Why Is My Dog Getting Spots On Her Belly?

Seeing spots on your dog’s belly can often be scary and alarming, but it’s a lot more common than you think. Belly spots and rashes can form for a variety of different reasons, from simple bacterial infections to more serious underlying health conditions. 

However, if these spots are left untreated, there’s every chance that your dog could develop a range of unpleasant skin infections that cause a considerable amount of discomfort. Therefore, diagnosis and suitable medical treatment is incredibly essential. 

Why Is My Dog Getting Spots On Her Belly

In this guide, we’ll take a closer look at some of the common factors that can cause spots and rashes on a dog’s belly. We’ll also look at the most effective way you can treat the issue, as well as answers to a few of the frequently asked questions. 

Causes Of Spots And Rashes

As is the case with human beings, healthy skin is essential for dogs as it protects their bodies from the outside world – providing an important barrier between harmful organisms and their internal organs. 

While you might think a dog’s skin would be tough and resistant, it’s actually incredibly sensitive to changes in both the body and the environment. With this in mind, listed below are five of the most common causes of spots and rashes in dogs. 

Skin Infections

If your pooch suffers a cut to their skin, this can often open the skin barrier to nasty infections. In fact, the vast majority of spots and rashes in dogs are the result of bacterial, yeast, or fungal infections.

Bacterial skin infections are commonly known as “pyoderma”, and these infections can often cause lesions that look very similar to pimples. Pyoderma can also result in dry flaky skin, as well as itchiness and hair loss. 

The most common cause of pyoderma is trauma to the skin. In other words, a notable cut or abrasion. However, the issue can also form as a result of excessive moisture or as a secondary condition from something else. 

Yeast infections and fungal infections such as yeast dermatitis and ringworm are also possible. The former can cause symptoms like thickened skin, redness, and scaling, while the latter is characterized by red (and often scabbed) circular lesions.


Some dogs are more susceptible to spots and rashes than others. For example, breeds such as the Labrador Retriever, Poodle, German Shepherd and Cocker Spaniel are all predisposed to skin problems, making them far more likely to develop a rash on their belly. 

Another prominent example is the Golden Retriever which can sometimes develop a rare condition known as “congenital ichthyosis”. One of the main symptoms of this condition is a scaling of the skin on the abdomen. 


Allergies can also lead to your dog developing a rash or some spots on their belly. Whether this is a reaction to something they come into contact with on the ground such as fertilizer, or it’s a reaction to something else like a food intolerance, allergies can often result in itchy bumps and a rash. 

Furthermore, most allergies typically feature a wide range of symptoms, including redness, irritation, hair loss, poor digestion, and much more. So, if you suspect that your pooch might have an allergy, it’s a good idea to talk to your veterinarian. 


Pests and parasites are another common cause of spots and rashes on a dog’s belly. For example, fleas, ticks, and mites can all cause a considerable amount of irritation for dogs, exposing their skin to a host of bacteria, yeast, and fungal infections. 

What’s more, flea allergy dermatitis, demodex mites, sarcoptic mange, and walking dandruff can all contribute to rashes on your dog’s skin – especially in the areas of the belly and groin. 

Hormonal Imbalances

Perhaps the most worrying cause of your dog’s belly spots is the possibility of it being a sign of an underlying health condition such as Cushing’s disease or hypothyroidism. Both of these diseases typically cause a series of hormonal imbalances in your dog’s body, with the first symptoms often linked to their skin. 

With this in mind, make sure you keep a close eye on any changes in your dog’s coat quality, as well as looking out for any dry skin, rashes, and hair loss. This kind of cautious approach will help you to catch any harmful diseases early on before they get worse. 

Diagnosing Belly Spots

Why Is My Dog Getting Spots On Her Belly

The most effective way to find out the root cause of your dog’s belly spots is to see your veterinarian. They’ll be able to perform a range of diagnostic tests on your dog’s age, overall health, breed, and symptoms. 

Furthermore, veterinarians can use blood tests and skin samples to test for underlying conditions, as well as antibiotic sensitivity tests, fungal cultures, and allergy testing to detect various skin conditions in dogs. 

If your veterinarian deems it necessary, they may refer you to a dermatologist who can carry out further tests and treatment. 


Once the cause of your dog’s belly spots has been determined, you can then begin suitable treatment. Bacterial skin infections are usually treated with a course of antibiotics, while yeast and other fungal infections require antifungal medications and shampoos. 

Unfortunately, allergies are often more difficult to treat depending on the cause. For example, you might have to treat any secondary skin infections as well as the allergy. Lots of vets recommend a soother balm to help ease your dog’s discomfort. 

Furthermore, some of the more serious conditions like Cushing’s disease and hypothyroidism require treatment of not only the condition, but also any spots or rashes on the skin. More often than not, your pooch will need additional blood tests and regular follow-up checks.
