It sure didn’t take long for this dog to become part of the family. TaterTot, a pit bull, was adopted by Christi Smith just hours before he was to be put down and the dog quickly proved to be a worthy companion. Just four days after she brought him home, the dog began running between Christi’s room and her son Peyton Anderson’s room, barking and whimpering to let the mom know something was wrong with her child. When Christi went to check on her 4-year-old, the boy was barely breathing. She immediately rushed him to the emergency room and doctors discovered his blood sugar levels were dangerously low. They were able to stabilize him. Watch here!
