Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
A sturdy, long-lived terrier whose main cost drivers are orthopedic issues and skin allergies rather than any single defining syndrome.
A kneecap that slips out of its groove, common in small terriers and ranging from a minor gait quirk to a condition needing surgical correction.
A degeneration of the hip's femoral head seen in small breeds during growth, usually resolved with corrective surgery in the affected leg.
Terriers with wire coats are prone to environmental and food allergies that cause chronic itching and repeat dermatology visits.
Terrier breeds carry an above-average predisposition to insulin-dependent diabetes, which requires lifelong monitoring and daily insulin once diagnosed.
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.
