Euthanasia for severe or treatment-refractory behaviour problems is a contested but sometimes welfare-justified decision requiring careful ethical consideration.
Behavioural euthanasia presents one of the most ethically complex decisions in companion animal medicine. The welfare of the dog, safety of humans and other animals, and resources available for long-term management must all be weighed. Premature decisions made without specialist input deny dogs opportunities for successful intervention. However, management of dangerous dogs in conditions that severely restrict their freedom and quality of life also raises welfare concerns. The ideal process includes board-certified behaviourist assessment, documented behaviour modification trials, honest quality of life evaluation for the dog, and clear safety risk assessment before any decision is made. Stigma around this topic prevents open professional dialogue that would improve outcomes.
