Out of a registered Quarter Horse, "Skippa Slice A Pie" and a mare that was 1/2 Quarter Horse and 1/2 Shetland pony, Dundee stands 13.5" tall, is stout, correct and has good hooves that are easily maintained. Dundee is easy to catch, easy to trim, loads well and gets along with every horse. Our 8 year old daughter has been riding him but some of our grandkids and some smaller adults have ridden him and gotten along great.
