Most Belgian Malinoiss reach their adult weight by around 17 months (72 weeks).
As a large-sized breed, your Belgian Malinois reaches adult size by 14-18 months. Larger breeds have a longer growth phase. Feeding a large-breed-specific puppy food during this period supports proper bone and joint development.
Individual dogs may reach full size slightly earlier or later. Spayed or neutered puppies may also have slightly different growth timelines. Regular vet checkups are the best way to track your Belgian Malinois's progress.

Because Belgian Malinoiss are a large-sized breed, look for a large breed puppy formula designed for their growth needs. Controlled calcium and phosphorus for joint health.
Feed puppy-specific food until your Belgian Malinois reaches adult size (around 17 months), then transition to an adult formula over 7–10 days.
