Does PP&R actually do anything about off-leash dogs?

I work near a park that does not have an off-leash dog area. There are often many kids in the area and there has been a dog bite incident. I have contacted PP&R before and they simply said “when reported we will respond to any violations” which is incredibly unhelpful.

Outside of trusting in PP&R actually enforcing the off-leash codes, how can I annoy them until they do their job?
