Cancer in Dogs: Causes and Symptoms

Cancer in dogs refers to the abnormal growth of cells that can form benign or malignant tumours. Several factors may contribute, including genetics, age, exposure to environmental agents, or chronic inflammation. Dog skin cancer is among the most common forms, including mast cell tumours and other skin-related cancers.

Clinical signs vary depending on the type of cancer, but common signs of cancer in dogs and symptoms of cancer in dogs include:

• Lumps or nodules on the skin that may change in size or appearance
• Loss of appetite, unexplained weight loss, or unusual fatigue
• Wounds that do not heal
• Discomfort, itching, or excessive licking of the affected area

At the first sign of an abnormality, a veterinary consultation is essential to establish an accurate diagnosis through biopsy, imaging, or laboratory testing, and to determine an appropriate treatment plan.

What Veterinary Treatments Are Available for Cancer?

Cancer treatment in dogs depends on the type of tumour, its stage, and the dog’s overall health. Therapeutic options may include:

• Medical treatments, such as targeted therapies and other cancer medications for dogs
• Surgery to remove the tumour when possible
• Radiation therapy or chemotherapy, depending on the protocol recommended by the veterinarian
• Supportive care to improve comfort and quality of life

Treatments may be administered orally, by injection, or in a clinical setting, depending on the nature of the cancer. Close monitoring is essential to adjust dosages, assess treatment response, and manage potential side effects.

How can I recognize skin cancer in dogs?

Any unusual lump, a mass that changes in shape, a persistent wound, or an irritated area that does not heal should be evaluated by a veterinarian. Only a biopsy can confirm whether a tumour is cancerous.

Can cancer be prevented in dogs?

There is no guaranteed prevention, but early detection significantly improves outcomes. Annual or semi-annual veterinary exams, especially for senior dogs, are strongly recommended.

Are cancer treatments safe for dogs?

Yes, when administered under veterinary supervision. Dosages are carefully adjusted for each dog, and regular follow-up allows monitoring of side effects and treatment effectiveness.

When should I consult a veterinarian?

As soon as you notice a lump, skin mass, unexplained weight loss, or any unusual change in your dog’s behaviour or appearance. Early intervention leads to a better prognosis.
