who turns out to be Barbas, and can then start A Daedra's Best Friend.
