When Does a Belgian Sheepdog Stop Growing?

Belgian Sheepdogs typically reach their full adult height by 15 to 24 months and their full adult weight shortly after. This breed may continue to fill out and add muscle mass for several months after reaching full height.

Factors that influence when a Belgian Sheepdog stops growing include genetics, nutrition, and spay/neuter timing. Dogs that are spayed or neutered very early may grow slightly taller due to delayed growth plate closure.

Is My Belgian Sheepdog Overweight?

To determine if your Belgian Sheepdog is at a healthy weight:

  • Rib test: You should be able to feel the ribs without pressing hard, with a thin layer of fat covering them
  • Waist check: Viewed from above, there should be a visible waist behind the ribs
  • Tuck-up: From the side, the abdomen should tuck up behind the rib cage

If your Belgian Sheepdog is overweight, work with your veterinarian to develop a safe weight loss plan. Even a 10% reduction in body weight can significantly improve health outcomes.

Feeding Recommendation

Adult Belgian Sheepdogs typically need 0.7 to 1.5 cups of high-quality dry food per day, divided into two meals. Puppies need more frequent feedings — three to four times daily until six months, then twice daily. Always provide fresh water and adjust portions based on activity level and body condition.
