Canine lymphoma is one of the most common cancers in dogs, and thoughtful management balancing treatment efficacy with quality of life is central to good welfare outcomes.
Canine lymphoma welfare requires balancing the benefits of remission against the quality of life during treatment. Dogs in remission typically maintain good quality of life and owners often report that their dogs seem unaware they have cancer. Dogs who relapse or fail to achieve remission face progressive deterioration including swollen nodes, difficulty breathing if mediastinal involvement occurs, and fatigue. The welfare discussion in lymphoma management centres on individualised assessment of the dogs response to treatment and quality of life rather than pursuing maximum treatment intensity at the cost of comfort. Palliative care that prioritises comfort over survival time extension can be the most welfare-positive choice.
