When Does a Belgian Malinois Stop Growing?

The Belgian Malinois stops growing in height (target: 22–26 inches) around 15–24 months of age, but may continue adding weight toward 80 lbs for several more months. Males weigh 60 to 80 pounds, females 40 to 60 pounds. They should be lean, hard-muscled, and square in proportion. Any excess weight reduces their explosive athletic ability..

Early spay/neuter can affect growth plate closure, potentially resulting in a slightly taller but leaner adult.

Is My Belgian Malinois Overweight?

Assessing your Belgian Malinois's body condition (healthy range: 40–80 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 Belgian Malinoiss face higher risks of Hip Dysplasia, joint problems, and shortened lifespan. As a large-sized herding breed, maintaining lean body condition is especially important for longevity. Work with your vet to adjust feeding and exercise if needed.

Feeding Recommendation

Feed an adult Belgian Malinois approximately 0.6–1.6 cups of quality kibble daily, split into two meals. Males (40–80 lbs) may need slightly more than females (34–70 lbs). Males weigh 60 to 80 pounds, females 40 to 60 pounds. They should be lean, hard-muscled, and square in proportion. Any excess weight reduces their explosive athletic ability.. Active individuals with energy rated 5/5 may need portions at the higher end of guidelines.
