How do I get rid of my dog s rash
Rashes on Your Dogs Belly
Rashes on a dogs belly may look alarming and uncomfortable, but they are quite common. These dog belly rash bumps and redness you see can have a variety of causes, from a simple bacterial skin infection to a more serious underlying condition, such as Cushings disease.
If left untreated, your dogs belly rash could develop into an unpleasant skin infection that will require veterinary care and cause your dog discomfort.
Here is what you need to know about your dogs belly rash, including the causes, symptoms, and treatment options available.
What Causes Dog Belly Rashes?
Your dogs skin protects his body from the outside world, acting as a barrier between his internal organs and harmful organisms. We might think of skin as being tough and resistant, but it is actually very sensitive to changes in both your dogs body and the environment.
One of the ways the skin shows this sensitivity is through rashes.
There are several causes of rashes in dogs:
- Skin infections
- Inflammatory conditions
- Allergies (which many times are genetic)
- Parasites
- Genetic
- Hormonal imbalances and endocrine conditions
- Environmental causes (such as poison ivy or other plants)
Infections
Sometimes cuts can open the skin barrier to infections. Many of the causes of rashes in dogs are the result of bacterial, fungal, or yeast infections.
Bacterial skin infections are called pyoderma, which translates from Greek to pus and skin. Pyoderma typically causes lesions that look like pimples and can also cause crusty, dry, flaky skin. Hair loss and itchiness can also occur.
Your dog can get pyoderma as a result of trauma to the skin, like an abrasion or cut, excessive moisture, or as a secondary condition. Puppies are prone to puppy pyoderma in areas without a lot of hair, such as their underarms and groin. Hereditary factors can also play a role in skin infections for both puppies and adult dogs.
Fungal infections, such as yeast infections and ringworm, are also common. Yeast dermatitis is a skin condition caused by yeast infections. It is also known as Malassezia dermatitis and is caused by the fungus Malassezia pachydermatis. Symptoms of this condition include thickened skin; changes in skin pigmentation; a musty smell; itching; redness; scaling, crusty, flaky skin; and chronic ear infections.
Ringworm is characterized by circular lesions, which can appear red and scabbed. Hair loss is common, and while these rashes are usually not itchy, they can become inflamed, and the condition can be passed to people and other pets.
Allergies
Allergies can also cause rashes on your dogs belly. Environmental allergies, like contact dermatitis or reactions to something on the ground like fertilizer, cleaning products, poison ivy, or other irritants, flea allergy dermatitis, and food allergies, food sensitivities, and food intolerance can lead to itchy bumps and rashes. When your dog itches and scratches, he opens his skin up to infections, which can lead to a rash or complicate an existing rash.
Allergies can have a wide array of symptoms, from digestive upset to skin conditions such as itchiness, hair loss, redness, irritation, and chronic skin infections. Talk to your veterinarian if you suspect that your dog might have an allergy.
Pests and Parasites
Pests and parasites could also be the cause of your dogs rash. Fleas, mites, and ticks can cause irritation, exposing your dog to bacteria, yeast, and fungal infections. Demodex mites, walking dandruff, flea allergy dermatitis, and sarcoptic mange (caused by the Sarcoptes scabiei mite) can all cause rashes on your dogs skin, including her belly and groin area.
Genetic
Some dogs are more prone to rashes than others. Breeds that are predisposed to skin problems, such as Cocker Spaniels, German Shepherd Dogs, Labrador Retrievers, Bulldogs, Doberman Pinschers, and Standard Poodles, may be at an increased risk of developing rashes on their bellies and elsewhere.
Golden Retrievers, for instance, can get a rare condition called congenital ichthyosis, which causes scaling of the skin on the abdomen. Arctic breeds, for example the Samoyed, can develop zinc-responsive dermatosis, and Cocker Spaniels are prone to primary seborrhea (dandruff).
Hormonal Imbalances and Conditions (Endocrine Disorders)
Most concerning, however, is the possibility that your dogs belly rash could be a sign of an underlying condition, such as hypothyroidism or Cushings disease. These diseases cause hormonal imbalances in your dogs body, and some of the first obvious symptoms are often skin conditions, such as thinning or loss of coat and changes to the quality of the skin.
You can help your veterinarian catch these diseases early by observing your dog for any changes in coat quality, drinking and urination habits, as well as rashes, hair loss, and dry skin.
Symptoms of Belly Rash
Rashes on your dogs belly can present in a few ways. Perhaps the most common is pyoderma, which is characterized by pimple-like lesions; dry, scaly, crusty skin; hair loss; and itchiness.
Your dogs skin may also appear red and inflamed, weepy, or scabbed. Yeast infections can result in a yeasty smell, and fungal infections like ringworm often have a distinct, circular pattern to the lesions.

Diagnosing Your Dogs Belly Rash
The best way to determine the cause of your dogs belly rash is to make an appointment with your veterinarian, who will perform some diagnostic tests based on your dogs age, breed, overall health, and symptoms.
Veterinarians use skin samples, blood tests to detect underlying conditions, fungal cultures, antibiotic sensitivity tests, and in some cases, allergy testing to accurately diagnose skin conditions in dogs. Your veterinarian may refer you to a dermatologist for further testing and treatment.
Treating Belly Rashes
Once your veterinarian has diagnosed the cause of your dogs belly rash, she will discuss your treatment options.
Bacterial skin infections are typically treated with a course of antibiotics. Your veterinarian may want to perform an additional test to determine the best type of antibiotic to treat your dogs rash and avoid building up antibiotic resistance, and could prescribe you with medicated shampoos or scrubs to help manage the infection.
Yeast and other fungal infections are treated with antifungal medications and shampoos.
