In South Carolina, all animals that are adopted from a shelter of any kind must be spayed or neutered. If your dog is found and turned in to a rescue group, it won't be returned to you without being spayed or neutered.

There doesn't seem to be a way to enforce a law that requires all pets to be fixed. Who wants to be the watchdog and report the people who don't spay/neuter? Neighbors? Vets? We certainly don't want an enforcer coming to our front door asking if we have pets and wanting to see proof of sterlization.
