Shih Tzu healthspan and longevity data

Primary cohort

What the population data measures

McMillan et al. analysed a large UK companion-dog dataset. For Shih Tzu, Supplementary Table S3 reports Kaplan–Meier median survival of 12.8 years from 17,901 breed records, including 5,894 deaths.

Use this number correctly

This is a UK population median, not a prediction for an individual dog, not life expectancy at birth and not evidence that a supplement extends life. The 95% confidence interval is 12.6–12.9 years.

Direct answer

How long does a Shih Tzu live in this UK cohort?

The recorded measure is 12.8 years. It is specific to this source population, not a death-date prediction or a promise that one intervention adds years.

Healthspan, not survival alone

More life is valuable when daily function is preserved.

The atlas keeps total survival separate from mobility, cognition, independence and chronic-care burden. This cohort supplies a longevity baseline; it does not supply a measured healthy-life duration for Shih Tzu.

MobilityTrack comfortable movement and meaningful change over time.

Cognition and behaviourNotice changes in engagement, sleep, orientation and routine.

Body conditionUse veterinarian-guided weight and nutrition planning rather than a generic supplement promise.

Disease burdenSeparate years alive from years requiring substantial chronic or supportive care.

Owner journey

Plan around life stage, not a disease search.

Baseline

Record weight, activity, appetite, mobility and relevant veterinary findings.

Protect function

Prioritise appropriate nutrition, healthy body condition and preventive follow-up.

Compare claims

Check whether an intervention was studied in dogs, another species or not at all.

PawCosts layer

Budget for healthy ageing, not just ownership.

The existing cost model will separate routine care, nutrition, screening, insurance, supportive care and optional products. Country defaults remain unavailable until a dated local source supports them.

Methods and review

How this profile is governed

Source data were imported from Supplementary Table S3 and mapped by exact normalized breed name or a recorded human-approved alias. Unsupported fuzzy matches fail closed. Medical review is not claimed because no reviewer sign-off is recorded for this page version.
