Annual veterinary examinations catch health problems before they cause significant suffering. Understanding what preventive care prevents makes the welfare case for regular examinations compelling.
Preventive healthcare is a welfare investment with high return: conditions caught early cause less suffering and are less costly to treat than the same conditions caught in advanced stages. A dog with dental disease detected at grade 2 (reversible with cleaning) suffers far less than one not detected until grade 4 (requiring multiple extractions and prolonged recovery). A dog with early kidney disease managed through diet suffers far less than one in renal crisis requiring hospitalization. The annual exam is the veterinary equivalent of welfare monitoring - the systematic check that catches what daily owner observation misses. Financial barriers to annual exams create a welfare inequality that affects companion animals in lower-income households disproportionately.
