Fur gives pets a good deal of protection from the sun, but it is not complete coverage. Dogs and cats can sunburn, and repeated sun damage over years can contribute to skin cancers in some animals. Knowing which pets are most at risk, and where burns tend to happen, makes prevention straightforward. Late spring and early summer, when the sun is strong and pets are spending more time outdoors again, is a good time to think it through.
Who is most at risk
- Pets with white or very light-colored fur
- Pets with pink skin, especially on the nose, ears and belly
- Short-haired or thin-coated breeds
- Hairless breeds, which need special attention in the sun
- Dogs that have been closely shaved or clipped
- Pets that love to sunbathe, indoors or out
White cats deserve a special mention. Their ear tips and noses are particularly vulnerable to sun damage, and veterinarians have long linked repeated sun exposure in these areas to a form of skin cancer. Indoor cats can still get significant sun through windows, so their favorite sunny perch is worth thinking about.
Where burns happen
Burns usually show up on areas with little fur or thin, light skin: the bridge of the nose, the ear tips, the lips, the belly, the inner thighs and around the eyes. Dogs that sunbathe belly-up on a deck are prime candidates for a sunburned tummy. Signs can include reddened skin, tenderness, flaky skin and, in more serious cases, blistering. Over time, chronic sun damage may lead to thickened, crusty or scabbed areas that do not heal, which should always be checked by a veterinarian.
Reduce exposure
The simplest protection is limiting time in strong midday sun. Plan walks for early morning or evening, and make sure outdoor spaces have plenty of shade. Indoors, consider window films or shades on the sunniest windows, especially if you have a white cat who spends hours basking. For dogs who spend long periods outside, lightweight sun-protective shirts made for dogs can cover the back and belly.
A note on sunscreen
Do not use human sunscreen on pets without talking to your veterinarian. Some sunscreens contain ingredients, such as zinc oxide or salicylates, that can be harmful if a pet licks them off. Cats in particular are sensitive to many substances that are safe for people. Your vet can recommend whether a sunscreen is appropriate for your pet and, if so, a product formulated for animals.
When to see your veterinarian
Contact your veterinarian if your pet’s skin is red, painful or blistered after sun exposure, or if you notice sores, crusts or lumps that change or do not heal, especially on the ears, nose or belly. Early evaluation matters for skin changes. Your vet can also help you build a sun-safety plan for a pet with light skin or a thin coat, so summer stays comfortable.
