Decisions about the timing and manner of companion animal euthanasia are among the most ethically complex in veterinary practice; quality-of-life frameworks help owners and vets navigate these decisions.
The availability of humane euthanasia for companion animals is one of the most significant welfare advantages they have over wild and farm animals. However, this option is only welfare-positive when used at the appropriate time — neither too soon, denying good-quality life, nor too late, prolonging suffering. Quality-of-life assessment tools provide a structured approach to decision-making that reduces the emotional difficulty of reaching the decision to euthanise without creating decision paralysis.
