A pet that is not on a leash shall be removed by the owner or may be removed by a professional animal officer or handler at the expense of the owner. Except for service animals for the physically impaired, a pet may be restricted from any State museum property at the discretion of the museum director. Pets and animals that are part of a demonstration or public event may be allowed with the express permission of the museum director.
