We have no affiliation with PetScreening.com, but we do use their services and are generally very happy with the process.For pets, they collect photographs of the pet, as well as information on vaccination records and behavioral/bite history.For service animals, they verify the prescription with the healthcare provider.If nothing else, we can genuinely state (and document) that all applicants/tenants with pets, service animals, and/or emotional support animals are screened the same way and treated exactly the same based on a standardized set of industry-accepted criteria.
