A Brussels Griffon may have either a smooth coat or a rough coat, depending on the breed. Whereas a rough-coated Brussels Griffon has no secondary name, a Brussels Griffon with a smooth coat is known as a Petit Brabancon.
The Brussels Griffon is a purebred dog that is in the toy group. They come in many different colors, including red, black and black and tan. Brussels Griffons often have a high-strung temperament and tend to be physically active. The wide set eyes and flat face of the breed gives them an unusual appearance that some people describe as looking like a monkey. They make good companions for those who have a lot of time to spend with their pets.
