Belgian Malinois Weight Chart by Age

An adult male Belgian Malinois weighs 60.0–80.0 lb (27.2–36.3 kg) and an adult female 40.0–60.0 lb (18.1–27.2 kg), according to the American Kennel Club breed standard.

A male is typically 22.6–30.2 lb (10.3–13.7 kg) and a female 15.7–23.5 lb (7.1–10.7 kg) — around 38% of adult weight.

Roughly 30.7–40.9 lb for a male and 21.0–31.5 lb for a female, about 51% of the way to adult weight.

A male is usually 44.2–59.0 lb (20.1–26.7 kg) and a female 29.5–44.3 lb (13.4–20.1 kg).

56.5–75.3 lb for males and 37.5–56.2 lb for females — about 94% of final weight, with the rest filling in over the following months.

At 51% of adult weight by 4 months, a rough shortcut is to double a four-month weight. The calculator on the home page does this properly, using the growth curve for this size class and returning a range rather than one number.

Height is usually settled first; weight keeps filling in until around 18 months. The last 6% of adult weight takes roughly as long as the jump from 3 to 4 months.

Yes, and by enough to matter. Adult males run 60.0–80.0 lb (27.2–36.3 kg) against 40.0–60.0 lb (18.1–27.2 kg) for females. Comparing a female against a chart that does not separate the sexes will usually make her look underweight when she is not.

A large breed, defined by adult weight. That classification determines the growth curve used here: veterinary research shows dogs of similar adult size grow at similar rates regardless of breed.

Not necessarily. The table shows the middle of the healthy range, so plenty of healthy puppies sit below it. A puppy that is consistently below and not gaining, or that has dropped from a higher line to a lower one, is worth a vet visit. A single reading below the range is not.

Body condition tells you more than the scale. You should be able to feel the ribs under a thin layer of fat without pressing, see a waist from above, and see the belly tuck up from the side. A dog can sit inside the weight range and still carry too much fat.

Most published charts come from one breeder’s litters or from unsourced rules of thumb, and many do not say whether the figures are for males, females or both. The ranges here come from centile curves fitted to millions of veterinary bodyweight records, scaled to the AKC adult range, and split by sex.

The research behind these curves found neutering shifted growth trajectory only slightly, by less than the variation between individual dogs, so separate curves were not needed. Neutering is associated with a higher chance of becoming overweight in adulthood, which is a body condition question rather than a growth chart one.

An adult Belgian Malinois weighs 27.2–36.3 kg for males and 18.1–27.2 kg for females under the American Kennel Club standard. On the median growth curve a male is 10.3–13.7 kg at 3 months, 20.1–26.7 kg at 6 months and 25.6–34.2 kg at 12 months; a female 7.1–10.7 kg, 13.4–20.1 kg and 17.0–25.5 kg. Every row of the chart above gives kilograms under the pounds.

The American Kennel Club standard gives females 40.0–60.0 lb (18.1–27.2 kg). On the female growth curve a female Belgian Malinois is about 21.0–31.5 lb at 4 months, 29.5–44.3 lb at 6 months and 37.5–56.2 lb at 12 months, reaching adult weight at around 18 months. The Female column of the chart above gives every month.

The American Kennel Club standard gives males 60.0–80.0 lb (27.2–36.3 kg). On the male growth curve a male Belgian Malinois is about 30.7–40.9 lb at 4 months, 44.2–59.0 lb at 6 months and 56.5–75.3 lb at 12 months, reaching adult weight at around 18 months. The Male column of the chart above gives every month.
