- 71–80 lb

- 32–36.5 kg

As a large breed, a Rhodesian Ridgeback 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 Rhodesian Ridgeback weigh?
A Rhodesian Ridgeback weighs 71–80 lb (32–36.5 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 Rhodesian Ridgeback a large dog?
Yes — a Rhodesian Ridgeback counts as a large breed, going by the middle of its adult weight range (32–36.5 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 Rhodesian Ridgeback stop growing?
Later than a small dog. Hawthorne et al. (2004) measured that larger breeds keep gaining weight for longer, so a Rhodesian Ridgeback 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 71–80 lb down to a single number would look more precise while being less true.

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