Questions people ask

Adult males usually weigh 34–47.6 kg and females 24.9–40.8 kg. Most are close to their full size by around 16 months, though the last little bit of filling out takes longer. Growth reference: Salt et al. 2017, WALTHAM (30–40 kg band).
No Borzoi cycle figures are published here yet, so this is general guidance rather than a breed number: most females have a first season somewhere between six and fifteen months, and cycles then settle to roughly every 180 days. Smaller breeds tend to start earlier and larger ones later.
The median is 12 y. Median survival across 185 UK dogs (VetCompass, McMillan 2024) · half live 9–14 y. How the later years go comes down to weight, teeth, exercise and regular check-ups far more than to the breed.
