Meet George the Great Dane and his little human buddy Bella. At only 43 pounds in the 5th grade, 11-year-old Bella's growth has been stunted by Morquio syndrome, a progressive bone disease. 131-pound George is her service animal, finally allowing her to ditch the crutches and wheelchair and move more freely around school (with George getting plenty of naps during class). He's gentle, smart, and almost big enough to salute the service dog at eye level.
