My dog's first day at the dog park. It reminded me of watching my child on a playground with other kids. You want your dog to be confident and friendly. Not too aggressive. Not too timid. She was nervous, and I got nervous watching her. She eventually found her group, other dogs with whom she felt comfortable. It seemed to me that she was shunned by the regular, cool dogs. My daughter thought I was overreacting and anthropomorphizing. I probably was, but watching the interactions certainly reminded me of kids on a playground.
