Christi Smith planned to foster a 10-month-old pit bull named TaterTot until she could find him a permanent home. So just hours before he was scheduled to be euthanized, Christi brought Tater-Tot home. A few nights later, in the middle of the night,TaterTot started  barking, and running between Christi's room and her son's room.  Christi went to check on Peyton and he was barely breathing. In the emergency room the Doctor diagnosed Peyton with dangerously low blood sugar. Her son  could have died if not for the dogs persistence. TaterTot the HERO is now a permanent part of the Smith family.
