The Rattle Griffon is a terrier at heart, small but energetic and outgoing, curious about its surroundings, and endearingly affectionate with its owner.
It is a cross between the Brussels Griffon and the American Rat Terrier, which is considered by others not to be a breed but a type.
The Brussels Griffon, named after the city from which it comes, also shares breed characteristics with two other variants, the Griffon Belge and the Petit Brabancois. It started out as a barn rat catcher, and was gradually allowed into homes as a family pet. It is distinguishable by its “beard” and flat face with round, slightly bulging eyes.
The American Rat Terrier, closely similar to feists, small mixed-breed hunting dogs in southern US, is also an excellent ratter and used to hunt small prey above ground.
