Kartagener's syndrome (KS) is a rare, congenital condition characterized by situs inversus, rhinosinusitis, and bronchiectasis. An underlying ciliary dysfunction (e.g., immotility or dyskinetic beating) produces most of the clinical signs seen in affected animals. This case report reviews the history, clinical signs, and diagnosis of KS in a male, long-haired dachshund. This is the first known report of KS, and thus primary ciliary dyskinesia, in this breed of dog.
