Under the ADA (28 C.F.R. § 36.302) and South Dakota Codified Laws § 20-13-23.2, a task-trained psychiatric service dog may accompany you in stores, restaurants, and other public places. Under DOT rules (14 C.F.R. Part 382), airlines must accept trained psychiatric service dogs in the cabin at no charge. The same task-trained dog is protected in housing under the federal Fair Housing Act: no pet deposits, no pet rent, no breed restrictions.
Under South Dakota Codified Laws § 22-35-9, presenting an untrained pet as a service animal is a Class 2 misdemeanor, punishable by up to 30 days in county jail or a $500 fine, or both, which is why our clinicians issue letters only after a real evaluation. If a business wrongly denies your task-trained service dog, file a complaint with the South Dakota Division of Human Rights or with the U.S. Department of Justice at ada.gov.
