A 2-year-old Rottweiler dog was evaluated for cough, regurgitation, and nasal discharge, and was subsequently diagnosed with sinonasal aspergillosis and secondary esophageal disease. Following treatment of sinonasal aspergillosis, all clinical signs resolved. To the authors' knowledge, this is the first report of resolution of esophageal dysfunction following treatment of sinonasal aspergillosis.
