Pick up after your pet. Make sure they are vetted
If you're not a dog owner, there is no reason be there. No kids. No glass. If your dog is bothering/bullying another dog, get his attention. No aggressive dogs. No cats. Please have all dogs vaccinated.
Keep an eye on your dog. Clean up after your dog. People won't tolerate aggressive behavior and Will let you know. Basically police yourself and be a good dog owner.
No children under 11 in the park
...and well socialized. Probably not being a responsible owner to bring a dog knowing it has aggressive tendencies.
No children allowed in the park either
