The cases that dog trainers and behavior consultants face are often traumatic and emotionally challenging, especially under pressure from distressed clients. This study investigated whether more years of professional experience and higher levels of dog aggression contribute to burnout and whether the overall emotional toll of caring moderates these relationships. Eighty-six professionals completed the Professional Quality of Life Measure, which evaluates the positive aspects of caregiving and negative outcomes such as burnout and secondary traumatic stress. The analysis revealed that neither extended work experience nor increased dog aggression significantly predicted higher burnout levels, and the anticipated moderating effect of emotional strain was not observed. The levels of burnout and secondary traumatic stress in this sample were similar to those reported in other animal-care and human healthcare settings, while the satisfaction derived from caregiving remained relatively high. These results suggest that factors beyond years of experience and dog aggression-such as workplace support and individual coping mechanisms-may be more crucial in influencing burnout among these professionals. This study highlights the need for an expanded investigation of other possible influences, such as workplace support and personal coping mechanisms. Identifying specific challenges that dog trainers face and implementing strategies to offset burnout will create a healthier and more sustainable work environment and improve the quality of life for humans and their canine companions.
