Generalised demodicosis can be a very severe disease.
Localised demodicosis in juvenile dogs presents as patches of hair loss and red inflamed skin.
Records were reviewed for signalment, disease history, potential underlying aetiologies, diagnosed concurrent diseases, medications and demodicosis treatment.
