One dog? I've seen and met a lot of GSD's. And you heard Renee, even another user on this forum had domineering problems on this forum during the adolescent years, which is where Rocky is. Renee said, that guardian breeds are headstrong. I've DEALT with that. I don't have a training instructor.. and you keep asking all these weird questions asking what the problem was that I had earlier, when it's FIXED. It was a simple question and for some reason you had so much trouble answering.
