Assessing quality of life and making end-of-life decisions for companion animals is one of the most emotionally difficult aspects of pet ownership, with welfare implications for delayed euthanasia.
Prolonged suffering from uncontrolled pain, inability to perform basic functions, or advanced terminal disease causes significant welfare harm when euthanasia is delayed. Quality of life assessment tools help owners make more objective decisions. The gift of a peaceful death when quality of life is irreversibly poor is a profound act of welfare, and veterinary support for this decision is essential.
