If you’ve noticed small black or dark spots appearing on your Maltese dog’s skin, especially after they’ve been enjoying time in the sun, you’re not alone. This is a relatively common observation among Maltese owners, and while it can be a little surprising at first, in most cases, it’s nothing to be overly concerned about.
Let’s take a closer look at why these spots develop, when to worry, and how to protect your Maltese from potential sun-related skin issues.
Understanding the Maltese Coat and Skin
The Maltese breed is known for its stunning white coat, which gives it a clean and elegant appearance. But underneath all that silky fur is very sensitive, light-colored skin that’s more exposed to sunlight than many owners realize—especially if the coat is trimmed short during warmer months.
Because their skin lacks heavy pigmentation, Maltese dogs can be more prone to sun sensitivity. Just like humans, their skin responds to UV rays, and one of those responses can be the appearance of darker spots or patches of pigmentation.
What Are These Black Spots?
In many cases, the black or dark spots you’re seeing are simply areas where melanin—the pigment responsible for skin color—has increased. This is called hyperpigmentation, and it can be triggered by a number of things, including:
- Sun exposure
- Aging
- Hormonal changes
- Skin irritation or friction
- Previous infections or allergic reactions
If the spots appear gradually, are flat, and your dog shows no signs of discomfort, it’s likely harmless pigmentation.
Why Sun Exposure Triggers Pigmentation
Just like in humans, exposure to sunlight can stimulate the production of melanin in a dog’s skin. This is the body’s natural way of protecting itself from UV radiation. For Maltese dogs, whose skin is often very fair, this reaction can be more noticeable.
This is especially common in areas where the coat is thinner, such as the belly, inner legs, or armpits. After repeated exposure, you may start noticing these dark patches appearing and becoming more visible over time.
When to Worry About Skin Spots
While most black spots from sun exposure are benign, there are a few warning signs that may require veterinary attention:
- The spot is raised or growing quickly
- It’s accompanied by hair loss or crusty skin
- Your dog is scratching or licking the area frequently
- The skin feels warm, swollen, or irritated
- New spots are appearing rapidly across the body
These symptoms could indicate a skin infection, allergic reaction, or in rare cases, skin cancer. Always consult your vet if you’re unsure or notice any of the above symptoms.
How to Protect Your Maltese from the Sun
Since Maltese dogs have such delicate skin, sun protection should be part of their regular care—especially during the summer months. Here are some simple steps to help reduce the risk of sun-related skin changes:
Limit Midday Sun Exposure
Try to avoid taking your Maltese out during peak UV hours (10 AM to 4 PM), especially on hot, cloudless days.
Use Pet-Safe Sunscreen
There are sunscreens made specifically for dogs that can be applied to sensitive areas like the belly, nose, or ears. Never use human sunscreen, as it can contain ingredients toxic to pets.
We can recommend this Sunscreen spray from Amazon.
Leave the Coat a Bit Longer
If you’re planning to trim your Maltese during the summer, avoid shaving them too short. Their coat acts as a natural barrier against sunburn.
Provide Shade and Fresh Water
If your dog spends time outside, make sure they always have access to shaded areas and stay hydrated.
Protective Clothing
Lightweight UV-protective shirts for dogs are now widely available and can be a stylish and effective way to protect their skin.
Final Thoughts
Noticing black spots on your Maltese’s skin can be surprising, but in most cases, it’s just a natural reaction to sun exposure and nothing to panic about. Still, it’s always a good idea to monitor any changes in your dog’s skin and behavior. When in doubt, a quick visit to the vet can bring peace of mind.
By taking simple precautions and staying observant, you can help keep your Maltese happy, healthy, and glowing—without any unexpected surprises from the sun.
