Dog Sunburn: How to Protect Your Pup and Treat Sun Damage

Most pet parents are surprised to learn that dogs can get sunburned, just like people can. If your dog has been spending time outdoors and you’ve noticed red, irritated, or peeling skin, sun damage may be to blame. Understanding how sunburn affects dogs — and what you can do about it — can make a real difference in your pup’s comfort and long-term health.

Common Causes

Dogs are more susceptible to sunburn than many owners realize, and certain factors can significantly increase your dog’s risk. While a thick, dark coat offers some natural protection, that protection isn’t universal or foolproof. Knowing what puts your dog at greater risk is the first step toward keeping them safe.

The most common reasons dogs develop sunburn include:

• Thin or light-colored coats: Dogs with short, fine, or white fur have far less natural protection against UV rays than their thicker- or darker-coated counterparts.
• Pink or lightly pigmented skin: Areas of skin with little to no pigment — such as around the nose, belly, and ear tips — are especially vulnerable to sun damage.
• Hairless or shaved areas: Dogs that have been recently groomed or shaved, or breeds like the Chinese Crested that naturally have little hair, are at a heightened risk.
• Extended outdoor exposure: Long afternoons at the beach, hiking trails, or even just lounging in the backyard during peak sun hours (typically 10 a.m. to 4 p.m.) can lead to overexposure.
• High-altitude environments: UV radiation is more intense at higher elevations, meaning dogs who spend time in mountainous areas face greater sun exposure than those at sea level.

Certain breeds — including Dalmatians, Boxers, Whippets, Bull Terriers, and American Pit Bull Terriers — are particularly prone to sun-related skin issues due to their coat and skin characteristics.

Symptoms to Watch For

Sunburn in dogs can range from mild irritation to more serious skin damage, and the signs can sometimes be easy to miss if you’re not looking closely. The areas most commonly affected include the nose, ear tips, belly, groin, and the skin around the lips and eyelids. If your dog has been in the sun and you notice any of the following, it’s worth taking a closer look:

• Redness or pink discoloration of the skin
• Skin that feels warm or tender to the touch
• Dry, flaky, or peeling skin
• Swelling, especially around the nose or ear edges
• Your dog scratching, licking, or rubbing at a specific area
• Hair loss in sun-exposed regions
• Blistering or crusty sores in more severe cases
• Whimpering or signs of pain when the affected area is touched

It’s worth noting that repeated sunburns over time can increase your dog’s risk of developing skin cancer, particularly squamous cell carcinoma. This makes early detection and prevention especially important for dogs with known risk factors.

What You Can Do at Home

If you suspect your dog has a mild sunburn, there are several steps you can take at home to soothe their discomfort and support healing. That said, it’s important to act gently and avoid anything that might further irritate already sensitive skin.

Move your dog out of the sun immediately. Bring them indoors or into a shaded area and allow them to rest somewhere cool and comfortable. This stops any ongoing damage and gives their skin a chance to begin recovering.

Apply a cool compress. A soft cloth soaked in cool (not cold) water can be gently held against the affected area for several minutes at a time. This helps reduce heat and provides some immediate relief. Avoid using ice directly on the skin, as this can cause additional irritation.

Use a pet-safe aloe vera gel. Pure aloe vera is a well-known, gentle skin soother that can help calm mild sunburn in dogs. Look for a product specifically formulated for pets, or check the ingredient list carefully — aloe vera products intended for humans often contain additives like alcohol, fragrances, or lidocaine, which can be harmful if your dog licks the area.

Keep the area clean and dry. Avoid letting your dog scratch or lick the sunburned skin, as this can introduce bacteria and delay healing. An e-collar may help if your dog can’t seem to leave the area alone.

Prevent future exposure. Going forward, apply a pet-safe, fragrance-free sunscreen with an SPF of 30 or higher to vulnerable areas before heading outdoors. Look for products specifically labeled for use on dogs, as human sunscreens often contain zinc oxide or other ingredients that are toxic to pets.

When to See a Vet

Mild sunburn can often be managed at home, but there are situations where veterinary attention is genuinely necessary. Don’t hesitate to call your vet if your dog’s symptoms seem more than superficial.

You should seek veterinary care if your dog is showing any of the following:

• Blistering, oozing, or open sores on the skin
• Significant swelling, especially around the face
• Signs of pain, restlessness, or behavioral changes
• Fever or lethargy alongside skin symptoms
• Skin changes that don’t improve within a day or two
• Any unusual growths, lesions, or discoloration that doesn’t resolve

Your vet may recommend prescription-strength topical treatments, oral medications to manage pain or inflammation, or further testing if they suspect more serious skin damage. If sun-related skin changes become a recurring issue, your vet can also help you develop a long-term sun protection plan tailored to your dog’s specific needs.

How Pet Insurance Can Help

Veterinary visits for skin conditions — especially those that require diagnostics, prescription medications, or follow-up appointments — can add up faster than most pet owners expect. Having a solid pet insurance policy in place means you can focus on getting your dog the care they need without the added stress of unexpected costs.
