Ah, so a larger distance wouldn't guarantee a larger voltage, it would merely raise the chances because of changes to the surface being walked on.
Or, wait. No, the voltage difference is because one hoof is over electricity while the other hoof is over zero or fewer electricity, so now electricity will travel through the horse which is electrically conductive.

That's if we're wearing sneakers, right?
Like if one foot were barefoot and the other wearing a sock, we'd create a large difference in voltage?

There is less of a distance between a person's two feet than that of a horses front/back legs. Earth, the surface beneath our feet, typically has a high resistance. There is a higher chance "electricity" will choose to flow through a horse, as it has to either travel that distance through the horse, or through the ground. For a person, that distance is smaller, therefore less resistance, and less likely to use us a bridge between two spots on the ground.
