Belly Yeast Infection On Your Dog: Our Vet Shares What to Do
Dogs can develop yeast skin infections anywhere on their body. Some of the most common places would include inside ears, inside skin folds and on the belly, armpits and groin. Certain breeds will be more prone to yeast infections, including Bassett Hounds, Pugs and Westies.
For most dogs, yeast infections on bellies are caused by underlying issues such as hormonal disorders, parasites or allergic skin disease. While there will always be some yeast on the skin, an overgrowth causes discomfort, skin inflammation and itching. In this article, we will review what yeast infections look like on a dogs belly and discuss treatment options.
What does a yeast infection on the belly look like?
It is not always easy to differentiate between different types of infection e.g. bacterial vs yeast infections. Often the signs are the same. To know the difference, we can swab the lesion or take an impression smear, looking at the microorganisms under the microscope.

In practice, this is not always done as it is costly and swabs take time to culture. Most canine skin infections are treated empirically. This means we provide medicine like medicated washes and antibiotics, which will usually clear up most skin infections on the belly.
Some of the more classic signs of a yeast infection include a musty smell, crusting, pink, red or dark (hyperpigmented) skin, mild itching and lichenification (thickening of the skin). With more chronic and advanced infections, the itching will become more severe.
Why does my dog keep getting yeast infections?
If your dog is prone to yeast infections, there will generally be an underlying reason. Rather than simply treating the infections time and time again, we should start asking what we can do to prevent them occurring.
In older dogs, it is a good idea to run some blood tests to check for hormonal disorders, like hypothyroidism. This is especially true when dogs have other symptoms such as lethargy, a change in weight or a change in thirst.
Allergies should always be considered. They tend to present between the ages of 6 months and 5 years and cause itchiness, pink skin and secondary bacterial and yeast infections. When the belly is affected, it is wise to consider environmental allergens such as pollens, grasses and trees.
How can I treat this yeast infection?
Mild and localized belly skin infections can be treated with topical solutions such as Chlorhexidine washes. In some cases, we can use topical anti fungals like Miconazole. Much less commonly, when the infection is longstanding or widespread, oral antifungals will be considered. These can cause a range of side effects so are not used lightly.
When using medicated washes like Chlorhexidine (Hibiscrub), we need to use them in a specific manner. Generally, we dilute them 1:10 in water and apply with cotton wool. We then leave it on for 5-10 minutes, before rinsing with water and pat dry.

When dogs are scratching or licking at their belly, we want to stop this. This can mean the use of a buster collar and perhaps a loose cotton t-shirt. Excessive rubbing and licking can lead to worse itching and more infections being introduced.
With any skin infection, a trip to the vet for a diagnosis and treatment plan is important.

Yeast Infections in Dogs
What Are Yeast Infections in Dogs?
Does your dog frantically itch their skin? Have you noticed a bad smell or greasy fur when you pet them?
If so, they may have a yeast infection.
Yeast are fungal organisms that normally live on a dogs skin without causing problems. However, when a dogs immune system weakens or an underlying health condition, such as hypothyroidism, is present, yeast can overgrow and cause an infection.
The yeast that commonly causes skin infections in dogs is Malassezia, which grows on warm, moist areas of the skin. Yeast infections cause extreme itchiness and changes to the skin, such as thickening and discoloration over time.
Yeast infections in dogs are common among pups of all ages.
While yeast infections in dogs are not considered medical emergencies, they should be treated by a veterinarian immediately to prevent symptoms from worsening. If left untreated, yeast infections can cause extreme discomfort, which can lead to a decreased appetite and lethargy, necessitating prompt veterinary care.
Because yeast infections typically develop secondary to an underlying illness or suppressed immune system, they are not contagious among dogs or to pet parents.
Types of Yeast Infections in Dogs
Yeast infections can affect various areas of the skin, including the ears, skin folds, paws, armpits, vulva, and groin.
