The aim of the study was to evaluate histopathological changes in adrenal glands in dogs. 32 dogs (0.5–18 years of age) were examined during a routine autopsy. Dogs were divided into 3 age groups: young dogs (0.5–5 years, n=9), middle-age dogs (6–10 years, n=11) and old dogs (11 years and more, n=12). Morphological and histopathological examinations were performed. Percentage of adrenal glands pathology in dogs increased with age: the incidence of pathology in young dogs accounted for 22.3 % and in old dogs and more 91.7 %. Most common histopathological changes were: adrenal cortex hyperplasia (diffuse, nodular), atrophia, degeneration of z. fasciculata and z. reticularis, hyperemia. Also there were lymphocytic–plasmocytic inflammation, cortex adenomas, pheochromocytomas, cortex hemorrhagia, and cortex atrophy. Single cases of extramedulary haemopoesis, atherosclerosis and metastasis into adrenal gland capsule were identified.
