Adult males usually weigh 8–11 kg and females 7–9 kg. Most are close to their full size by around 17 months, though the last little bit of filling out takes longer. Growth reference: Salt et al. 2017, WALTHAM (6.5–9 kg band).

No Shiba Inu 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 14.6 y. Median survival across 514 UK dogs (VetCompass, McMillan 2024) · half live 11–17 y. How the later years go comes down to weight, teeth, exercise and regular check-ups far more than to the breed.
