Many dogs love nothing more than stretching out in a sunny spot for an afternoon nap. Whether they're dozing off in the garden, relaxing on the patio after a walk, or snoozing at the beach, lying in the sunshine can seem harmless.
However, just like people, dogs can get sunburned. Prolonged exposure to the sun especially during the hottest part of the day can damage their skin, cause discomfort, and in severe cases increase the risk of long-term skin problems.
In this guide, we'll explain how dogs get sunburned, which breeds are most at risk, how to recognise the signs, and simple ways to keep your dog safe while they rest outside.
Can Dogs Really Get Sunburned?
Yes. Although a dog's coat provides some protection from the sun, it doesn't completely block harmful UV rays.
Areas with little or no fur are particularly vulnerable, including:
- The nose
- Ear tips
- Eyelids
- Belly
- Groin
- Around the lips
- Thinly covered areas of the legs
If your dog spends long periods lying in direct sunlight, these areas can become sunburned.
Which Dogs Are Most at Risk?
While any dog can suffer from sunburn, some are more susceptible than others.
Light-Coloured Dogs
Dogs with white or pale coats often have lighter skin that's more sensitive to UV exposure.
Examples include:
- West Highland White Terriers
- Dalmatians
- White Boxers
- Samoyeds
- Bull Terriers
Short-Haired Breeds
Dogs with very short coats have less natural protection.
These include:
- Greyhounds
- Whippets
- Staffordshire Bull Terriers
- Dobermans
- Vizslas
Hairless Breeds
Hairless dogs have little natural defence against the sun.
Examples include:
- Chinese Crested
- Xoloitzcuintli
- American Hairless Terrier
Dogs with Thin Fur
Senior dogs or dogs with certain medical conditions may develop thinner coats, leaving more skin exposed to UV rays.
Why Dogs Often Get Sunburned While Sleeping
Dogs don't always realise when they've become too hot.
If they're comfortable and relaxed, they may stay asleep in the same sunny spot for an hour or more, allowing prolonged UV exposure to the same areas of skin.
Unlike when they're active and moving between shade and sunshine, sleeping dogs often remain completely still, increasing their risk of sunburn.
Signs Your Dog May Have Sunburn
Sunburn isn't always immediately obvious.
Common symptoms include:
- Pink or red skin
- Warm skin
- Tenderness when touched
- Dry or flaky skin
- Peeling
- Excessive licking of affected areas
- Scratching
- Mild swelling
Severe sunburn can cause blistering or significant pain and should be assessed by a veterinarian.
Can Dogs Get Heatstroke While Sleeping?
Unfortunately, yes.
Dogs sleeping in direct sunlight may not only become sunburned but can also overheat if they're unable to move into the shade or cool themselves effectively.
Signs of overheating include:
- Heavy panting
- Excessive drooling
- Bright red gums
- Weakness
- Vomiting
- Disorientation
- Collapse
Heatstroke is a medical emergency and requires immediate veterinary attention.
How to Protect Your Dog Outdoors
Fortunately, preventing sunburn is relatively simple.
Always Provide Shade
If your dog is spending time outside, make sure they always have access to:
- Trees
- Garden umbrellas
- Gazebos
- Covered patios
- Pop-up pet shelters
Most dogs will naturally seek shade once they become warm but it's important the option is always available.
Avoid Peak UV Hours
The sun is strongest between 11am and 3pm during summer.
If possible:
- Walk your dog early in the morning.
- Exercise later in the evening.
- Encourage naps in shaded areas during the hottest part of the day.
Never Leave Dogs in Direct Sunlight for Long Periods
Even if the air temperature feels comfortable, surfaces such as patios, decking and artificial grass can become much hotter than expected.
Your dog may become uncomfortable or overheated surprisingly quickly.
Use Pet-Safe Sunscreen (When Appropriate)
For dogs with exposed skin, your veterinarian may recommend a pet-safe sunscreen.
Only use products specifically formulated for dogs, as many human sunscreens contain ingredients that can be harmful if licked.
Apply sunscreen to vulnerable areas such as:
- Nose
- Ear tips
- Belly
- Thin-haired skin
Always follow the manufacturer's instructions.
Choosing the Best Place for Outdoor Naps
If your dog enjoys sleeping outdoors, create a cool, comfortable resting area.
Look for somewhere that's:
- Shaded throughout the day
- Well ventilated
- Away from hot paving
- Quiet and relaxing
- Close to fresh drinking water
Many dogs appreciate having a familiar bed or mat outside so they have a comfortable place to settle.
Why a Comfortable Bed Still Matters Outdoors
Whether your dog is relaxing in the garden after a walk or enjoying a camping trip, having a supportive place to lie down helps them rest more comfortably.
A quality dog bed can:
- Keep your dog off hot patios and rough ground
- Cushion joints after exercise
- Encourage longer, more restful naps
- Provide a familiar place to settle
- Make outdoor relaxation even more enjoyable
If your dog regularly spends time outside, choose a bed that's easy to move and has a removable, washable cover for quick cleaning after muddy paws or sandy adventures.
What to Do If Your Dog Gets Sunburned
If you suspect your dog has mild sunburn:
- Move them into the shade immediately.
- Offer plenty of fresh water.
- Prevent further sun exposure while the skin heals.
- Avoid applying human creams or aloe vera products unless advised by your veterinarian.
- Monitor the affected area for worsening symptoms.
If the skin blisters, becomes very painful, or your dog appears unwell, contact your veterinarian promptly.
Enjoy the Sunshine Safely
There's nothing wrong with letting your dog enjoy a sunny afternoon outdoors, but moderation is key.
Providing shade, fresh water, and a cool, comfortable place to rest helps your dog enjoy the warmer months safely while reducing the risk of sunburn and overheating.

Frequently Asked Questions
Can dogs get sunburned through their fur?
Yes. While fur offers some protection, thin coats and lightly covered areas can still be exposed to harmful UV rays.
How long does dog sunburn last?
Mild sunburn often improves within a few days with proper care and avoiding further sun exposure. More severe cases may require veterinary treatment.
Should dogs sleep in direct sunlight?
It's best to encourage dogs to rest in shaded areas, particularly during the hottest part of the day.
Can black dogs get sunburned?
Yes. Although darker skin offers more natural protection, black-coated dogs can still develop sunburn on exposed areas such as the nose, ears and belly.
Is human sunscreen safe for dogs?
No. Many human sunscreens contain ingredients, such as zinc oxide and salicylates, that can be harmful if ingested. Always use a sunscreen specifically formulated for dogs and seek veterinary advice if you're unsure.
