Belgian Malinois weight and size chart
Numbers on a chart are a general guide, not a target to hit exactly — individual size varies with line, sex and genetics. Still, having a rough reference is useful for tracking whether a puppy is growing at a reasonable rate, and for knowing what "average adult size" actually means for this breed.
Adult size, by sex
| Height (at shoulder) | Weight | |
|---|---|---|
| Males | 24–26 in (61–66 cm) | 60–80 lb (27–36 kg) |
| Females | 22–24 in (56–61 cm) | 40–60 lb (18–27 kg) |
Working-line dogs bred for sport or service tend to run toward the leaner, more athletic end of this range; some show-line dogs are bred slightly heavier-boned. Both are within normal for the breed.
Puppy growth, by age (approximate)
| Age | Typical weight range |
|---|---|
| 8 weeks | 10–15 lb (4.5–7 kg) |
| 3 months | 20–30 lb (9–14 kg) |
| 6 months | 35–50 lb (16–23 kg) |
| 9 months | 45–65 lb (20–29 kg) |
| 12 months | 50–70 lb (23–32 kg), close to adult height |
| 18–24 months | full adult weight and muscle maturity |
Malinois typically reach most of their adult height by around 12 months but continue filling out with muscle and chest depth until 18–24 months — a "finished" adult look takes longer than it might appear from height alone.
What matters more than the number on the scale
Body condition — how the weight actually looks and feels on the individual dog — is a better guide than any chart. You should be able to feel ribs easily under a light layer of fat, see a visible waist when viewed from above, and see a slight abdominal tuck from the side. Two dogs at the same weight can look and feel very different depending on frame size and muscle mass, which is exactly why the chart above is a starting point, not a rule. See our piece on what to actually feed a Belgian Malinois for how to adjust portions based on body condition rather than the chart alone.
When a dog is well outside these ranges
A puppy growing unusually fast or slow, or an adult significantly outside the typical range in either direction, is worth discussing with a vet — not because the chart is a hard rule, but because it can be an early signal worth investigating, whether that's a nutrition adjustment or, less commonly, an underlying health issue.
