Transylvanian hound Size
As a large breed, a Transylvanian hound 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.
Transylvanian hound Lifespan
How long do Transylvanian Hounds live?
The American Kennel Club publishes a life expectancy of 10–14 years for the Transylvanian hound, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Transylvanian hound can fall on either side of it.
Transylvanian hound Growth Chart
What a Transylvanian hound 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 25.0 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 Transylvanian hound weigh?
A Transylvanian hound weighs about 55 lb (25 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 Transylvanian hound a large dog?
Yes — a Transylvanian hound counts as a large breed, going by its published adult weight (25 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 Transylvanian hound stop growing?
Later than a small dog. Hawthorne et al. (2004) measured that larger breeds keep gaining weight for longer, so a Transylvanian hound 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 one weight instead of a range?
Because that is what the source publishes for this breed — a single adult mass, not a span. Real Transylvanian hounds still vary with sex, genetics, build and health, so read about 55 lb as the middle of a spread this source does not put numbers on. We don't invent the edges.
How long do Transylvanian Hounds live?
The American Kennel Club publishes a life expectancy of 10–14 years for the breed, re-checked here every week. That is a figure for the breed, not a prediction for one dog: an individual Transylvanian hound can fall on either side of it, and how a dog is fed, exercised and cared for moves the odds.
