This particular dog park is a bar that opened down the street from where I live last fall. I actually like it a lot because it's a membership bar. You have to download an app, provide proof of your dog's vaccinations, and they have dedicated employees that pick up after the dogs, spray down the turf, and break up the occasional scuffle between pups. They also have a water park section where they turn on sprinklers for a few hours a day during the summer months. You can see that in the first pic above. My dog loves it. She'll stick her face in the sprinklers to drink water when she gets thirsty.
The app is nice too because it will tell you if your dog needs updated vaccinations. I meant to take my mom there a few months ago when she visited but the app quickly shut that down and let me know I needed to schedule a vet appointment before I brought her back.
The whole operation seems tailored to eliminate all the issues you run into at unregulated dog parks...people not picking up after dogs, aggressive dogs with passive owners (this place will ban dogs that repeatedly start fights), dogs that might not be vaccinated, etc. And there's lots of local craft beer on tap.
