Ned Andrews is an author about whom I’ve been able to turn up remarkably little. He wrote one horse book, the ranch-based Little Stranger, which received a decent Kirkus review, which commented on its “sentiment without stickiness”.
Finding the book:not impossible to find; slightly easier in its UK printing.

Little Stranger, the Story of a Western Pony
William Morrow & Co, 1941, 248 pp, illus the author
Little Stranger is orphaned at four days old. Yaqui Bob, a dishonest worker on the Circle Bar Ranch finds the colt. Fred raises it, but he’s stolen by Yaqui Bob, who knows the colt is the son of Golden Girl,
a thoroughbred. Fred eventually recovers the colt, and is given him as a reward. The colt grows up, and Gred trains him so well he wins cowpony races, until once again Yaqui Bob causes trouble.
