Bushy-faced with an underslung chin, the toy sized dog has a fiery, excitable disposition.” (Nina Leen—Time & Life Pictures/Getty Images)
The Griffon Bruxellois originated from a small Belgian rough coated ratting dog, which descended from the Affenpinscher.
The first dogs are very hard to trace as affixes were not required either in Belgium or in the UK. This was mainly for the ‘well off’ dog owner. In Belgium it was only the members of the Societé Royal de St. Hubert (The Belgian Kennel Club) who had affixes and this was expensive. As most Belgian Griffon owners were working class they couldn’t afford affixes.
