Many rules exist to avoid liability, particularly when regarding dogs. Private places often have these rules but don't enforce them, because they don't really care about the dogs. But, in case a dog does bite someone then they get to say it was the dog owner that wasn't responsible and that has to pay for damages. Many people don't know this and go around enforcing rules just for the sake of enforcement. But the rules actually exist to provide dog owners a way to let their dogs run free.
