Some of the park rules you must adhere to include keeping your dog constrained in an enclosure or on a six-foot leash at all times. Cleaning up after your dog and disposing of your dog’s waste in the right manner and ensuring that your dog does not wander off into areas of the park that are prohibited to pets.
