Turnspit dogs: the original rotisserie machines
Hundreds of dog breeds exist throughout the world, many bred for a specific purpose. Historically, Jack Russels hunted rats, Border Collies herded sheep, Greyhounds hunted hares and Alsatians were typically used as guard dogs. However, there a great many jobs that, for whatever reasons, humans no longer need to be performed and the breeds associated with those jobs go extinct as a result. The most famous example of this — the Turnspit dog.
