Shiba Inu

origin: Japan · 9 figures in the corpus · Q39315

Every figure below carries this breed's name or id in its source study -- grouped by what it measures, not ranked. A breed appearing under a study here does not mean every other breed was tested and came back negative; it means this is what has a named source so far. See each figure's own page for its caveats.

Longevity

14.6 years (median survival) verified

Shiba Inu: median survival age, UK veterinary clinic population

  • UK primary-care veterinary clinic population (VetCompass), not a census of all dogs of the breed.
  • Hazard ratio vs. the crossbred reference group: 0.45 (95% CI 0.37-0.55, p<0.001).

Size & head shape

1 size class (1=Small, 2=Medium, 3=Large) verified

Shiba Inu: body size class -- Small

  • Body size and cephalic index classification per Supplementary Table S5; for breeds absent from the study's primary source lists, assigned by majority agreement among Dogs Trust canine-behaviour experts rather than measured directly on dogs.
2 cephalic type (1=Brachycephalic, 2=Mesocephalic, 3=Dolichocephalic) verified

Shiba Inu: head-shape (cephalic index) classification -- Mesocephalic

  • Body size and cephalic index classification per Supplementary Table S5; for breeds absent from the study's primary source lists, assigned by majority agreement among Dogs Trust canine-behaviour experts rather than measured directly on dogs.

Group

1 group membership (see subject) verified

Shiba Inu: UK Kennel Club group: Utility; FCI group: Spitz and primitive types

  • KC/FCI group columns record nomenclature presence only, per the table's own caption -- the study did not use group as an analysis variable.

OFA (hip & elbow)

6.7 percent evaluated dysplastic preliminary

Shiba Inu: hip evaluations rated dysplastic (mild/moderate/severe combined), OFA cumulative statistics

  • OFA is a voluntary-submission registry: owners/breeders choose whether to have a dog evaluated and whether to submit the result, so this is not a random sample of the breed and most likely understates true population prevalence.
9.0 percent evaluated abnormal preliminary

Shiba Inu: elbow evaluations rated abnormal (grade 1-3 combined), OFA cumulative statistics

  • OFA is a voluntary-submission registry: owners/breeders choose whether to have a dog evaluated and whether to submit the result, so this is not a random sample of the breed and most likely understates true population prevalence.

Bite rate

11.242 bites per 1,000 licensed dogs preliminary

Shiba Inu: NYC bite reports per 1,000 licensed dogs of this breed, all years combined

  • One city only (NYC); breed labels are self-reported, not verified against a registry or genetic test.
  • Licensed-dog counts are active-license snapshots per extract year, not a true owned-dog population.

Other

1 purpose class: sled/draught verified

Shiba Inu: purpose class 'sled/draught', from FCI group: Spitz and primitive types

  • Registry group membership at time of the source table, not an independent behavioural assessment.
395 puppies registered verified

Japanese Shiba Inu (Utility group): UK Kennel Club new registrations, 2025; +25.8% vs 2016

  • UK-only; a breed with 0 or blank registrations in a year may be newly recognised, temporarily unregistered, or genuinely absent that year -- the source table does not distinguish these.
