I have had a few people ask me what made the Pato horse so different from any other sabino roan. Several people suggested that the horse looked no different from horses like the one pictured to the left of this group. (That photo came from Notorious Stock, and can be seen in its entirety here.) I’ve set the horse from the previous post alongside him with a photo of a leopard appaloosa rump beside it. It is the organization of the spots on the pato horse into clusters, which are reminiscent of a leopard, that made me wonder if he was displaying a manchado pattern along with sabino. The horse caught my eye because he doesn’t look exactly like either a sabino roan or a leopard, but visually falls somewhat in between.
I also had someone say they had not seen a manchado that looked “anything like” a leopard complex horse. Here is another comparison shot.

It is the quantity of round spots set inside the white ground, often concentrated on the hindquarters, that gives the manchado pattern a leopard-like appearance. (Left is a manchado, right is an appaloosa. Photo used with permission.)
That’s not to say that sabinos cannot have round spots set within a white ground.

But it is unusual to see that concentrated on the top of the rump, and spread continuously over the whole horse. We don’t know that it is impossible, but the oddity of it made me suspect something else might be there.
