Abstract
Out of the 80 dermatitis cases studied in dogs, 17 were demodicosis cases. The affected
dogs belonged to two to six years of age group. Grossly, papules, pustules, nodules, alopecia,
scaly, crusty, hyperpigmented and thickened skin were observed. Adults and immature stages
were seen in skin scrapings. Neutrophils, lymphocytes and macrophages were seen in
cytological preparations along with mites. Histopathological changes included dilated hair
follicles with cross sections of demodex mites, hyperkeratosis, melanin pigment accumulation,
furnculosis and extrafollicular inflammatory changes.
