Preventive veterinary care delivers far greater welfare benefit per dollar than treatment of advanced disease. Understanding the welfare returns of prevention motivates sustained investment in companion animal health.
Preventive veterinary care is the single highest-return welfare investment available for companion animal owners. The welfare dividend calculation is clear: the cost of annual wellness visits and routine prevention is a fraction of the suffering caused by advanced disease and its treatment. A dog that develops advanced heartworm disease suffers from cardiac and pulmonary damage that could have been prevented with monthly medication costing less than a dollar per day. A cat with dental disease detected at a wellness visit suffers fewer months of chronic pain than one treated only when eating stops. The barrier to preventive care is primarily economic and educational, and programs that reduce both barriers — subsidized wellness visits, owner education — deliver measurable population-level welfare improvements.
