Far too good looking to be a Quarter Horse! (Hides behind sofa from outraged QH owners!) I would have suggested Morgan, but if one of hers from the list above either a Sadlebred or a Tennesse Walker. Got some nice hoof boots on.
I would say its one of the TWH off the list. Looks too fine for a quarter horse, particularly the back end. Wonder if the horse is barefoot hence the boots
I was thinking it was probably just a safety thing, don't want your star get plastered to the paving and injured if the horse slips. Didn't occur to me about the barefoot thing
