Cancer is a leading cause of death in older dogs. Quality of life management during treatment and palliative care are key welfare priorities.
Cancer in dogs creates profound welfare decisions for owners and veterinarians. Treatment decisions must balance potential benefit against welfare costs of treatment side effects. Dogs experience treatment differently from humans - chemotherapy in dogs typically causes fewer and less severe side effects. Quality of life assessment throughout treatment allows adjustments that maintain acceptable welfare. When cure is not possible, excellent palliative care can provide meaningful quality of life.
