End of life decision-making for companion animals involves difficult welfare judgments about quality of life, suffering and the timing of euthanasia.
The capacity to choose euthanasia when an animal's quality of life has declined irreversibly is one of the most significant welfare advantages companion animals have over wild animals and livestock. The challenge is identifying the right moment — too early denies good days; too late prolongs unnecessary suffering. Validated quality-of-life assessment tools help owners and veterinarians make this judgment with greater clarity and confidence.
