Also known as demodectic mange or red mange. Small numbers of the demodex mite are normally found in the skin and ears of healthy dogs without causing any problems. Sometimes, however, the number of mites can suddenly increase and cause a disease called demodicosis, especially in young dogs.
Your dog might have demodicosis if it:
- Has bald patches on its face, especially around its eyes, and on its legs
- Has a rash
The dog rarely finds it itchy unless any of the patches get infected, so scratching may be unlikely. If left untreated, it can get more severe, spreading all over the body, and making the dog unwell. Demodicosis that develops in adult dogs can be a sign that the dog has an underlying illness.
