i dont know which association does it but they do put the CAO, CO, Tatra , etc...in one group without the shepherds...they have it this way:

the herding group: includes shepherds large to medium size GSD, Malinois, berger de brie, etc..

then they have the working group with larger dogs that are mostly guardians: CAO, CO, Tatra, anatolian shepherd, Cuvacz, ,,,,,
