Localised: Typically seen in dogs 3-6 months of age and 90% of cases will heal spontaneously. Signs are of a mild non- pruritic alopecia in some cases with erythema and a fine scale. Lesions are most commonly found on the head particularly around the periocular region and the forelimbs.

Localised demodicosis: Typically seen in dogs 3-6 months of age and 90% of cases will heal spontaneously. Signs are of a mild non- pruritic alopecia in some cases erythema and a fine scale. Lesions are most commonly found on the head particularly around the periocular region and the forelimbs.
Generalised demodicosis:
Most commonly occurs in dogs between 3-12 months of age. Can be widespread from the beginning and lesions can range from multiple poorly circumscribed areas of erythema, alopecia and scale to generalised pustules often resulting in rupture of the hair follicle (furunculosis).

A lymphadenopathy and pyrexia are also common features of generalised demodicosis. Pododemodicosis can occur with the generalised form, this manifests as erythema and secondary infection of the feet.
Adult Onset Demodicosis: Can present as generalised disease or focal alopecia . Onset in adulthood is often associated with inernal disease, immunosuppression or neoplasia. Long term use of glucocorticoids in the West Highland white terrier has been associated with adult onset demodicosis.