Allergies, depending on the cause, can be more difficult to treat, and may involve treating both the allergy and any secondary skin infections that developed. Your vet may recommend a dog skin soother balm to help ease the discomfort.
Conditions such as hypothyroidism and Cushings disease, like allergies, require treatment of the condition itself and the skin rash. Your dog may require additional blood tests and follow-up monitoring.
In some cases, your dogs belly rash could be the result of a resistant infection, such as methicillin-resistant Staphylococcus aureus (MRSA). It is very important to follow your veterinarians instructions about treating resistant infections, and you will need to be patient, as it may take time for the infection to heal.
Rashes on your dogs belly are not usually serious, but they do require medical attention. As a note of caution, some rashes can be transferred to people, like poison ivy or ringworm, so be careful to avoid touching the rash yourself, and make an appointment with your veterinarian today to get an accurate diagnosis for your dogs rash and to ensure that he stays happy, healthy, and active.
Dog belly rash? Heres how to soothe it
Dogs get belly rashes for a variety of reasons. Without pinpointing the exact cause, treatment can be ineffective and leave your pup still scratching and chewingso its essential to find the underlying cause. When your vet examines your dog, theyll be searching for signs of certain causes as the culprit for their belly rash.
Skin infections
Skin infections are one of the most common causes of belly rashes in dogs. These infections can be caused by multiple pathogens, like bacteria or yeast. A common type of bacterial skin infection is pyodermaTrusted SourceVCA HospitalsCommunity of veterinarians with up-to-date veterinary information.Go to source or impetigo. It can cause pimple-like, pus-filled lesions, and crusty, dry, flaky skin.
A pyoderma infection, on the other hand, is often caused by the staph species of bacteria, which usually occurs because of bacterial infiltration that stems from the skins surface. If the skin has been traumatized, such as through a cut, licking, or chewing, bacteria can multiply.
Fungal skin infections
Fungal infections, like ringworm and yeast infections, are also common. Ringworm is characterized by circular lesions that are usually hairless. These spots can appear red and scabby and generally dont cause itching, but that isnt always the case.
Keep in mind that ringworm is contagious and can be passed from your pup to you and other pets in your household.
Yeast dermatitis, caused by the fungus Malassezia pachydermatis, can appear as thickened, scaly, or flaky skin. Changes in skin pigmentation, a musty smell, itching, and redness are also common. Youll probably need antifungal medication from your vet to fully resolve this type of issue.
Excessive heat
Like people, dogs can also develop heat rashes. Often caused by the Staphylococcus bacteria, heat rashes can flare up in hot, humid weather. Heat rashes most commonly pop up in areas where the skin rubs, like under the tail, the neck, and the ears. Typically, a heat rash will start as mild skin irritation (or hot spot), which leads to excessive scratching. With time, it can progress to pimples or scabs that have a foul odor.
To soothe the heat rash, soak a washcloth in cool or room temperature water and apply it to the affected area as it may provide temporary relief from any inflammation.
Dont apply ice packs directly to your pets skin. Instead, wrap packs in a dry towel or washcloth to create a cold compress.
Allergies
A belly rash is a common sign of allergies in dogs. Pets who are allergic to certain fabrics, shampoos, cleaners, fertilizers, and other chemicals can develop itchy, red skin and pimple-like bumps on their stomach.
Seasonal allergies can also cause belly rashes on your pup. If your dog has an allergic reaction to grass, pollen, weeds, or trees, they may develop a belly rash after playing in the yard.
Parasites
Parasites, like fleas, ticks, and mites, can cause your pup to break out in a belly rash. Bug bites and stings from ants, bees, and wasps can also lead to irritated skin, and mites in particular can lead to painful conditions like sarcoptic mange. In the cases of bites or bug-related irritation, youll likely notice hair loss, hot spots, scabs, or a rash on your dogs lower back, hind legs, and tail base.
Keep in mind that fleas like to hang out on your dogs hind end, though, so they may not cause an abdominal rash.
Rashes on Dogs
A rash (pyoderma) is usually a temporary outbreak of scaly, patchy, and sometimes swollen or bumpy skin that is often red and may be itchy.
A rash can occur on any part of your dogs body, but it pops up most often on the belly. A rash by itself is usually minor and often goes away on its own, but it can be a sign of a more serious situation. The cause of rashes on a dog can range from parasites to diabetes.

Diagnosing Rashes on Dogs
Your vet will give your dog a physical exam and ask questions about your dogs diet, current health issues, home environment, and other factors. To diagnose a rash, your veterinarian will perform a number of tests, depending on the suspected cause, including:
Allergy tests if an allergen is suspected. This may include a food elimination diet or intradermal allergy testing.
Skin scraping to look for mites, bacteria, fungus, or other potential causes.
Skin biopsy, where a piece of skin is examined at a pathology laboratory (done in cases of recurring infection or rash).
Blood profile to check for diseases such as thyroid issues (hypothyroidism) or Cushings disease
Treatment for Rashes on Dogs
To eliminate the rash and make sure it doesnt come back, your vet will need to find and treat any underlying medical condition thats causing it.
They may also recommend several treatments for the rash and related symptoms. These may include:
Grooming (such as brushing or cutting away hair)
Oatmeal baths
Medicated dog shampoo (containing antifungal or antibacterial ingredients)
Anti-itch and anti-inflammatory medications
Elizabethan collar or e-collar to prevent a dog from irritating hot spots by licking or biting
Epsom salt foot soaks if your dogs paws are inflamed. Follow your veterinarians instructions, as these can dry out the skin if used inappropriately. Do not allow your dog to drink the solution, which has high sodium levels.
