How mast cell tumours affect canine welfare, what treatment options exist and how owners can support their dog through the process.
A mast cell tumour diagnosis creates a trajectory of welfare impacts beyond the tumour itself. Surgical recovery involves wound discomfort; chemotherapy causes fatigue and gastrointestinal side effects; repeated oncology visits cause stress. However, quality of life during treatment is often maintained well with appropriate supportive care, and remission periods can be lengthy. Welfare assessment should track not only tumour response but also appetite, activity, sleep quality and social engagement. Owners need honest prognostic discussions to make decisions aligned with their dog's welfare rather than prolonging life at the expense of comfort.
