We have small dog parks in our area. With that being said, sometimes the "small" dogs are a little too big. I would just be cautious and if you feel unsettled you can just leave. It's great for dogs

Bandit didn't go until he was a little over 1, Nala went right after she had all her shots. She is socialized much better, but that's not solely attributed to the dog park- we learned a lot with the second dog

Dog parks are a def plus
