Definition of Follicular Dysplasia
Follicular dysplasia, also called canine recurrent flank alopecia, cyclic flank alopecia, color dilution alopecia, blue Doberman syndrome and black hair follicular dysplasia, is a general term for a non-inflammatory condition that involves abnormal development of hair follicles, which are the depressions in the skin that contain the roots from which hair grows. All forms of canine follicular dysplasia are considered to be hereditary; there are no other reported causes for this disorder. The effects of follicular dysplasia primarily involve hair loss and poor coat condition, which usually don’t seem to bother affected dogs. They are mainly cosmetic concerns for owners, unless the dog develops skin infections, irritation or sunburns from prolonged exposure to the elements. In most cases, dogs with this follicular dysplasia are born with a normal coat that gradually thins over time, especially on the underbelly and ear flaps.
