I was dissapointed in our local dog park.
There is a dog park in the next town over, (5 minutes away) but because I live in a different county they charge me extra to belong. I paid, I took my dog,I obeyed the rules. I rarely met anyone else who paid any attention to the rules. I also had to pick up left over other dogs' poop most of the time while I was there as evidently hardly anyone picks up after their dogs. My dog loves to eat other dogs poop and would grab a mouthful and run off like she had the best treat in the world, so that is how we got our exercise, sometimes she chases tennis balls, but most of the time, mommy chased her to get the nasty stuff out of her mouth
And hoped not to step in it while I wa chasing her! She would almost always get sick the next day or so.
People would also steal the special pooper scoopers that were supplied there.
On the one hand, it is great as it allows her to run free and yet protected by a fence. on the other, she would get sick, so I just figured it wasn't worth it in the long run.
Now that the local pet box store teaches classes, I think most people meet at the dog park and probably more pay attention to the rules. However, we no longer go, just in case.
I do wish folks would figure manners are also for dog parks
