'Saddest Dog' May Be Put Down After He's Returned to Shelter for Second Time

A lonely 2-year-old Labrador named Lana may be put down now that a second family has returned her to an animal shelter. Born the runt of her litter and always fighting for food, Lana never lost her defense issues. It's unclear why she was returned a second time but her first adoptive family returned her after she allegedly snapped at the mother.
