The Queen rode Fell ponies in her last years. Most Fells are black but there are greys and they fade to white with age. Very hairy, legs, manes and tails. The Queen was a Patron of the Fells Pony Association along with the Cleveland Bay Horse Society. She bred both on her estates and allowed her stallions to be used by other breeders to keep the breeds going. She actually saved the Cleveland Bays from extinction by purchasing Mulgrave Supreme in the 1960s. He was headed for the USA when she stepped in to buy him. There were only four Purebred Cleveland stallions in the UK at the time.
A number of her ponies and horses work for the Crown in various tasks. The Bays are driven to carriages delivering dispatches to the Queen, bringing new Ambassadors to meet her. The Bays horse the other carriages seen hauling Royals to Ascot, in ceremonial parades. Other Cleveland Bays are in the Military as caisson horses, ridden mounts for the Artillery and other uses. There was a recent photo of the Queen petting a horse reaching towards her. It was a bay horse held by a Trooper. She was in a mint green hat and coat. Information said the horse was one she bred and gave to the Artillery, so horse likely remembered her from the farm! She was probably asking the Trooper how the horse was doing!! Ha ha
Lady Louise now drives Prince Phillip’s Fell Ponies. She has competed with them at the Royal Winsor Horse Show, been seen pleasure driving them on the Windsor grounds. She handles them very nicely.
The greys are called Windsor Greys, only used by the Queen to pull her carriages. They presently are a type, rather than a breed anymore. Often Irish Draft crosses.
The other various horses seen are often mixed breeding, purchased to fit the requirements of the troops. Color, size, level headed in stressful situations. They undergo continuous training to face the huge, noisy crowds, cannon fire, having to stand for long times. Again there is presently a large number of Irish Draft crossbreds for the size and bone needed, but other breeds are in the Military as well, TBs, Warmbloods.
The Queen may have also been Patron to other UK breeds, notably the New Forest, Exmoor, Highland ponies. The lesser known, rare breeds who still need help in getting their numbers up. She was Patron to many things.
