End-of-life decisions for dogs are among the most difficult welfare responsibilities of ownership, and evidence-based approaches help owners make decisions that prioritize animal welfare over human emotional needs.
End-of-life decision-making for companion dogs requires centering the dog's experience rather than the human emotional response to the decision. The unique gift of companion animal euthanasia — preventing suffering rather than waiting for death to occur naturally — is often not used appropriately because owners delay to avoid the grief of loss. Studies consistently show that more owners report wishing they had acted sooner rather than later. The welfare-positive principle is that the dog's daily experience of quality — assessed honestly, not optimistically — should determine timing. A final week of suffering does not negate a lifetime of love; choosing the moment before suffering becomes severe is the highest act of care.
