You can watch the horses eat. The two bay horses (the darker ones) are mine. Blue is the alpha horse, and he arrives first. You may notice that Tude, one of the boarders and the last to arrive, has a pretty pronounced limp. He suffers from arthritis in a back leg, caused by an injury when he was young; he gets supplements (glucosamine) for that. Often, after a few minutes of activity, the limp will disappear.
Also notice there's only one of them hamming it up and posing for the camera: that would be Libby. The others are too interested in eating to look my way, but nothing stops my little ham from putting those ears up and looking pretty.
