As advanced treatments are becoming increasingly feasible in veterinary medicine, the evaluation of the health-related quality of life (HRQOL) of treated animals is becoming more relevant. We evaluated owner-perceived HRQOL of 10 dogs that underwent craniotomy for meningioma resection between 2002 and 2022 at our institution through telephone interview. For this purpose, we developed a disease-specific questionnaire containing 52 items (mostly of scoring nature) patterned after previously validated instruments and organised into eight domains. Approval by the Human Ethical Committee and respondents' consent were obtained. We analysed the scores for all domains and dogs. The effect of different variables on the HRQOL score was determined via log-rank test and Pearson correlation. Scores for all included dogs (range, 0-235 points) were totaled, with a higher number of points indicating a better HRQOL. The dogs included in this study yielded a mean score of 200.6 points (range, 176-227 points), implying a good overall quality of life. There were no significant associations between individual parameters and outcomes. Our questionnaire represents a structured tool for the specific evaluation of postoperative HRQOL in dogs with meningioma, placing a minimal burden on respondents. Few instruments have been developed to assess animal welfare in a disease-specific context. Implementing these tools, however, is essential to accurately evaluate not only the impact of treatments on biologic parameters, but also their implications on patient welfare. Thus, treatment plans may consider HRQOL for a more comprehensive clinical decision-making process.
