There are actually three types of Griffons, the Belgian, Brussels Griffon, and Petit Brabancon. In some countries they are considered one breed, known as either the Belgian or Brussels, and in others each "type" is classified separately. Appearance Belgian Griffons are small dogs that weigh between 8-12 pounds and stand between 7-8 inches.
The Brussels griffon is a smart little dog, and therefore quite receptive to training. Like many small dogs, this breed may possess a feisty streak and it can be stubborn. Firm, consistent training can help your Brussels griffon become obedient and attentive. One aspect of training is to teach your griff to stop barking after giving you an alert.
