Dog Canine Mast Cell Tumour Welfare

Mast cell tumours are common in dogs and cause both primary suffering and treatment-related side effects requiring careful management.

Key Facts

Mast cell tumours are the most common malignant skin tumour in dogs
Boxers, Pugs, Bulldogs, and Labradors have elevated genetic risk
High-grade tumours can degranulate, causing systemic histamine reactions and shock
Surgery is curative for low-grade tumours if adequate margins are achieved
Novel targeted therapies including toceranib have extended survival in inoperable cases

Welfare Considerations

Dogs with mast cell tumours may suffer from both the tumour itself and from treatment side effects. Palliative care and quality of life assessment should guide decision-making alongside oncology protocols.

What You Can Do

Check your dog's skin monthly for new lumps and report changes to your vet
Discuss prognosis and quality of life honestly with your vet before starting treatment
Support veterinary oncology research into better-tolerated treatment options
