As of January 1st, 2012, the differences between KKL1 and KKL2 ratings were ended in favor of a universal breed worthiness test. Either the dog is breed worthy or not signified by KKL. The change was approved to promote functionality of dogs rather than just appearance. This new change makes KKL more difficult to achieve while leveling the playing field between “show” and “working” types, with more focus on the importance of functionality. This is a great step forward in returning the breed standard to its original, sturdier form, Kraftwerk’s standard from the beginning.
