Iron Mike is four feet tall and three feet wide, at its widest point. The fountain's lowest tier is a pool for pets and reads "Illinois Humane Society." There is a step for children on the south side of the fountain and on the north, street, side, the largest middle tier is made to be accessible to horses. On the rear side of the horse basin is a "bubbler" for adults, it is also reachable by children via the iron step.
