Plain-English summary
Five dogs with breathing problems, including noisy breathing (stridor), hoarseness (dysphonia), and snoring, were found to have movable inflammatory masses in their larynx. The dogs underwent imaging tests that confirmed the presence of these masses, and a laryngeal endoscopy revealed two masses in each dog. All dogs had surgery to remove the masses, and none experienced any recurrence of symptoms during a follow-up period of about 13 months. The analysis of the tissue showed signs of chronic inflammation in the larynx, which is often seen in breeds with short noses that are prone to airway issues.

Abstract
Information on inflammatory laryngeal masses in dogs remains extremely limited. We aimed to describe the clinical and histopathological features and outcomes of five dogs with bilateral, movable inflammatory laryngeal masses. Stridor was a common clinical sign, followed by dysphonia and snoring, all of which were mild. The presence of movable masses was confirmed in all dogs through fluoroscopic or echolaryngographic evaluation. Laryngeal endoscopy identified two masses in each dog, consistent with everted laryngeal saccules. Surgical excision was performed in all dogs, and no recurrence was observed during a median follow-up of 13 months. Histopathological analysis revealed chronic laryngitis characterized by fibrosis, lymphoplasmacytic infiltration, edema, and lymphangiectasia, consistent with findings reported in laryngeal saccules associated with brachycephalic airway syndrome in dogs.
