The Brussels Griffon is square-proportioned, thickset and compact. It has good bone for its size. Its movement is a purposeful trot, with moderate reach and drive. In temperament it is full of self-importance, and its carriage reflects this attitude. Its almost human expression attracts attention and admirers. Its coat can be rough, with hard wiry hair — which is longer around the head — or smooth, with a short glossy coat.

The spunky Brussels griffon is full of itself, brimming with self-confidence and gusto. It is bold, playful, stubborn and mischievous. It is usually good with other dogs and pets. It tends to bark and climb, and some Brussels griffons can be escape artists. This breed makes a saucy companion for a family wanting an entertaining, sensitive pet.
