Belgian Malinois puppies are one of the fastest-growing working breeds. Their growth is rapid during the first year, with major increases in weight, height, and muscle development.
At just 8 weeks, puppies weigh around 7–15 pounds, but by adulthood, they reach 60–80 pounds and stand 22–26 inches tall. Most of their height develops within the first 10–12 months, while full maturity occurs between 18–24 months.
Growth Timeline and Weekly Development
The fastest growth happens between 3 and 6 months, when puppies gain about 1–2 pounds per week. By 6 months, many puppies reach nearly 50% of their adult weight. At 9 months, they may reach 70–75% of full size, and after 12 months, growth slows as muscle mass increases.
