I stopped training G&G 12 years ago and I know things changed by now. But with this manny members there must be someone out there who can answer your question. So people who train G&G .......... help supernova
The dogtraining club where I train at the moment has first puppy, beginners, advanced (those three have no national acknowledgement) Then you go to the officially GG0, GG1, GG2, GG3
With other Dog schools you have; GG A, GG B, GG O, GG 1, GG2, GG3 (All officially national)
