Overview
The Brussels Griffon is a toy companion famous for its almost human-like face, with large dark eyes and a whiskered, expressive muzzle. Small but full of character, it is a sensitive, devoted shadow to the people it loves.
Alert, curious, and affectionate, the Griffon bonds intensely and dislikes being left alone. It is intelligent and can be sensitive or stubborn, so it thrives with gentle handling and close involvement in family life.
History
Originating in Belgium as a stable ratter in Brussels, the breed was refined with toy spaniel and pug influence into a small companion dog. It gained wider fame and affection as a charming, characterful lap dog.

Temperament
The Griffon is devoted and people-focused, forming strong attachments and prone to separation anxiety. It is smart and lively, sometimes willful, and responds best to patient, positive training and plenty of companionship.
Health to watch
The short muzzle can affect breathing and heat tolerance; keep exertion moderate in warm weather.
Prominent eyes are prone to injury, ulcers, and cataracts; watch for redness, tearing, or squinting.
Kneecap slipping is common in toy breeds; lean weight and screening reduce strain and severity.
General breed tendencies, not a diagnosis. Every dog is an individual — pair this with regular veterinary care.
Care essentials
Griffons hate being alone; gradual training and company help prevent separation anxiety.
Protect this flat-faced breed from heat and guard its prominent eyes from injury and irritants.
Rough coats need weekly brushing and periodic stripping; smooth coats need only occasional grooming.
