Euthanasia decisions are among the most difficult in companion animal welfare. Evidence-based quality of life assessment helps owners and vets make decisions that serve animal interests.
Companion animal euthanasia welfare requires centring the animal's experience rather than the owner's emotional needs. The greatest welfare risk is delayed euthanasia - allowing animals to suffer because owners cannot accept their loss. Veterinary support in these conversations, including clear communication about quality of life indicators and what dying naturally looks like for the condition in question, helps owners make decisions that serve their animal's interests. Euthanasia when quality of life is poor is not giving up - it is the final act of care.
