By Dr. Duncan Houston BVSc

🌊 Introduction: Cancer Is More Common Than You Think

Cancer is one of the leading causes of death in dogs over 10 years old. But with early detection and modern treatment, many dogs live long, happy lives after diagnosis. As a veterinarian, I guide families through recognizing signs, understanding types of cancer, and choosing the right treatments. 🐾

In this guide:

• ✅ Early warning signs of cancer in dogs
• 💉 Most common types of dog cancer
• 🚀 Vet-approved treatment plans and support tools

1. Signs of Cancer in Dogs ⚠️

• 📦 Lumps, bumps, or swelling that doesn’t go away
• 🥣 Loss of appetite or sudden weight loss
• 😴 Lethargy or decreased interest in play
• 🤢 Chronic vomiting, diarrhea, or coughing
• 📆 Difficulty urinating, breathing, or persistent limping

Not all masses are cancer—but any change should be checked promptly by a vet. 

2. Common Types of Cancer in Dogs 📊

• Lymphoma: Cancer of the lymph nodes or immune system
• Mast cell tumors: Skin tumors that may look like warts or pimples
• Osteosarcoma: Bone cancer, more common in large breeds
• Hemangiosarcoma: Blood vessel cancer, often affecting the spleen
• Melanoma: Oral or skin tumors, often pigmented

Biopsy is the gold standard for diagnosis. Ask A Vet can help guide lab options and results interpretation.

3. Treatment Options for Dogs With Cancer 💊

• 🩺 Surgery to remove tumors or affected tissues
• 💉 Chemotherapy (oral or injectable), depending on cancer type
• 🧴 Palliative care: pain management, appetite boosters, and anti-nausea meds

Response varies—many dogs tolerate treatment better than expected, appetite and comfort level.
