German Shepherd vs Belgian Malinois: Size & Growth Compared
Updated October 2026
German Shepherds are the heavier, more substantial dog — typically 50–90 lb vs the Belgian Malinois at 40–80 lb. The Malinois is a leaner, lighter-boned athlete that often looks smaller than its weight suggests, while the Shepherd carries heavier bone and a thicker coat. Both mature around 18 months, but the Malinois tends to look “finished” a little earlier because there is less bulk to fill in.
