Jazzy did fine at dog parks, she ignored the other dogs and it was simply a place where we could legally walk trails offleash.
I started taking Delgado at 6 months until he hit 9 months, he did very well 95% of the time. Was attacked once but no injuries thankfully, he was still intact however and by 9 months the dogs behaviour changed towards him. He lost his 'puppy license' and when they started treating him harsher he pushed back and I stopped taking him before something bad would happen.
I have no issues with certain parks, they can be a great source of exercise and fun for the dogs but you have to have the right dog and most GSD's don't fit that mold.
