The hospital where Mena is staying had allowed patients in the past to invite their dogs to drop by as a way of lifting their spirits. Though Esquilador wasn't nearly as compact as a pup, his doctors thought the horse might be just whom Mena needed to see the most.
They soon realized how right they were.
Last week, on Mena's 65th birthday, friends transported Esquilador from his stable to the hospital, where nursing staff had arranged to have Mena meet him out front. And that's when everything changed.
