Yeast Infections in Dogs: How to Treat Paws, Ear, Belly, and Skin | PetMD

Yeasts are spore-producing fungi that are always present on a dog’s skin, usually in low numbers, as part of the normal flora. A yeast infection occurs when there is an excessive amount of yeast in a certain area.

Yeast infections in dogs are fairly common and can occur anywhere on the skin, including the ears.

Yeast infections are usually caused by another problem. Anything that lowers the skin’s normal defenses can make yeast infections more likely.

Dog breeds that are more prone to yeast dermatitis include:

  • shih tzus
  • western highland white terrier
  • American cocker spaniel
  • basset hound
  • setters English
  • boxers
  • poodles
  • dachshunds
  • australian silky terriers

what causes yeast infections in dogs?

Yeast infections in dogs are usually secondary problems. This means that some other problem is weakening the skin’s defense mechanisms to allow the yeast to grow in larger numbers than normal.

It is very common to see thrush in a dog’s ears or on his skin if he has food or environmental allergies. Other underlying issues that can cause thrush in dogs include hormonal issues or other diseases that suppress the immune system.

There are no studies to confirm that any of the following cause fungal skin infections in a dog:

  • antibiotics

    brewer’s yeast

    oatmeal shampoos

    carbohydrates or sugar in food

    what are the symptoms of candidiasis in dogs?

    fungal infections can cause redness, irritation, or itching of the skin or ears, and there is often a sweet or musty odor.

    chronic yeast infections can cause the skin to become thickened and discolored (gray, brown, or black).

    These are the most common areas of thrush in dogs and some signs to watch for.


    Yeast infections can occur anywhere on a dog’s skin, including the belly. They are often seen in areas that are moist, such as in skin folds, especially in “wrinkled” breeds of dogs.

    Affected skin may be red, irritated, itchy, greasy, or scaly, and there may be hair loss.

    If the infection is chronic, the skin may thicken and darken. yeast infections in a dog’s mouth or face can cause extreme itching or rubbing of the face.


    A dog with thrush on its paws may have red, sore, itchy paws.

    The bottom of the feet, between the pads, is most often affected, but the yeast can appear anywhere on the feet. sometimes a brown discharge can be seen on the nail beds.

    Dogs with thrush on their paws tend to lick their paws more than usual. there may also be hair loss.


    Dog ear yeast infections are fairly common, and the ears often smell sweet or musty.

    You will usually see redness, which may extend to the ear flap, and the discharge is usually brown. the ear may appear greasy and the hair may be matted.

    Yeast infections in a dog’s ears can be very itchy, causing dogs to scratch their ears or rub their heads excessively.

    what is the difference between ear mites and fungal infections in dogs?

    Fungal infections in a dog’s ears typically cause redness, brown discharge, head shaking or rubbing, a bad odor, and itching.

    Ear mite infections are very itchy and can cause many of the same symptoms. discharge from the ear is usually dark and waxy or crusty. Ear mites are barely visible to the naked eye and highly contagious to other animals.

    Your veterinarian can easily determine if a dog’s ear problem is caused by yeast or mites by taking a swab from the ear and looking at it under a microscope.

    what is the best treatment for canine candidiasis?

    The best treatment for a yeast infection in a dog depends on the location of the yeast infection.


    Your veterinarian can perform a cytology (taking a sample of the discharge and staining it for viewing under a microscope) to diagnose a dog’s ear yeast infection.

    Prescription treatment may include antifungal drops or ointments, an ear cleaner, and, in severe or difficult-to-treat cases, an oral antifungal medication.

    skin and legs

    cytology is also used to diagnose skin fungus.

    Treatments for fungal skin infections may include topical antifungal creams, wipes, sprays, and shampoos.

    Topical ingredients that are effective in treating yeast include chlorhexidine, miconazole, and ketoconazole.

    In difficult-to-treat or severe cases, oral antifungal medications are used. Oral antifungal medications used in dogs include fluconazole, terbinafine, ketoconazole, and itraconazole. these medications should be used only under the direction of a veterinarian.

    Human medications should not be used unless directed by a veterinarian.

    Are there home remedies for candidiasis in dogs?

    People often talk about home remedies for yeast infections in dogs, but most have not been proven to be effective.

    There are no studies to confirm that feeding any of the following is beneficial for treating a dog’s skin yeast infection:
