We looovvveee the dog park around here! I can't even say it without three little tails wagging full speed. When we first took Franklin, he was extremely shy and wouldn't do anything but stay at my feet. We just went as often as we could and now he LOVES to play chase and run around with the other dogs. My advice is to keep bringing her there and eventually she will come out of her shell! It's so important for dogs to get social interaction... give it time and I'm sure she'll love it soon.
