are dogs allowed in costco

Dogs are generally not allowed inside Costco stores due to health and hygiene concerns related to the presence of food. The only exception to this rule is for service dogs, which are permitted inside Costco in compliance with the Americans with Disabilities Act (ADA). Service dogs must be trained to assist individuals with disabilities, and Costco employees may ask limited questions to verify the dog’s status as a service animal. Emotional support animals and pets that are not service animals are not allowed inside Costco stores.
