Ryan Flannigan of the Tampa Police Department's K-9 Unit wears a bite sleeve as Rick, a 4-year-old German shepherd, lunges at him during water training Tuesday at Adventure Island in Tampa. Rick, a military working dog, is handled by Air Force Staff Sgt. Johnny Hinojosa and is stationed at MacDill Air Force Base. Before Adventure Island drains its pools for the season, area law enforcement dogs and their handlers are allowed to train to search for criminals and missing persons around ponds, lakes, rivers and the bay.
