Worked Clinical Example

Scenario
A Medium dog living 13 years with average food, routine vet care, and standard pet insurance.
Mathematical Calculation
Initial Setup ($1,800) + Annual Cost ($1,950 * 13 yrs = $25,350) + Senior Medical Cushion ($2,500) = $29,700.
Veterinary Interpretation
Estimated Total Lifetime Ownership Cost: $29,700 (~$190 / month average).
