Brownie in the popular folklore of Scotland is a good-natured, invisible, household goblin that lives in farmhouses and other country dwellings. While the people are asleep, the Brownie performs their labors for them. If offered payment for his services, the Brownie disappears and is never seen again.
– Funk and Wagnalls Encyclopedia, 1996
My dog, Brownie, never did any chores. I even feed him every day and still nothing. However, he also didn’t disappear, so I guess I am good with his lack of work.
