Dog Parks are not a held in high regard on this forum. I go when the park is empty and it is just my dogs. If you are worried about getting your puppy socialized do it with your friends who have dogs in a controlled environment where you can step and defend your pup when necessary. Or perhaps sign up for a puppy socialization class at a training club. It is great to start socialization young, but not at the cost of the puppy having bad experiences. Best of luck!
