From Viv Hobbs
Debra Griffiths in her letter
(16 October, p 59)
seems sceptical as to whether dog treadmills could work.
They did, and were used in the “great houses” of the past to rotate the spits
on which meat was roasted. A working example survives at the Welsh Folk Museum
near Cardiff. I don’t remember whether the treadmill was angled so as to
convince the dog that it was approaching the meat, but such a temptation could
well have worked.
