Diego is his name and his main duty is to protect the endangered rhinos from hunters who are looking for ivory.
The dog is from the Ol Pejeta Conservatory in Kenya where the last male northern white rhino in the world is located. His name is Sudan.
Sudan is guarded by armed guards 24/7 and Diego also joined the crew to do this job. Diego can actually run at speeds of 40mph.
