Cutaneous lymphoma is a rare but significant skin cancer in dogs causing progressive welfare impacts that can be managed with appropriate treatment and quality of life monitoring.
Cutaneous lymphoma causes progressive skin discomfort from pruritus, ulceration and secondary infection. Oral involvement causes eating difficulty and pain. Welfare priorities include accurate diagnosis, appropriate systemic treatment to slow progression, management of pruritus with anti-inflammatory medications, prevention of secondary infections, and regular quality of life assessment to guide euthanasia timing.
