Queensland Police Commissioner Katarina Carroll and State Police Minister Mark Ryan have joined more than 100 spectators to unveil a new service monument to the state's past and present police dogs this morning.

The monument, located at the Brisbane Dog Squad HQ in the southwest suburb of Oxley, was surrounded by over a dozen named stones representing past service dogs.

The ceremony comes just nearly a month after Police Dog Rambo was killed while tracking wanted man Alan Lace in Maryborough.
