So, do dogs really need to worry about sun exposure just because they have fur?
The answer is yes—just like us, dogs can suffer from the harmful effects of UV rays.
Let’s dive into what you need to know about keeping your dog safe when the sun is shining bright!
Are UV Rays Harmful to Dogs?
Just as with humans, prolonged exposure to the sun without protection can have negative effects on dogs, both in the short and long term.
While a dog’s coat and often darker skin do offer some level of protection against UV rays, they aren’t invincible. Sunburn and other skin issues are less common but definitely still possible.
Even brief sun exposure can lead to sunburn, resulting in skin inflammation that can be quite painful. Plus, repeated sun exposure and skin damage can eventually lead to skin cancers, just like in humans.
The areas most at risk are those with less fur, such as the tips of the ears and the nose.
Are Some Dogs More at Risk?
Certain factors can increase a dog’s vulnerability to sun exposure.
Very young, elderly, or frail dogs are more sensitive to heat, so they require extra care during sunny days. Additionally, dogs with pink skin, light fur, or pre-existing skin conditions are at a higher risk of sunburn. Hairless breeds are particularly exposed and need special attention.
It’s also worth noting that certain medications, like some diabetes medications, diuretics, and antibiotics, can make dogs more susceptible to sunburn. Always check with your vet if you have concerns about medications affecting your pup's skin.
Is Their Fur a Good Defense Against Harmful UV Rays?
While a dog’s fur can act as a barrier against the sun—reflecting some rays and providing a cushion—its effectiveness varies.
Dogs with short or light-coloured fur may still have areas of exposed skin that can be damaged by UV rays. So, while fur can help, it doesn’t mean your dog is entirely safe from sunburn.
What Precautions Should You Take Against UV Rays?
Now that you understand the risks, let’s talk about how to protect your dog when the sun is blazing.
One common mistake is underestimating UV exposure on cloudy days or when a breeze makes it feel cooler. UV rays are still very much present!
Here are some tips for sun safety:
- Timing is Everything: Try to avoid walks when the sun is at its peak (usually between 10 AM and 4 PM). Instead, opt for early morning or late evening strolls. Just remember to apply mosquito and tick prevention since those pesky critters are out during those times too!
- Find Shade: Keep your dog in the shade during the day, and make sure they always have access to fresh water. Hydration is key!
- Watch for Sunbathers: Some dogs love basking in the sun and might not realize they’re overheating. Keep an eye on them and limit outdoor time to avoid overheating.
- Sunscreen for Dogs: If you’re heading out, consider applying a dog-safe sunscreen—never use human sunscreen as it’s not suitable for their skin pH. Look for a sunscreen with an SPF of at least 15 and apply it before heading outside. Reapply every two hours or after swimming, focusing on vulnerable areas like the nose, ears, and groin. For hairless breeds, make sure to cover them completely!
Oops, Sunburn! What Should You Do?
This is how you recognise sunburns on dogs: the skin will be red, inflamed and feel hot to the touch. There may also be flaking.
If you notice any redness or burns on your dog’s skin, don’t wait for blisters or scabs to appear—those can lead to itching and infections if your dog scratches at them. Here’s what you can do to help:
- Cool It Down: Apply cold compresses to the affected areas to soothe the skin.
- Moisturize: Use a dog-friendly balm or natural aloe vera gel to help rehydrate the skin.
- Avoid Further Sun Exposure: Keep your dog indoors or in the shade until they heal.
If blisters appear or you don’t see any improvement, make a trip to the vet for professional help.
Remember, when the sun is out, UV rays aren’t the only risk for our pups.
Hot pavement, heatstroke, and dehydration are also concerns. As responsible pet parents, it’s up to us to ensure our dogs stay safe and comfortable in the heat, so that we can all enjoy the Summer fun!
