Turnspit dogs were in use until the middle of the 19th century as a tool to save cooks in large households the effort of turning meat on a spit by hand. The dog would be placed in a small wheel connected to the spit and as he ran the spit would be turned.

In order not to overexert a dog with this hot and unpleasant work they were often kept in pairs, so that they could be worked in shifts. It is believed that this is the origin of the proverb 'every dog has his day.'

'Whiskey' is the last surviving specimen of a turnspit dog, albeit stuffed. The breed appears to have died out with the advent of mechanisation in the kitchen.
