Dogs are not allowed on all parts of the site (this is indicated by signs), but they are allowed on the site, provided they are kept on a lead. Other large animals (such as horses) are only allowed in consultation with the organization that grants written permission for this. All other animals such as birds of prey and pets (ferrets, etc.) are not allowed. In particular, the municipalities of Utrecht and Venlo strictly enforce the taking of animals that cannot be regarded as pets.
