Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
Hip, eye and seizure predispositions are real but not defining, and the small size keeps drug and procedure dosing costs moderate.
A loose or malformed hip joint that leads to arthritis and lameness, and in severe cases needs surgery.
An inherited (HSF4) clouding of the lens that can progress to vision loss and may need eye surgery.
Recurrent seizures with no other cause, seen in Australian Shepherd lines and managed with lifelong medication.
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.
Tune your metro ZIP, daily-care schedule, nutrition grade, and insurance deductible in the live actuarial engine.

Breed-average risk from a mix of manageable orthopedic and ocular conditions, plus a genetic drug-sensitivity mutation, without one dominant expensive syndrome.
A malformed hip joint that leads to arthritis in this active herding breed and can require lifelong management or surgery.
An inherited eye defect affecting retinal development that ranges from harmless to causing detachment and vision loss.
A neurological seizure disorder documented in the breed that often requires lifelong daily medication once diagnosed.
A genetic mutation carried by many herding-breed lines that causes dangerous reactions to certain common medications.
