Euthanasia decisions for companion animals are among the most difficult an owner faces. A welfare-centered framework helps ensure decisions serve the animal rather than delay suffering.
The availability of humane euthanasia is a significant welfare benefit for companion animals compared to human medicine, allowing suffering to be ended when treatment options are exhausted. However, this benefit is undermined when emotional difficulty of losing a pet leads owners to postpone the decision beyond the point where quality of life can be maintained. Systematic quality of life assessment using validated scales removes some of the subjectivity from the decision. Veterinarians have an ethical responsibility to raise the euthanasia discussion proactively rather than waiting for owner initiative when suffering is evident. The animal welfare principle of a good death is as important as the principle of a good life.
