We love our dog park. It's large and has different elevations, good paths and different areas: open field, woods, meadow, paths. Small Dog Area, too. Oh, there are things that I would change, and occasionally (very occasionally) we have problem dogs come in and we have to break up fights that thankfully are more sound and fury than actually bloody. By and large it is a congenial community of caring dog lovers, so we all act protectively of our dogs. For instance, yesterday a very cute, very small wire haired (?) something with one blue eye and one brown, was tumbled painfully by two Rottie-mixes. I didn't wait for their owner to jump in, I did and rescued the little fellow and scolded the Rottie-mixes. When their mom caught up with me she wasn't angry, she thanked me. Yup, I used my Mom Voice, the "Do It or Else Voice" and it stopped them dead in their tracks.
Look, dog parks can be wonderful depending on the people that use them. I'm constantly asking people to read the rules posted at the gate. No puppies younger than 4 months (all shots), no aggressive dogs or dogs that can't be controlled; dog tags; current shots, etc., etc., Obligations to clean up after their pets and a suggestion (big one) that small children don't work well in a dog playground. Putting your 20 or 30 lb child down on the ground to wander around large, hurtling dogs is bad parenting 20-30 lbs against an 130 lb Corso running at 30 MPH. Bad Mistake! But, if everyone adheres to the rules, respects the other members and supports healthy play, it becomes a wonderful place. My dog loves it. It is her happy place.
I love my dog and my dog loves visiting her friends at the dog park. She has a reputation for kindness and often steps in to rescue smaller dogs being harassed. She loves the smaller pups. I didn't believe it at first, but other people told me about the times they've witnessed her settling an issue with more aggressive dogs. She gets in between and gives them the look..."run along." And then she turns and gives love to her little friend and they play. She's the best dog citizen that I know.
Personally, I love the dog park. I hope you find one as good as ours.
