While looking through a book from the early 1900’s I found this article on a dog-powered well pump. Having read about the many uses of work dogs in the past, I believe this would work. Now unfortunately they don’t show a lot of details, but I am sure with a bit of work this could be connected to almost any hand or wind operated well pump.
DOG POWER FOR PUMP
This sketch shows an arrangement for making use of the dog for carrying water. It simply consists of a wheel 8 feet in diameter and 18 inches wide, with room enough inside for the dog to walk around, where he acts as a tread power, which causes the pump to revolve
In southern California there are a number of these dog-power pumps, which cost less than $15. A good-sized dog can easily earn his living in an arrangement of this kind.
