Euthanasia decisions for companion animals are among the most difficult welfare choices owners face. Evidence-based quality-of-life assessment helps guide compassionate decisions.
End-of-life decision-making for companion animals is complicated by profound human emotional attachment that can delay decisions past the point that serves the animal's welfare. The ethical principle is that euthanasia, when suffering cannot be adequately managed, is itself a welfare act — preventing prolonged dying that serves no purpose for the patient. Quality-of-life assessment tools provide structured frameworks for making these decisions more objectively: evaluating pain, appetite, hydration, hygiene, happiness, mobility, and good days versus bad days against a threshold for action. Veterinarians who communicate quality of life concerns clearly and compassionately support owners in making timely decisions. The concept of a "good death" — peaceful, pain-free, ideally in a familiar environment — is a welfare goal that home euthanasia services increasingly provide.
