What are the possible causes and treatments for brown spots on dogs skin? You may have noticed some brown spots on your light-coloured fur. They can vary in size and shape and may or may not cause the dog discomfort. But what are these spots? Is it something to be concerned about?
Let’s have a look!
What Are Brown Spots on Dogs Skin?
They are area of increased pigmentation or melanin in the skin cells.
Melanin is the substance that gives colour to the skin and hair, and various factors, like genetics, sun exposure, hormones system, inflammation, and infection.
Some brown spots are normal, while others may mean they have an health issue that needs to be addressed.
Here are some of the common causes of brown spots on dogs skin:
Natural Breed Dapples
Some dog breeds have natural brown spots on their skin as part of their coat pattern. These are similar to birthmarks in humans, usually from birth or developing during puppyhood.
You shouldn’t worry about it as long as they do not change in size, shape, or colour over time.
Hyperpigmentation is when the skin produces too much melanin in response to chronic irritation or inflammation.
It usually results in skin darkening and may also become thicker and rougher in texture.
It can be caused by factors like;
They can be allergic to food, environment, or flea bites.
Bacterial, fungal, or parasitic infections can cause skin irritation.
Some hormonal disorders can affect dogs’ skin and hair growth.
Changing your dog’s food, administering allergy medications, using topical treatments, and utilizing antibacterial shampoos are all ways to address hyperpigmentation.
To reduce the inflammation and suppress the immune system, your veterinarian may occasionally prescribe oral steroids or other medications.
As dogs age, their skin may develop brown spots as a result of sun exposure or aging. These patches are usually not harmful. They appear on sun-exposed areas such as the nose, ears, or back.
Brown spots on dogs’ skin may be a symptom of skin cancer in rare circumstances. Skin cancer can affect any breed or age of dog, although it is more common in dogs with light-colored fur or skin, as well as dogs who spend a lot of time outside.
When to See a Vet for Brown Spots on Dogs Skin
You should see a vet for brown spots on your dog’s skin if:
- The spots are new or have changed in size, shape, colour, or texture.
- The spots are causing your dog discomfort, such as itching, pain, or bleeding.
- Other symptoms, such as hair loss, weight loss, lethargy, or loss of appetite accompany the spots
- The spots are suspicious for cancer, such as irregular borders, asymmetry, multiple colours, or larger than 6 mm in diameter.
Your vet will examine your pet and may also perform some tests, such as blood tests, urine tests, skin scrapings, fungal cultures, or biopsies.
They will diagnose the cause of the brown spots and prescribe the appropriate treatment based on the result.
Brown spots on the skin of dogs are not usually cause for concern. They could be natural marks in your dog’s coat pattern, or they could be caused by sun exposure or aging.
As a result, it is good to check your dog’s skin frequently and to consult a vet if you see any changes or signs. You can protect your pet’s health by doing so.
