Frenchton Size
As a small breed, a Frenchton reaches its adult weight earlier than a large dog — smaller breeds finish growing sooner (Hawthorne et al., 2004).
Frenchton Growth Chart
What a Frenchton puppy weighs week by week, from the growth curve FEDIAF publishes (Nutritional Guidelines 2025, Table VII-8a) for a dog whose expected adult weight is 6.0 kg. It is an average, not a target, and it is only valid from 8 weeks to one year — FEDIAF notes that growth patterns show a certain individual variability. Read a row as the middle of a spread.

Common questions
How much does a full-grown Frenchton weigh?
A Frenchton weighs about 13 lb (6 kg) as an adult. That figure is the mass Wikidata publishes for the breed under a CC0 license, re-checked here every week — it is a typical weight across many adult dogs, not a target for one dog.
Is a Frenchton a small dog?
Yes — a Frenchton counts as a small breed, going by its published adult weight (6 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 Frenchton stop growing?
Earlier than a large dog. Hawthorne et al. (2004) measured that smaller breeds finish growing sooner, so a Frenchton reaches something close to its adult weight before a big breed would. 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 one weight instead of a range?
Because that is what the source publishes for this breed — a single adult mass, not a span. Real Frenchtons still vary with sex, genetics, build and health, so read about 13 lb as the middle of a spread this source does not put numbers on. We don't invent the edges.
