Prostate gland is the accessory sex gland found in dog. The gland was collected from apparently healthy six sexually mature dogs. The prostate gland was bilobed exocrine gland. Histologically, the prostate gland consisted of stroma and parenchyma. The stroma consisted of capsule, septa and interstitial connective tissue. Parenchyma was enclosed by a thick capsule with outer thin fibrous and inner thick fibromuscular layer. The capsule contained blood vessels, myelinated nerve fibres and nerve ending like meissner’s corpuscle, pacinian corpuscle. Fibromuscular septa entered the parenchyma and divided it into lobes and lobules of different shapes and sizes. Paraenchyma of the prostate gland was consisted of glandular portion and collecting ducts. The gland was compound tubuloalveolar in type. Parenchyma of prostate gland was divided into lobules with many glandular follicles. The glandular follicles showed two zones namely outer and inner zones. The glandular follicles were lined by simple columnar epithelium with oval dark staining nucleus at the basal part and eosinophilic staining part apically. The duct system was ordered into tertiary, secondary and primary ducts. The secretory glandular portion entered into the tertiary duct, to secondary duct and finally to the primary duct. The primary duct then opened into prostratic sinus. The primary, secondary and tertiary collecting ducts and prostratic sinus were lined by simple cuboidal epithelium, simple cuboidal or columnar epithelium and stratified cuboidal epithelium. The prostatic urethra were lined by transitional epithelium.
