Can Dogs Get Sunburn? The Surprising Truth About Sun Safety for Pets

Most pet owners know to protect themselves from the sun, but the question “Can dogs get sunburn?” is one that genuinely surprises many people. The short answer is yes, dogs absolutely can get sunburned, and the consequences go well beyond temporary redness. Dog sunburn is a real veterinary concern that can cause pain, skin damage, and in some cases, increase the risk of skin cancer over time. If you have a dog who loves the outdoors, this is one topic you’ll want to understand thoroughly. At Whitney Veterinary Hospital, we help pet owners in Peoria protect their dogs year-round, and we want you to have the information you need to keep your pup safe under the sun.

 

 

Do Dogs Really Get Sunburned?

Yes, dogs can and do get sunburned, and it happens more often than most pet owners realize. Just like human skin, canine skin can be damaged by ultraviolet radiation from the sun, and that damage occurs most readily in areas where the skin is less protected by fur or pigmentation. Dogs with short, thin, or sparse coats are at higher risk than heavily coated breeds, and areas of exposed or lightly pigmented skin are particularly vulnerable regardless of overall coat density.

Sunburn in dogs most commonly affects the nose, ear tips, belly, groin, areas around the eyes, and any spots where fur is naturally thin or absent. Light-colored or white-coated dogs are significantly more susceptible than darker-coated dogs because the melanin that gives fur and skin its darker color also provides some natural UV protection. Dogs who spend significant amounts of time outdoors during peak UV hours are at much greater risk than primarily indoor pets, making sun safety particularly relevant for active dogs.

Which Dogs Are Most at Risk for Sunburn?

While any dog can develop sunburn under the right conditions, certain dogs are significantly more vulnerable and require more proactive sun protection. Understanding which category your dog falls into helps you determine how much attention you need to pay to their sun exposure and what protective measures are most important.

Breeds and Coat Types at Higher Risk

• Dogs with white or very light-colored coats because their fur and skin contain less protective melanin
• Dalmatians
• White Bull Terriers
• Older dogs with thinning fur
• Boxers with white markings
• Dogs that have undergone shaving for medical or grooming reasons
• American Staffordshire Terriers
• Greyhounds
• Whippets
• Chinese Crested
• Hairless breeds such as the Xoloitzcuintli   

Environmental and Behavioral Factors

Beyond breed and coat type, a dog’s environment and daily habits play a significant role in their sun exposure risk. Dogs who spend hours outdoors during midday and early afternoon, when UV radiation is at its peak, accumulate significantly more UV exposure than dogs who are primarily active early in the morning or in the evening. Reflective surfaces such as light-colored concrete, sand, water, and snow can intensify UV exposure by bouncing rays back up toward a dog’s underside, which is why belly sunburn is actually quite common even in dogs with adequate back and side coverage. Dogs who love to sunbathe, lying on their backs with their belly exposed, are particularly susceptible to sunburn in that vulnerable area. Even on overcast days, up to 80 percent of UV rays can penetrate cloud cover, meaning cloudy conditions don’t eliminate the risk.

What Does Sunburn Look Like on a Dog?

Recognizing sunburn on a dog requires knowing what to look for, because the signs can be subtle at first and may appear several hours after the actual sun exposure occurred. The most obvious sign is redness or pink discoloration of the skin, which is most visible on areas with little to no fur such as the nose, belly, ear tips, and around the mouth. The affected skin may feel warm or hot to the touch, and your dog may react with sensitivity or discomfort when you gently press on the area.

More severe sunburn can cause the skin to blister, peel, or develop a dry, flaky texture, similar to what occurs with significant sunburn in people. Your dog may scratch, lick, or chew at sunburned areas in response to discomfort, which can introduce the risk of secondary infection if the skin barrier is broken. Repeated sunburn over time can lead to more lasting changes in the skin, including thickening, scarring, or the development of growths that may require veterinary evaluation. If you notice any of these signs on your dog after outdoor time, call Whitney Veterinary Hospital at (309) 685-4707 to discuss next steps.

Can Dog Sunburn Lead to Skin Cancer?

This is a question many dog owners haven’t thought to ask, but the answer is important. Repeated or severe sunburn in dogs can increase the risk of developing certain types of skin cancer, just as it does in people. Squamous cell carcinoma is one of the most common UV-related skin cancers seen in dogs, and it frequently develops in areas of chronic sun damage such as the nose, ear tips, and belly. Hemangiomas and hemangiosarcomas, particularly cutaneous hemangiosarcomas, are also associated with sun exposure and are seen more frequently in light-coated breeds and dogs with sun-damaged skin.

Catching any suspicious skin changes early is critical, because many of these conditions are much more treatable when identified in their early stages. This is one of the most compelling reasons to schedule regular wellness exams at Whitney Veterinary Hospital, where our team can assess your dog’s skin and flag any changes worth monitoring over time. If you notice a new growth, discoloration, or wound on your dog’s skin that doesn’t seem to be healing normally, please call (309) 685-4707.

How to Protect Your Dog From Sun Damage

The good news about canine sun safety is that there are practical and effective steps you can take to significantly reduce your dog’s risk of sunburn and the long-term damage it can cause. Sun protection for dogs has become an increasingly well-developed area of pet care, and your veterinarian is an excellent resource for personalized recommendations.

Dog-Safe Sunscreen and Protective Clothing

Sunscreen formulated specifically for dogs is available and can be applied to vulnerable areas such as the nose, ear tips, and belly before outdoor activities. It is critically important that you use only sunscreens designed for dogs or approved by your veterinarian, as many human sunscreens contain zinc oxide or PABA, both of which are toxic to dogs if ingested, and dogs inevitably lick their skin. Your veterinarian at Whitney Veterinary Hospital can recommend a safe and effective product.

Protective clothing designed for dogs, including rash guards, UV-blocking shirts, and belly bands, provides an excellent physical barrier against UV radiation and is particularly useful for hairless breeds, dogs recovering from procedures, or dogs who refuse to sit still long enough for sunscreen application. Hats and visors are also available for dogs and can help protect the nose and head area, though acceptance of headwear varies widely from dog to dog. A combination of behavioral management, timing of outdoor activities, and physical protection gives the most comprehensive sun safety coverage for at-risk dogs.

Managing Outdoor Time and Shade Access

Adjusting when and how long your dog spends outdoors is one of the simplest and most effective sun safety strategies available. Keeping outdoor time to early morning hours before 10 a.m. or evening hours after 4 p.m. significantly reduces UV exposure during the peak radiation window of the day. When outdoor time during peak hours is unavoidable, providing access to shaded areas is essential, and this means genuine shade from trees, shade structures, or buildings rather than a thin umbrella that doesn’t block reflected UV from the ground.

Keeping your dog on grass rather than reflective surfaces like concrete or sand further reduces the amount of UV radiation bouncing back toward their underside. Inside the home, keeping dogs away from prolonged direct sunlight through windows is also relevant, as glass does not block all UV radiation. Building these habits into your dog’s daily routine is especially worthwhile.

Protecting Your Dog Starts With the Right Knowledge

Dog sunburn is a real health risk that is entirely preventable with awareness and the right precautions. Whether your dog is a sun-loving Greyhound, a white-coated mixed breed, or simply a dog who loves spending long days at the park, knowing their risk level and taking appropriate steps makes a genuine difference in their long-term skin health. Regular veterinary wellness exams give your vet an opportunity to monitor your dog’s skin over time and catch any sun-related changes before they become serious problems.
