Yeast Infection in Dogs?

Yeast are spore-producing fungi that are always present on a dogs skin, usually in low numbers, as part of the normal flora. A yeast infection happens when theres an excessive amount of yeast in a certain area.

This means that there is some other issue that is weakening the skins defense mechanisms to allow the yeast to grow in higher numbers than normal. Other underlying issues that may cause yeast infections in dogs include hormonal problems or other diseases that suppress the immune system.

There are no studies to confirm that any of the following cause yeast infections on a dogs skin: Yeast infections can cause red, irritated, or itchy 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).

Yeast infections can occur anywhere on a dogs skin, including the belly. They are often seen in areas that are moist, such as in skin folds, especially in wrinkly dog breeds. The affected skin may be red, irritated, itchy, greasy, or flaky, and there may be hair loss.

Yeast infections in a dogs ears generally cause redness, a brown discharge, head shaking or rubbing, odor, and itching. Ear mite infections are extremely itchy and can cause many of the same symptoms. Ear mites are barely visible to the naked eye and highly contagious to other animals.

Your veterinarian may perform cytology (taking a swab of the discharge and staining it to look at it under the microscope) to diagnose a yeast infection in a dogs ears. Treatments for yeast infections on the skin can include topical antifungal creams, wipes, sprays, and shampoos. Topical ingredients that are effective in treating yeast include chlorhexidine, miconazole, and ketoconazole .

Oral antifungal medications used in dogs include fluconazole, terbinafine, ketoconazole, and itraconazole. People often talk about home remedies for dog yeast infections, but most are not proven to be effective. There are no studies to confirm that feeding any of the following is beneficial in treating yeast on a dogs skin:

There are no studies to confirm that topical use of any of the following are useful in treating yeast infections in dogs: Vinegar rinses do have scientific data to support that they may be beneficial in treating yeast. Vinegar helps to change the pH of the skin to make it less favorable for yeast.

However, for shampoo treatment to be effective, the lather must sit on a dogs skin for a minimum of 10 minutes before rinsing. If you suspect that your dog has a yeast infection, consult your regular veterinarian for a diagnosis and treatment plan that is appropriate for your pet.

If your pooch is rubbing their ear or tilting their head, they may have an ear infection caused by an overgrowth of yeast. A bacterial infection is also possible and can cause the same symptoms. So it’s important for your vet to establish what kind of infection your dog has.

Unfortunately, an ear infection in your dog caused by yeast is sometimes associated with an underlying condition, such as Allergies Bacterial infection A ruptured eardrum Tumor or polyp within the ear canal A trapped object

Once your vet has determined that Fido is suffering from an ear infection caused by yeast, they might conduct tests to check for other health problems. If your dog swims or is bathed frequently, trapped water or debris in the ear canal can lead to yeast infections. Allergens like pollens, mold, dust, feathers, cigarette smoke, cleaning products, and certain foods can also lead to ear infections in a dog.

Continued You may notice your dog scratching their ear or rubbing it on the floor or on a piece of furniture. If your dog has a yeast infection of the outer ear canal, the vet might prescribe a topical antifungal ointment or cream. An infection of the middle ear is treated with systemic medications (meaning tablets or injections), though further tests and even surgery may be needed.

Yeast dermatitis or Malassezia dermatitis is caused by the fungus Malassezia pachydermatis. It is an extremely common cause of skin disease in dogs. This yeast is normally found on the skin, but its abnormal overgrowth can cause dermatitis, or inflammation of the skin.

Treatment for yeast dermatitis may be topical, oral, or a combination of both, and is based on the severity of your dog’s condition. Many dogs with greasy or oily skin will require an initial degreasing cleansing with a shampoo containing selenium sulfide or benzoyl peroxide.

In more severe, chronic, or persistent cases of yeast dermatitis, the use of oral or systemic anti-fungal medications is often required. Because these drugs have potential side effects, particularly involving the liver, close monitoring with routine blood tests is necessary. If the dog has a relapse of the fungal infection after an initial successful treatment, a higher dose of the antifungal medication will usually be required.

Most dogs with advanced or chronic yeast dermatitis are treated with a combination of oral and topical treatment. While the condition usually requires long-term treatment, the majority of cases respond favorably and the itching is reduced within a week of beginning therapy. “In cases with underlying allergies or immune compromise, the prognosis is based on the ability to control those conditions.”

Yeast dermatitis is an inflammatory skin condition that occurs fairly regularly in dogs, especially in skin folds, ears, between paw pads or in other hot, humid areas of their body. These conditions encourage yeast to reproduce at increased rates until it becomes an overwhelming issue.

Skin

Yeast infections can occur anywhere on a dog’s skin, including the belly.

Skin and Paws

Cytology is also used to diagnose yeast on the skin.Treatments for yeast infections on the skin can 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.

What Causes Yeast Infection of the Ear?

A dog’s ear canal plunges downward and then away from the ear opening (it is shaped like a “L”). That gives yeast a favorable environment in which to grow.

If conditions on the skin change or if the immune system is suppressed, these bacteria and fungi can cause infection. These types of infections are termedA common cause of a yeast skin infection is an increase in the amount of oils produced on the skin. This is most frequently associated with allergic skin disease. Another common cause of excess skin oils isSome dogs have an immune deficiency making them ineffective at fighting yeast infections resulting in chronic infection. Dogs that receive immunosuppressive drugs such as corticosteroids (steroids) may also be unable to effectively prevent yeast infections, so may develop a chronic yeast infection.Yeast dermatitis is not contagious; your dog did not get this infection from another dog. Opportunistic yeast infections often recur unless the underlying allergy or skin condition is controlled.There are certain breeds thought to be genetically predisposed to developing yeast infections.
