Dartmoor Pony stallion Shilstone Rocks Snow Shoes. Dartmoor is originally a feral horse from south-western England. It's an old breed but during centuries it has been improved, most lately with Arabians and Welsh. They're quite small, 114-127 cm at withers and have usually a very good conformation. Accepted colors are bay/brown, black, chestnut, gray, and roan. Big white markings are not recommended, pinto coloring is not allowed at all.
