There are smart dogs, and there are Einstein canines. Mia clearly belongs in the latter category. When a fire engulfed her family's home  in Greenville, S.C., the one-year-old Belgian Malinois opened four doors to make her way to the basement. There, she stood in a cool bathtub that quickly filled with water as firefighters doused the blaze. Mia's owners, Chris and Codi Brumby, were enjoying dinner out with their two children when they learned of the house fire. After six hours of intense heat, smoke and flames, they assumed Mia had not survived. When she was carried out by firefighters, she was soaked and bewildered, but completely unharmed.
