Well, here’s a cheery scene. Laughing children, a bright fire, and … wait a minute, is that a dog on a treadmill?
Once common, turnspit dogs were specially bred to run on wheels and turn meat. Typically they were kept in pairs so they could take turns at the hot and unpleasant work, which largely went unappreciated. In Of English Dogs (1576) they’re described as “long-bodied, crooked-legged and ugly dogs, with a suspicious, unhappy look about them.”
Perhaps fortunately, the breed is extinct now, made obsolete by the mechanized kitchen.
