Nasal histological findings in asymptomatic control dogs and in dogs with chronic inflammatory rhinitis.

ABSTRACT: Chronic inflammatory rhinitis (CIR) is among the most common causes of chronic nasal signs in dogs. Despite research efforts, the etiology of CIR remains mostly undiscovered. The aim of our study was to describe the histological findings in nasal biopsies of control dogs without signs of nasal disease compared to dogs with CIR. The study groups were control dogs euthanized for reasons unrelated to this study (n = 20) and previously collected, archived nasal biopsies from dogs diagnosed with CIR (n = 20). A CIR diagnosis was based on clinical presentation, computed tomography, rhinoscopy, and histopathological findings indicative of CIR. Inflammatory cell counts and changes in the mucosal epithelium and associated lamina propria were evaluated from nasal biopsy specimens. The
