Well sorry, i looked on the internet for a dog breeder in southern MN. But i couldn't find any really, you could search on google if you'd like.
I know of a springer spanial, or brittany spanial, and they do breed some labs i know, but more brittanys, i could give you there name and number, but they are in Grand Rapids, MN.
Sorry i could not help you more.
