What Are Symptoms of Dog Thrush?

Updated March 23, 2017

Thrush is another name for a yeast infection. Many different types of yeast infections exist and depend on the type of yeast causing the infection as well as its location within a dog's body. The most common form of thrush is caused by yeasts of the Candida family. Stress, disease, medication, poor nutrition, inbreeding, coats with excess oil or moisture and weak immune systems are common causes of thrush. Treatment will vary depending on the location and severity of the infection. Consult a veterinarian for diagnosis and treatment options.


Itchy paws, ears and feet are common symptoms of dog thrush. Dogs that spend a lot of time licking their paws and genitals or appear to scratch excessively at their ears may have thrush and should be seen by a veterinarian. Too much scratching or licking may cause sores that will need treatment as well. Itching in the mouth and throat is evident by what appears to be the mouth moving around a lot, or a lot of attempts to swallow to alleviate the discomfort. Dogs may also try to scratch at their face or mouth in response to internal itchiness.


Frequent drooling in dogs often signifies a mouth or throat infection, which may be thrush. This does not apply to dogs like the Saint Bernard, which is known for its drooling.

Fur and Skin Symptoms

Healthy dog coats are shiny and free of excessive grease or dryness. Flakiness, bare patches or scaliness are all symptoms of yeast infections below the skin's surface. Redness and inflammation of a dog's skin, especially the legs and feet, are signs of an infection as well.


Thrush causes an unpleasant odour from the genital area, areas of skin infection and the mouth. Bathing will not eliminate these odours. Combined with any of the other mentioned symptoms, unpleasant odours are a sure sign of a yeast infection.

Intestinal Symptoms

Bloating and gas are common intestinal symptoms, as are vomiting or diarrhoea. However, these symptoms can signify a very serious health issue that may or may not be a yeast infection. Excessive vomiting or diarrhoea indicate the need to see a veterinarian as soon as possible to ensure that your pet is treated properly and with due speed. A quick response to these symptoms is essential.

Systemic Yeast Infection Symptoms

A systemic yeast infection is one that enters the bloodstream. It is very dangerous and can become life-threatening if not treated. Symptoms of a systemic yeast infection include vomiting, diarrhoea, fever, chills and muscle pain.


Fatigue and lethargy accompanied by intestinal symptoms of bloating and gas may signify a thrush infection.
