Sunburn and Skin Cancer Risk in Dogs

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

We worry about our own sun exposure, but dogs need protection too.

Who is at risk

• White or light-colored dogs, such as white bulldogs, boxers and pit bulls
• Hairless or thin-coated breeds. See hairless dog skin care guide
• Dogs who sunbathe on their backs
• Recently shaved or clipped dogs
• Pink noses and ears
• Dogs in sunny climates or at high altitude

Signs of sunburn

• Red, tender skin
• Dry, cracked or peeling skin
• Curling ear edges
• Heat and pain
• Blisters in severe cases

Skin cancer risk

Repeated sun damage can contribute to tumors such as squamous cell carcinoma and hemangioma on lightly haired skin. Chronic sores, crusts or growths on the nose, ears, belly or flanks should be examined. See lumps and bumps on dogs and early signs of cancer in dogs.

What to do for sunburn

1. Move your dog out of the sun.
2. Apply cool compresses to the skin.
3. Call your vet for painful or blistered skin.
4. Do not apply human creams or aloe products without advice, since dogs may lick them.

Prevention

• Provide shade and water. See keeping dogs safe in hot weather.
• Avoid midday sun, when ultraviolet exposure peaks.
• Use dog-safe sunscreen on exposed skin, such as nose and ears, after checking with your vet. Avoid zinc oxide and products not labeled for pets if the dog may lick them.
• Protective clothing, such as UV-blocking shirts, for at-risk dogs.
• Do not shave to the skin unless advised. A coat offers some protection.

Heat and sun together

Sun exposure often comes with heat risk. See heatstroke in dogs.

Regular skin checks

Look at your dog's skin monthly, especially thin-haired areas. Part the hair and check for red patches, scabs, bumps or sores. Photograph changes.

When to see a vet

Book a visit for sores that do not heal, bleeding growths, scaly patches or rapidly changing lumps. Early removal improves outcomes for many skin tumors.

Common mistakes

• Assuming dogs do not burn.
• Using human sunscreen with unsafe ingredients.
• Over-shaving.
• Ignoring non-healing sores.

Troubleshooting

• My dog hates sunscreen: use shade and clothing.
• His nose is pink and peeling: ask about protection and check-ups.
• A sore on his belly will not heal: book a vet exam.

A simple plan

1. Provide shade.
2. Use safe protection.
3. Check skin monthly.
4. Test suspicious lesions.

Real-life examples

A white boxer with a pink nose uses shade and dog-safe sunscreen. A shaved golden retriever gets a belly burn and recovers with veterinary care. A white terrier with a non-healing ear sore has it biopsied. Early action helps.

Enjoying the outdoors safely

Sunny days can still be fun with a few precautions.

Shade and timing

Look for natural shade, use umbrellas or tents at the beach and schedule walks early or late. Check that hot surfaces such as sand and pavement are safe for paws. Remember that reflected light from water and sand increases exposure.

Protective clothing

UV-blocking dog shirts and hats can help hairless or thin-coated dogs. Make sure clothing fits well and does not restrict movement or trap heat. Choose lightweight fabrics, and take breaks in the shade with water.

After shaving or surgery

Shaved areas are vulnerable until hair regrows. Keep your dog out of strong sun, and ask your vet about safe protection for the area.

The takeaway

Protect light-skinned and thin-coated dogs from the sun. Have suspicious sores checked quickly.
