    "No dogs are allowed in the park except your dog. If it's your dog, it's fine. They should be kept on leash if necessary and always closely watched and cleaned up after them. Pro Tips: if your dog is not comfortable around children or other dogs,keep them on leash. The signs really say no dogs but it's not enforced and everyone clearly likes it that way."
