Cancer is the leading cause of death in dogs over 10 years. Welfare-centered cancer management balances treatment benefit against quality of life throughout the disease course.
Cancer welfare management in dogs requires honest assessment of treatment benefit versus burden at every stage. Aggressive treatment may extend life but at significant quality-of-life cost — chemotherapy side effects, frequent hospital visits, and ongoing discomfort. Dogs cannot express preferences or understand treatment rationale, placing the full ethical burden on owners and veterinarians. Welfare-centered cancer care includes robust pain management, honest prognosis discussion, regular quality-of-life assessment using validated tools, and willingness to shift from curative to palliative intent when disease progression warrants. The decision to pursue euthanasia before suffering becomes severe is a welfare-positive choice that deserves support without judgment.