EarsYeast infections of the earalso referred to as yeast otitiscause a thick, brown discharge and strong odor in the ear canal. Affected dogs repeatedly scratch their ears to try to relieve the discomfort. They may also shake their heads and develop a head tilt. Ear infections are commonly related to food allergies.
SkinYeast dermatitis refers to a yeast infection anywhere on the skin. Affected dogs have a musty odor, greasy coat, flaky or thickened skin, and hair loss. They tend to lick the affected areas of the body, which leads to brown discoloration of the skin over time.
Dermatitis, which is often due to allergies or a suppressed immune system, can affecta dogs skin folds, armpits, vulva, and groin.
PawsYeast infections that affect the paws are generally related to environmental allergies, such as allergies to grass or pollen. Dogs constantly chew or lick their itchy paws, which leads to brown discoloration between the paw pads. Over time, open sores can develop on the paws.
Symptoms of Yeast Infections in Dogs
Signs of yeast infections in dogs can vary depending on what area of the body is affected.
Symptoms of yeast otitis may include:
Symptoms of yeast dermatitis may include:
Itchy skin
Small, red bumps on the skin
Brown discoloration of the skin
Frequent licking or chewing of the affected area
Greasy hair coat
Thickened skin
Strong odor
Symptoms of a yeast infection affecting the paws may include:
Licking and chewing the paws
Brown discoloration of the skin and fur
Red, moist areas between the paw pads
Causes of Yeast Infections in Dogs
Yeast is opportunistic, which means that although it is naturally present on the skin, it can cause an infection when conditions are favorable.
Yeast infections in dogs can develop if a pup has a weak immune system or an underlying health condition. Underlying environmental or food allergies can predispose dogs to developing yeast infections.
Skin parasites, including fleas and mites, can cause dogs to repeatedly itch their skin, which disrupts the normal skin barrier, making an infection more likely.
Some breedssuch as Pit Bulls, Boxers, and Cocker Spanielsare more frequently affected by yeast infections.
How Veterinarians Diagnose Yeast Infections in Dogs
A vet may use several tests to diagnose a yeast infections in dogs.
First, they will gather a through medical history, including when the symptoms started, if your pet is taking any medications, and if they have previously been diagnosed with any health conditions.
Next, your veterinarian will perform a full physical exam to check your dogs overall health. They may also perform blood work to check for any abnormalities.
Additional tests will depend on what your veterinarian finds during the initial exam, but may include the following:
Tape impressionDuring this test, your vet presses a piece of clear tape to the affected area of skin to collect a sample. Its then stained and examined under a microscope to identify yeast.
CytologyA cotton swab is used to collect a sample from the affected area, and it is then rubbed gently onto a microscope slide. The sample is then stained and examined under a microscope to look for yeast.
CultureA sterile cotton swab is used to collect a sample from the affected area. It is then sent to a lab to identify the type of organism present.
Skin biopsyFor chronic infections or those that are unresponsive to treatment, a small sample of skin can be taken and sent to a lab for a more accurate diagnosis.
Treatment of Yeast Infections in Dogs
Treatment for yeast infections in dogs will depend on the location and severity of the infection. Yeast dermatitis is often treated with antifungal medications and prescription shampoos.
If the infection affects only one area, a topical medication may be all that is needed. For more widespread infections, oral medications and frequent bathing can help resolve the issue.
Yeast otitis is typically treated with topical antifungal medications and steroids to reduce inflammation. Your veterinarian may recommend that you use a medicated ear wash prior to instilling ear medications.
Paw yeast infections may benefit from medicated antifungal wipes and oral medications, including antifungals and steroids.
Recovery and Management of Yeast Infections in Dogs
Because yeast infections in dogs often develop secondary to another health condition, they will not resolve without veterinary treatment.
Determining the underlying cause of the yeast infection and treating it accordingly improves treatment success. For example, if your dog has an underlying food allergy, an accurate diagnosis and treatment can help their skin improve.
It can take a few weeks to a few months for a yeast infection to fully resolve, depending on the severity. Most dogs start to feel relief from their symptoms in a week or two, but it can take several additional weeks for a pet parent to notice significant improvement to their skin and coat.
