Since he generally uses his bad foot for most of his digging, I often wondered (and still do) if he digs because the foot feels odd or is painful. Then I watched this video of wild donkeys digging watering holes in the desert and all the animals who make use of them:
....and it occurred to me that the Ramsey's three main holes are each at the farthest points in the pasture away from the water trough.
I use a track system to limit the amount of grass they have access to and to try to make them move around and get more exercise. There is one hole at each of the farthest corners of the track.
I still wonder if Ramsey uses his bad foot for digging because of odd nerve impulses inside the hoof or maybe he is just right handed, but I think I figured out why he is digging holes in the first place. If you are thirsty in the desert, dig a hole. Or find a donkey.
The rotten stinker has outsmarted my attempts to make them exercise. Although, I do have to admire the work and tenacity it takes to dig holes in this "soil".
I guess that explains why his toe is worn down at a funny angle.
