American Pharoah: The 'alpha' individual of the horse world

(CNN)Everyone knows American Pharoah as the wonder-horse who charged to Triple Crown glory last year, but what is the thoroughbred like behind closed stable doors?

"Super intelligent and kind," according to John Hall, who looked after him in his younger days at Taylor Made Farm, near Nicholasville, Kentucky.
    He would go on to become the first horse to complete a clean sweep of the Kentucky Derby, Preakness and Belmont Stakes since 1978,.
    Hall says, wherever Americah Pharoah was, the thoroughbred "stood out" and was very much an "alpha" individual.
