Can Dogs Get a Sunburn and How I’ve Seen It Happen
I run a small mobile dog grooming van and spend most of my days outdoors, parked in driveways or along quiet streets. Over the years, I’ve seen more than a few dogs return from a sunny afternoon looking uncomfortable in ways most owners didn’t expect. The question comes up more often than you’d think. Can dogs actually get sunburned, or is that just something people assume? From what I’ve handled firsthand, the answer is pretty clear.
What Sunburn Looks Like on Dogs in Real Life
The first time I noticed it clearly was on a short-haired white terrier I groomed late one summer. The skin along his back looked pink and slightly swollen, and he flinched when I ran a brush lightly over the area. It wasn’t a rash or allergy. It was sunburn.
Dogs don’t show it the same way people do, and that’s where confusion starts. You won’t see peeling skin right away, and many dogs won’t scratch or react until it’s already irritated. In my experience, the most common signs are redness on the nose, ears, belly, or along the spine, especially in dogs with thin coats or light-colored fur.
I’ve handled 15-20 cases over the past few summers in which sun exposure was the clear cause. Most of those dogs spent three to five hours outside with little shade. That’s enough. It doesn’t take a full day at the beach.
Which Dogs Are More Likely to Burn
Some dogs are simply more at risk than others, and I’ve learned to spot them quickly the moment they step out of the owner’s door. Thin-coated breeds like Boxers and Dalmatians tend to burn faster, especially on their noses and ear tips. Hairless breeds are in a category of their own, and they require almost the same sun care as a person with very fair skin.
I always warn owners with light-colored dogs because pigment plays a big role here. A pale pink nose or sparse fur along the belly means less natural protection. I’ve even seen a golden retriever with a shaved summer cut come back slightly burned along the back where the coat had been trimmed too close.
There are also cases where medical conditions or age thin out a dog’s coat. A senior dog I groomed last year had patchy fur along his sides, and after one afternoon in the yard, those exposed areas turned noticeably red. That kind of sensitivity creeps up on people who have had the same dog for years without issues.
What I Tell Owners About Prevention
Most owners don’t think about sun protection until after something goes wrong. I usually bring it up casually during a grooming session if I notice risk factors. Shade matters more than people think, especially during peak hours between 11 a.m. and 3 p.m.
One thing I’ve suggested to a few regular clients is using pet-safe sunscreen, and I’ve seen decent results when applied properly before longer outdoor time. A client once asked where to start, and I pointed them toward a basic overview of dog sunscreen products to understand which ingredients are safe for pets. They came back a few weeks later, saying their dog seemed far more comfortable after long walks.
I also advise against shaving coats too short in summer unless there’s a specific reason. It sounds counterintuitive, but that layer of fur does offer protection. I’ve adjusted my grooming approach over time because of what I’ve seen. Now I leave a bit more length on certain dogs during the hotter months.

How Bad Can It Get If Ignored
Most mild sunburn cases I’ve seen heal within a couple of days with basic care, but a few have gone further. A bulldog I worked on for 1 year had blistering along the top of his back, and it clearly caused pain even during gentle handling. That dog had been left outside for most of a bright weekend.
Long-term exposure is where things get serious. Repeated sunburn can lead to skin damage that doesn’t fully recover, and in rare cases, it can increase the risk of skin tumors. I don’t throw that around lightly, but I’ve heard it directly from a local vet I trust.
Dogs won’t always show immediate discomfort. That’s part of the problem. By the time they start licking or avoiding touch, the damage is already there. It sneaks up on people.
What I Do When I Suspect a Burn
If I notice signs during a grooming session, I keep things simple and careful. I avoid hot water and switch to lukewarm rinses, and I skip any harsh shampoos that might irritate the skin further. Sometimes I’ll even stop a session early if the dog seems uncomfortable.
I’ll usually mention it directly to the owner and suggest they keep the dog out of direct sunlight for a few days. In a couple of cases, I’ve recommended a vet visit, especially if there’s swelling or signs of blistering. It’s not something to guess your way through.
I’ve learned to trust what I see with my hands. Skin tells you a lot if you pay attention. Warm, tender areas with slight redness are often the first clue, and once you know what that feels like, it’s hard to miss.
Most people assume dogs are naturally protected just because they have fur, but that only goes so far. After years of working outdoors with animals, I’ve stopped thinking of sunburn as rare. It’s just under-recognized. A little awareness goes a long way, and in my line of work, it’s made a noticeable difference in how comfortable the dogs are when they show up at my van.
