From Animals in the News, one of 32 photos.  In this May 29, 2014, photo, self-taught horse trainer Martin Tata kisses his horse Milonga as he performs a demonstration for The Associated Press on a ranch in San Antonio de Areco, Argentina. There is no whip in sight, no shouting or loud jabs. Not even a firm hand on the reins. And yet Martin Tatta somehow persuades his beloved Milonga to join him in acrobatic feats, from handstands to other poses that even the most understanding horses rarely display.
