Pet insurance removes financial barriers to veterinary care, enabling owners to make treatment decisions based on animal welfare rather than cost constraints.
Pet insurance welfare operates through the mechanism of expanding treatment access — owners with financial barriers to care make different decisions than those without. The animal welfare consequences of inadequate veterinary access include delayed diagnosis, undertreated pain, and euthanasia for financial rather than welfare reasons. An animal euthanized because treatment cost is unaffordable when effective treatment exists is experiencing a welfare harm attributable to the financial barrier rather than medical necessity. Pet insurance shifts this equation by converting unknown catastrophic costs into manageable known premiums, enabling treatment decisions made on welfare grounds. The public health system would benefit from policies that expand pet insurance access.
