Most demodicosis occurs in young dogs under age one and a half. An older dog should not get demodicosis unless there is an underlying problem with the immune system. In such cases, demodicosis is considered an indication to seek a more serious hidden condition such as cancer, liver or kidney disease, or an immune-suppressive hormone imbalance.
Demodectic mange may occur in older dogs because the immune system often declines with age. Dogs who have a weakened immune system due to illness, malnutrition, or certain medications are also susceptible to demodectic mange.
31 lip 2024 · There are three forms of demodectic mange in dogs: localized form, juvenile-onset generalized form, and adult-onset generalized demodicosis.
Demodectic mange is a condition caused by excessive populations of a normal skin mite, Demodex canis. This mite is part of the normal microscopic community on the skin and is not normally a threat to health.
Three forms of demodicosis are seen in dogs: localized demodectic mange, juvenile-onset generalized demodicosis, and adult-onset generalized demodicosis. Localized demodicosis is seen in dogs usually <1 year old, and most of these cases resolve spontaneously.
In old dogs and cats, underlying immunosuppres-sive conditions contributing to demodicosis should be explored. Deep skin scrapings are the diagnostic gold stan-dard for demodicosis, but trichograms and tape squeeze preparations may also be useful under certain circumstances.
