A guide horse?

Intelligence flourishes throughout the "Animal Kingdom," created there by the blind watchmaker, Mother Nature. We've all heard of guide dogs for the blind. Today I learned of guide horses. There's even The Guide Horse Foundation.

I learned about guide horses from Karen Pryor's wonderful 2009 book, Reaching the Animal Mind: Clicker Training and What It Teaches Us about All Animals:

Well, of course the polar bear needs a brain. It's a predator; it has to outwit its prey. Some people maintain that prey animals, therefore, such as cattle, horses, and sheep, have no need for this level of adaptability...Horse trainers, particularly, love this piece of sophistry. Since horses are prey animals, the theory goes, they can't learn from being given food; avoiding danger is the only thing they can really understand....
    People are clicker-training horses all over the world now....
    Miniature horses are a special breed...Miniature horses live a lot longer than dogs. Once trained, a guide dog has six or seven years left before it is too old to work. The owner of a guide horse, however, can expect to enjoy the services of this faithful animal for twenty years or more.
    The guide horse I know personally is a black-and-white mare named Panda. She belongs to Ann Edy, a college professor in New York State who has been blind since birth.
