As a giant breed, a Rottweiler keeps growing for longer than a small dog — larger breeds reach their adult weight months later (Hawthorne et al., 2004). Expect steady growth well past the first year.

Common questions

How much does a full-grown Rottweiler weigh?

A Rottweiler weighs 93–110 lb (42–50 kg) as an adult. That range is the mass Wikidata publishes for the breed under a CC0 licence, re-checked here every week — it is a typical range across many adult dogs, not a target for one dog.

Is a Rottweiler a giant dog?

Yes — a Rottweiler counts as a giant breed, going by the middle of its adult weight range (42–50 kg). The cut-offs between small, medium, large and giant are a common veterinary convention rather than one official standard, so a breed near a boundary can be described either way elsewhere.

When does a Rottweiler stop growing?

Later than a small dog. Hawthorne et al. (2004) measured that larger breeds keep gaining weight for longer, so a Rottweiler is likely to fill out well past its first birthday. We don't publish a month-by-month figure, because no source gives one breed by breed — and an invented number would be worse than none.

Why is there a range instead of one weight?

Because the source publishes a range. Within any breed, weight varies with sex, genetics, build and health, and a mixed-breed dog usually falls between its parents' breeds. Narrowing 93–110 lb down to a single number would look more precise while being less true.

Breeds of a similar size

Weight varies within the Rottweiler by sex, genetics and health, and mixed-breed dogs fall between their parents. This is a typical range, not a guarantee.
