Cancer is the leading cause of death in dogs over 10 years old and welfare-focused management can significantly improve quality of life throughout treatment.
Cancer in dogs creates complex welfare decisions for owners and veterinarians. The goal of treatment is not cure but quality of life maintenance, a distinction that shapes the approach to therapy. Dogs with cancer experience pain, fatigue, nausea, and reduced appetite that require active management. Regular quality of life assessment using validated tools helps identify when treatment is improving or compromising welfare. Palliative care focused on comfort rather than tumor control is an appropriate and compassionate option. Honest discussions about prognosis and welfare support owners through difficult decisions.
