Congratulations! I have said before that a CGC test is really minimal in terms of overall training, but I really didn't mean it like that! What I meant, and what I sternly stand behind, is that for some dogs a CGC is easy. For others, mine included, MOST of the test is really basic, but other "issues" can take a lot of time and effort to get through!
For my dog it was leash reactivity. By the time she was able to ignore other dogs walking by,, every other part of the test was "easy". So I felt that the test, overall, was too easy.
That being said, and as I tried hard to allude to earlier, it all depends on the dog. For some dogs, at the point of testing, it's an amazing feat to actually win that title! For others you might expect more or less or whatever!
Anyway, again congratulations! Hopefully you see that as a very very rudimentary beginning to "real" training! And I mean that whether or not you plan on sports or any other "formal" venue, which BTW I'm not much interested in myself, but either way keep working the dog and you'll see amazing benefits! Stop pressing the dog to learn new things, and you'll see things that you don't want and probably won't want to handle...
It's a GSD thing (lots of other breeds too, but it goes back to "DEAL WITH THE DOG IN FRONT OF YOU") Best of luck to you all, just keep challenging that brain! These dogs don't do well with neglect of any kind...
