Perception of Dog Welfare in Veterinary Students: A Six-Year Study of Ethical Priorities, Cohort Variation, and Influencing Factors.

Veterinary students' perceptions of animal welfare are shaped by both educational exposure and individual background, with direct implications for future clinical decision-making. This study evaluated 157 ninth-semester veterinary students enrolled in a Deontology and Veterinary Legal course at the University of Las Palmas de Gran Canaria (Spain) across six academic years (2019/2020-2025/2026), excluding 2020/2021 due to pandemic-related teaching modifications. Participants completed a structured, previously published questionnaire assessing twelve common dog welfare issues on a 5-point Likert scale, subsequently grouped into five dog welfare dimensions. Students consistently prioritized overt and severe dog welfare concerns, including abuse or active cruelty, lack of treatment to prevent suffering, and malnutrition, while assigning lower importance to breed-related conditions and behavioral problems. Significant differences across academic years were identified for seven items and all dimensions, revealing temporal variability in dog welfare perception between cohorts. Gender and student background also influenced responses, with female and exchange students generally assigning higher scores to selected issues. These findings suggest that the perception of dog welfare is not static but varies between cohorts across academic years and is shaped by sociocultural factors. Strengthening veterinary curricula to address less visible and socially normalized dog welfare problems may be critical to ensuring comprehensive and ethically grounded professional practice.
