I am a newbie as well. I never had a dog as a kid, and my two dogs are my first (we got them as puppies almost five years ago, which shows you how much we knew about raising dogs).
I would like to think that I have learned a few things about raising a puppy as far as house training, promoting good house manners and off leash behavior. I have also dealt with joint issues and have learned about HD and treatments for it with Rosa. My dogs have taken some agility and nosework classes, but I do not know enough on those topics to be helpful.
My male GSD has had a lot of training to help us control his reactivity and build his confidence. I have done a great deal of research about dog behavior and how to shape it. I generally only give advice in areas that I have personally dealt with successfully. Which is why I don't post here very often.
