What Are Cancer Moles on Dogs?
Cancer moles on dogs are abnormal skin growths that may indicate an underlying health issue.
While many lumps and bumps on dogs are harmless, some can signal more serious conditions like melanoma or mast cell tumors.
Benign moles, which are non-cancerous, are common in dogs as they age. These growths are usually small, stable, and painless.
However, malignant moles—those that are cancerous—can grow quickly, change in appearance, and cause discomfort.
Understanding the difference between benign and malignant growths is key to ensuring that your dog gets the care it needs as soon as possible.
Signs and Characteristics of Cancerous Moles on Dogs
Not all moles are created equal!
Here are some common signs that a mole could be cancerous:
1. Irregular Size and Shape
Cancerous moles often grow quickly or have uneven edges. If a mole changes size or shape over time, it’s a red flag.
2. Unusual Colors
Normal moles are usually consistent in color, but cancerous moles can appear dark, black, red, or even have multiple colors or uneven pigmentation.
3. Texture Changes
Watch for moles that become crusty or scabby. Cancerous moles on dogs can also bleed, ooze, or have ulceration and sores.
A mole that feels rough or changes texture is worth a vet visit.
4. Discomfort or Irritation
Cancerous moles can cause itching, pain, or swelling. It could be a sign of trouble if your dog scratches or licks the area frequently.

- Mouth: Oral melanoma is common, so check your dog’s gums and tongue.

How to Perform a Monthly Skin Check on Your Dog
Performing regular skin checks is an easy way to catch potential problems early.
Here’s a simple step-by-step guide:
- Feel for Lumps and Bumps. Run your hands over your dog’s entire body, noticing new or unusual growths.
- Inspect High-Risk Areas. Check the paws, mouth, abdomen, ears, and eyelids thoroughly.
- Document Changes. Take pictures and note any moles' size, shape, and color to track changes over time.
- Look for Discomfort. Notice if your dog seems sensitive or irritated when you touch certain spots.
Consistent with these checks can help you spot cancerous moles before they become a bigger problem.
What to Do If You Suspect a Cancer Mole
If you find a suspicious mole, don’t panic. Here’s what to do next:
1. Schedule a Vet Visit
A veterinarian will perform a thorough exam and may recommend a biopsy to determine if the mole is cancerous.
2. Be Prepared for Diagnostics
Tests like fine needle aspiration, imaging, or a full biopsy can help confirm the diagnosis.
3. Understand Treatment Options
If the mole is cancerous, treatment may include surgery, radiation, or chemotherapy.
Your vet will guide you through the best action based on your dog’s specific case.
