Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
A brachycephalic skull adds airway surgery and heat-emergency risk on top of recurring eye and dental treatment, which together lift the Shih Tzu above breed-average vet spend.
A short muzzle crowds the nostrils and soft palate, causing noisy breathing and heat intolerance; severe cases need corrective airway surgery.
Prominent eyes are easily scratched and often produce too few tears, so owners face lifelong drops and occasional emergency ulcer treatment.
A short jaw crowds the teeth, so plaque builds fast and leads to repeated anesthetic cleanings and extractions.
The kneecap slips out of its groove, causing a skipping gait; higher grades need surgical realignment.
Coat load, energy, and temperament shape boarding, grooming, and handling costs beyond the medical ledger.
Adjust the compounded annual CPI. Veterinary clinical services have trailed near +7.8% YoY; the pet-care basket sits lower.

A very high prevalence of early-onset mitral valve disease drives recurring cardiology cost well above typical toy-breed baselines.
This breed has an unusually high rate of early-onset heart valve degeneration that often needs lifelong cardiology monitoring and medication.
A neurological condition tied to skull shape that can cause pain and requires specialist imaging and management in affected dogs.
A common small-breed knee condition where the kneecap slips out of place, sometimes needing corrective surgery.
Long, low-set ears trap moisture and debris, making this breed prone to recurring ear infections that need routine cleaning and occasional treatment.
