 But officials with the shelter say there's more to this story. Crystal Odom of Darlington says she is devastated after her emotional support dog Lexi was surrendered to the Darlington County Humane Society by her sister during a time when she and her mother were ill and her sister received bad news about her own health. Odom's sister told Odom she took Lexi to the shelter for temporary help caring for the dog, but they were later told they could not be reunited with the German Shepherd mix.
