Mast cell tumors are the most common malignant skin tumor in dogs. Understanding treatment options and welfare considerations helps owners make informed decisions for affected dogs.
Mast cell tumors create welfare considerations at multiple levels. The tumors themselves can cause local discomfort, inflammation, and ulceration. Treatment side effects including surgery recovery, chemotherapy toxicity, and targeted therapy adverse effects require careful welfare monitoring. For high-grade disease with poor prognosis, the welfare calculus must balance treatment burden against quality time remaining. Owners and veterinarians must make difficult decisions weighing curative intent against palliative approaches that prioritize comfort.
