Dog Skin Tumours and Quality of Life

Skin tumours are the most common tumour type in dogs, with a wide range from benign to highly malignant requiring welfare-conscious decision-making about investigation and treatment.

Key Facts

Approximately one third of all tumours in dogs are skin-based
Many benign tumours (lipomas, sebaceous cysts) do not require treatment
Mast cell tumours are the most common malignant skin tumour in dogs
Early excision of malignant tumours dramatically improves prognosis
Quality of life is a central consideration in treatment planning for elderly dogs

Welfare Considerations

Skin tumours span a huge range from benign to life-limiting, requiring individual assessment of welfare implications of both treatment and non-treatment. Ensuring quality of life - freedom from pain, maintenance of normal activity - guides decision-making alongside clinical factors.

What You Can Do

Have any new lump investigated promptly by your vet
Do not assume lumps are harmless - early diagnosis improves outcomes for malignant tumours
Discuss quality-of-life considerations openly with your vet when planning treatment
Consider oncology referral for confirmed malignant skin tumours
Ensure pain management is part of any treatment or palliative care plan
