Welfare-centered approach to managing cancer in dogs, covering quality of life assessment, palliative care, treatment decision ethics, and supporting dogs and their owners through a cancer diagnosis.
Cancer in dogs confronts owners with the most difficult welfare decisions in companion animal care — when to treat aggressively, when to focus on palliation, and when to choose euthanasia. The welfare of cancer-bearing dogs depends fundamentally on effective pain management, nutritional support, and quality of life monitoring throughout the disease course. Treatment decisions must center the dog's experience rather than the owner's grief. Validated quality of life scales provide objective anchors for otherwise subjective assessments. Veterinary oncologists and palliative care specialists bring expertise in maximizing welfare across both curative and comfort-focused approaches. Euthanasia remains an act of profound welfare when cancer reaches a stage where quality of life cannot be adequately maintained.
