Most Malteses reach their adult weight by around 9 months (40 weeks).
As a toy-sized breed, your Maltese reaches adult size by 8-10 months. Smaller breeds tend to reach full size faster than larger breeds.
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 Maltese's progress.

Because Malteses are a toy-sized breed, look for a small breed puppy food designed for their growth needs. Smaller kibble, higher calorie density.
Feed puppy-specific food until your Maltese reaches adult size (around 9 months), then transition to an adult formula over 7–10 days.

For a toy-sized breed like the Maltese, a 22-inch crate (fits dogs up to ~12 lbs) is the right adult size. Buy the adult size from the start and use the included divider panel while your puppy is still growing.
