I’ve read about whorls and what they may mean in relation to their placing on a horses forehead. Whorls on other parts of the body also have meanings and the type and size are supposed to point to general characteristics too. Have you noticed if these seem true? I had a horse with two whorls above the eye line and he was a bit of a pill. Linda Tellington Jones had a book on whorls and nose types. I thought it was interesting.
The video is The Clever Cowgirl showing wild horses and her own stock and giving a run down on what the whorls could mean for each horse. Nothing to set your clock by, just interesting stuff that may or may not influence your next horse purchase.
