This is a simple explanation of the Czech evaluation system for working line German Shepherds. The Czech Republic uses a system similar to that used by the East Germans (1950-1990) for evaluating their working line German Shepherds. The Czech system uses a series of letters and numbers to identify the various characteristics found during the evaluation of a particular German Shepherd dog. The following is a translation of the Czech "Bonitacni Karta", or Survey Card. These codes have been valid in the Czech Republic since 1990.
