The Brussels Griffin is a hard-headed breed of dwarf dog that is recognized all over the world. If you carefully study the physique of this breed, then the obvious similarities with the pug and the affenpinscher are very striking. The Brussels Griffin is actually a doggie, obliged to thank the pug and the Cavalier King Charles Spaniel for the birth. The short, monkey-like face was adopted from the energetic Cavalier King Charles Spaniel, and the pug gave the breed short hair.
