When Does a Brussels Griffon Stop Growing?

As a small-sized toy breed from Belgium, the Brussels Griffon reaches full height of 7–10 inches by approximately 12–15 months. Full adult weight of 8–10 lbs follows within a few months as the dog fills out.

Nutrition during the growth phase is critical. Given the breed's predisposition to Patellar Luxation, proper growth-rate management is especially important.

Is My Brussels Griffon Overweight?

Assessing your Brussels Griffon's body condition (healthy range: 8–10 lbs):

  • Rib check: Run your hands along the ribcage—you should feel individual ribs under a slight fat layer
  • Overhead view: A defined waist should be visible between ribs and hips
  • Side profile: The abdomen should tuck upward behind the last rib

Overweight Brussels Griffons face higher risks of Patellar Luxation, joint problems, and shortened lifespan. Even for a small-sized breed, excess weight significantly impacts joint health and overall wellbeing. Work with your vet to adjust feeding and exercise if needed.

Feeding Recommendation

Daily food for an adult Brussels Griffon: 0.5–0.2 cups of high-quality dry food in two meals, budgeting $35–57/month. Puppies growing toward 8–10 lbs need three to four daily feedings until around six months old. Breeding challenges make them relatively rare and expensive. Their flat faces can cause breathing issues, and their prominent eyes are vulnerable to injury.—treats count toward daily calorie intake.
