Black hair follicular dysplasia in a Brazilian Terrier: a case report

Abstract

Black hair follicular dysplasia (BHFD) is a rare genetic disease in dogs. A black and white female Brazilian Terrier (one year and three months old) was referred with a history of progressive hair loss only in black hair areas. Following anamnesis, clinical examination, trichographic analysis of hairs and histopathological examination of skin fragments, the animal was diagnosed with BHFD. This report describes for the first time a case of BHFD in a pure bred Brazilian Terrier.
