Brazilian Terrier Size
As a small breed, a Brazilian Terrier reaches its adult weight earlier than a large dog — smaller breeds finish growing sooner (Hawthorne et al., 2004).
Brazilian Terrier Lifespan
How long do Brazilian Terriers live?
The American Kennel Club publishes a life expectancy of 12–14 years for the Brazilian Terrier, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Brazilian Terrier can fall on either side of it.
Brazilian Terrier Growth Chart
What a Brazilian Terrier 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 10.0 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 Brazilian Terrier weigh?
A Brazilian Terrier weighs about 22 lb (10 kg) as an adult. That figure is the weight the American Kennel Club publishes in the breed's official standard, re-checked here every week — it is a typical weight across many adult dogs, not a target for one dog.
Is a Brazilian Terrier a small dog?
Yes — a Brazilian Terrier counts as a small breed, going by its published adult weight (10 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 Brazilian Terrier stop growing?
Earlier than a large dog. Hawthorne et al. (2004) measured that smaller breeds finish growing sooner, so a Brazilian Terrier 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 Brazilian Terriers still vary with sex, genetics, build and health, so read about 22 lb as the middle of a spread this source does not put numbers on. We don't invent the edges.
How long do Brazilian Terriers live?
The American Kennel Club publishes a life expectancy of 12–14 years for the breed, re-checked here every week. That is a figure for the breed, not a prediction for one dog: an individual Brazilian Terrier can fall on either side of it, and how a dog is fed, exercised and cared for moves the odds.
