A parasitic skin disease known as
demodicosis is frequently found in dogs and is characterized by an excessive
number of Demodex mites on the skin’s surface and hair follicles. These mites
are obligate parasites and are part of the skin flora in small numbers of
healthy dogs. It can be transmitted directly from the mother to her offspring
through close contact 2-3 days after birth. These mites can be isolated from
the hair follicles of healthy dogs, especially on the face and nose area. These
mites spend their entire life cycle within their hosts and feed on skin cells,
sebum, and epidermal debris. However, they are found in much greater numbers in
the skin of sick animals. It is known that many factors affect the increase in
the number of mites. In generalized demodicosis in young dogs, any
immune-related changes play a crucial part in the pathogenesis. In older dogs,
demodicosis is observed due to immunity or immunosuppressive drugs used. On the
other hand, demodicosis occurring in young dogs may be genetic in origin and
more than one gene may play a role in the development of the disease.
Additionally, there are other unknown factors involved.