Prevention of Yeast Infections in Dogs
Ensuring your dog receives regular preventive care and vaccinations keeps them healthy and less likely to develop infections.
Additionally, health conditions that can lead to yeast infections in dogs can be caught and managed early during routine wellness visits.
Yeast Infections in Dogs FAQs
What food causes yeast infections in dogs?
Most of the food ingredients that cause allergies in dogs are proteins. Chicken is the most common food allergen related to yeast infections.
What happens if dog yeast infections go untreated?
If a dogs yeast infection is left untreated, it will progressively worsen and lead to extreme discomfort. Over time, the discomfort can cause the dog to become very sick.
What should I feed my dog when they have a yeast infection?
Unless the yeast infection is due to an underlying food allergy, its generally fine to continue your dogs usual diet. However, it is best to follow your veterinarians recommendations when deciding what to feed your dog.

Identifying and Treating Fungal Infections in Dogs
By Reyna Gobel
Bacteria and viruses are what typically spring to mind hen pet parents think infection, but fungi can also be to blame. While not as common as bacterial or viral infections, fungal infections can be just as serious. Dogs can contract fungal infections from other animals, from the environment, or as a result of the overgrowth of fungi that are naturally present on their own bodies. Every pet is potentially at risk for contracting a fungal infection, and an accurate diagnosis is necessary before appropriate treatment can begin. Read on to learn more about fungal infections in dogs.
Fungal Skin Infections
When your dog starts scratching himself more than is normal, it can be hard to tell whether its because of an allergy, flea bites, infection, or something else. Excessive itching can be quite worrisome, especially if your dog develops bald spots or damages his own skin as a result.
One telltale sign of fleas is the presence of flea dirt (small black clumps of flea feces) on your dogs skin and fur. If you see flea dirt or actual fleas, treat him right away. But if fleas or ticks arent to blame, dont self-diagnose or rely on Dr. Google, warns Dr. John DaJong, a veterinarian at Newton Animal Hospital in Massachusetts. After performing a complete physical exam, your veterinarian can conduct specific tests to help diagnose the problem and identify whether a fungal infection is to blame.
Lets look at two common types of fungal infections that affect the skin of dogs and how to treat them.
Ringworm
Ringworm is a common fungal infection in pets. It can affect a dogs skin, fur, and also the nails. Common symptoms include hair loss, itching, flaky or crusty skin, and misshapen or brittle nails. While you should treat any infection as soon as possible, time is of the essence with ringworm because it can easily spread to other household animals and humans, says Dr. Andrew Rosenberg, a veterinarian at Riverdale Veterinary Dermatology clinic in Riverdale, New Jersey.
To diagnose ringworm, your veterinarian will perform a fungal culture of hair or skin cells or a microscopic examination of a hair sample. Depending on the severity of the infection, ringworm may be treated with medicated baths and dips and/or oral antifungal medications. Vacuuming and disinfecting the house will also help lessen the chances that ringworm will spread between pets and people.
Yeast Infection
Overgrowth of yeast on a dogs body can lead to irritating yeast infections, commonly affecting the skin, paws, and ears. These infections can be extremely uncomfortable for dogs, says Rosenberg. Theyre generally secondary to allergies or other conditions that disrupt the skins ability to control the yeast that normally live there.
If I suspect a dog might have a yeast infection, I take an impression smear of the area that might be infected and look at it under a microscope, Rosenberg says. When the slide is stained, the yeast look like little purple peanuts.
Treatment normally involves an antiseptic or antifungal drug applied to the skin. Oral medications may be necessary in severe cases. Unlike ringworm, yeast infections arent contagious to other pets or people. To prevent yeast infections from recurring, its important to treat any underlying conditions as recommended by your veterinarian.
If your pet is constantly itching and scratching, schedule an appointment with your veterinarian. Unfortunately, not all conditions can be solved with one visit. Sometimes it could take several visits to pinpoint the cause of your dogs itching or require a visit to a veterinary dermatologist, Rosenberg says.
