I have now had the pleasure of watching Sasha really get to play and enjoy herself with a couple of dogs (the first one a few months ago and then just earlier this week) and I noticed that she's kinda noisy when she plays. In fact, at first I thought she was getting angry, as she was growling or making some sort of similar noise, but her body language and really even the noise itself didn't sound like she was angry, and as I watched these interactions she never showed any aggression at all. She also barked some, mostly if the other dog was ignoring her and she wanted to play chase, but that was definitely her play bark (I've heard it directed toward me a couple of times, the bossy girl lol). I was just wondering if that was normal, if it was common for GSD's to be noisy when they played. My only point of reference is my golden and he was never noisy when he played with other dogs.
