Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
Toy size brings kneecap, dental, and fracture risks that are typical for the size class, with limited breed-specific health data pointing to neither unusual hardiness nor unusual fragility.
A kneecap that slips out of its groove is common in toy breeds and ranges from an occasional skip to a limp that needs surgery.
Tiny jaws crowd the teeth, and baby teeth that fail to fall out can need extraction, so professional cleanings under anesthesia recur.
Very fine bones make leg fractures from jumps and falls a recognised risk that can mean surgical repair.
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 small, delicate frame combines with breed-linked patellar, cardiac, and airway issues that show up as recurring, sometimes surgical, vet expense.
A loose kneecap that slips out of its groove is common in tiny-boned toy breeds and can range from an occasional skip to a limp needing surgical repair.
Crowded, tiny jaws make Chihuahuas prone to early tartar buildup, retained baby teeth, and periodontal disease that often calls for professional cleanings under anesthesia.
Small dogs including this breed have a higher rate of degenerative mitral valve disease and occasional patent ductus arteriosus, which can mean lifelong cardiac monitoring and medication.
The breed's characteristic domed "apple head" skull is linked to a higher incidence of fluid buildup around the brain, which can require imaging and long-term neurologic management in affected puppies.
