At one extremity of the spit was fastened a large circular box, or hollow wheel, something like the wire wheels which are so often appended to squirrel-cages; and in this wheel the Dog was accustomed to perform its daily task, by keeping it continually working. As the labour would be too great for a single Dog, it was usual to keep at least two animals for the purpose, and to make them relieve each other at regular intervals. The dogs were quite able to appreciate the lapse of time, and, if not relieved from their toils at the proper hour, would leap out of the wheel without orders, and force their companions to take their place, and complete their portion of the daily toil.
The dogs were also taken to church to serve as foot warmers. One story says that during service at a church in Bath, the Bishop of Gloucester gave a sermon and uttered the line "It was then that Ezekiel saw the wheel...". At the mention of the word "wheel" several turnspit dogs, who had been brought to church as foot warmers, ran for the door.
