When you see the letters "ZVJS" after a German Shepherd's name, it indicates that the dog has been certified by the Zuchtverband für Jagdspitze und Schnauzer as meeting the breed standards. This is a prestigious honor, as the ZVJS is a highly respected organization in the dog breeding world.
If you are looking for a German Shepherd that meets the highest standards of the breed, then you should look for one with the ZVJS certification. These dogs are typically healthy, well-bred, and have excellent temperaments.
