Uggie's trainer from the Animal Savvy animal actor agency in Los Angeles recently announced the animal is being retired from feature films, but will continue to appear in short films and commercials.
Uggie took the stage with his co-stars when "The Artist" won Best Musical or Comedy Feature at the Golden Globe Awards last month.
