Lymphoma is one of the most common cancers in dogs, and treatment decisions involve complex trade-offs between extending survival, maintaining quality of life, and managing treatment-related side effects.
Treatment decisions for canine lymphoma require honest welfare assessment. CHOP chemotherapy can extend life significantly, and most dogs tolerate it better than humans do — nausea and lethargy occur but are manageable. Quality of life during remission can be excellent. However, when remission fails or side effects accumulate, continuing aggressive treatment may prioritize length of life over quality. Palliative approaches — using prednisone alone or with single-agent chemotherapy — maintain comfort longer in some cases. The welfare-centered approach involves regular quality-of-life scoring, honest communication with veterinary oncologists about treatment goals, and willingness to transition to hospice care when treatment burden outweighs benefit.
