Shiba Inu: Age, Food, Lifespan, and Health
Shiba Inus are ancient Japanese spitz-type companions. Independent, cat-like, and famously cleanliness-driven. Long-lived overall, with allergic skin disease as the most common concern.
Shiba Inu age in human years
Based on the Wang 2019 epigenetic-clock study and the AVMA aging ranges for small-class dogs. The first year of life equals about 15 human years on its own. The seven-year rule is wrong.
| Dog age | Human-year equivalent | Life stage |
|---|---|---|
| 1 year | 15 | adolescent |
| 2 years | 24 | adult |
| 5 years | 36 | adult |
| 8 years | 48 | mature |
| 10 years | 56 | senior |
| 16 years | 80 | geriatric |