Systemic Fungal Infections
Fungal infections on the surface of the body are bad enough, but those that invade deeper structures can have even more serious consequences. Lets look at several common types of systemic fungal infections in dogs and how to treat them.
Blastomycosis
Blastomycosis is most commonly diagnosed in dogs that have spent time in Mississippi, Ohio, Missouri, Tennessee, the St. Lawrence River valley, the mid-Atlantic, and around the Great Lakes because the types of soil that are typically found in these areas support the growth of the fungus. Dogs that spend time sniffing around in the dirt are at risk for inhaling fungal spores, which can lead to a lung infection, says Dr. Jennifer Coates, veterinarian and author of Dictionary of Veterinary Terms, Vet-Speak Deciphered for the Non-Veterinarian. From there, the organism can travel almost anywhere in the body. According to Coates, common symptoms include poor appetite, weight loss, coughing, difficulty breathing, limping, eye problems, skin lesions (particularly around the toenails), enlarged lymph nodes, and fever. If the disease is caught early enough, treatment with an oral anti-fungal medication can be curative.
Cryptococcosis
While cats are more commonly infected with the fungus Cryptococcus, Coates says dogs tend to develop a more severe form of the disease. The fungus is present in soils world-wide but may be especially prevalent in areas where pigeons and other birds congregate. As is the case with blastomycosis, dogs typically inhale the Cryptococcus fungus, leading to a lung infection. It can then spread almost anywhere in the body, which can cause symptoms ranging from lethargy, coughing, nasal discharge, eye problems, skin lesions, and even seizures and other neurologic abnormalities. Coates warns that treating cryptococosis can be difficult. Oral antifungal medications may need to be given for a year or more and some dogs will still succumb to the disease.
Coccidioidomycosis
Dogs can get coccidioidomycosis (also known as Valley Fever) from inhaling dust or dirt that contains coccidioides fungal spores,says Dr. Carol Hillhouse, a veterinarian in Panhandle, Texas. It tends to grow in desert areas with little rain and sandy soil, such as California, Nevada, Arizona, New Mexico, and Texas, she says. Strong winds, earthquakes, construction areas, and even crop harvesting can stir up the spores into the air.
Once the spores are inhaled, the fungus may simply cause a chronic cough, Hillhouse says. In other cases, especially if immunosuppressed, the dog may develop pneumonia or the fungus can spread to other areas in the body, such as bone or the eyes, she says. It can be difficult to diagnose, and usually requires radiographs, blood, and cell testing. Valley fever requires long-term treatment with oral antifungal medications, but the prognosis is pretty good if caught early, she says.
Histoplasmosis
Another soil-borne fungus, Histoplasma, prefers the temperate climates of Ohio, Mississippi, and Missouri River Valleys, Hillhouse says. This fungus grows best in nitrogen-rich soil, such as bird and bat excrement, and is usually acquired by inhalation of the organism from the environment.Infected dogs can show weight loss, fever, cough, eye inflammation, vomiting, and diarrhea, she says. Often, a combination of blood and urine tests, as well as radiographs, are used to make the diagnosis. Sometimes biopsies are required as well. Treatment involves long-term fungal medication, but prevention is best by restricting access to soil that is contaminated with bird or bat droppings.
Aspergillosis
Infections with Aspergillusfungus are usually limited to a dogs nasal passages. Aspergillosis can affect dogs residing in almost any part of the country since the fungus is present in most soils. Treatment typically involves anesthetizing the pet and infusing his nasal passages with a liquid anti-fungal medication. Most dogs will recover if treated appropriately, although a second treatment may be necessary in some cases.
Preventing Fungal Infections in Dogs
Fungal infections in dogs range from localized annoyances to potentially fatal systemic diseases. Prevention is not always possible, but common sense measures can help. If you live in an area where a certain type of fungal infection is endemic, avoid high risk environments. Pets with ringworm should be isolated to limit the spread of the disease to people or other animals. Finally, appropriately manage any underlying health problems that increase your dogs risk for developing a fungal infection.
