Symptoms

• The first sign of eye yeast discharge in shih tzus is generally a dark staining of the fur below the eyes. Discharge may be clear or white to yellowish-green and is often accompanied by a sour smell.
  
  

Causes

• The large, protruding eyes of this breed can cause excessive watering of the eyes, which in turn provides a breeding ground for bacteria. Irritation from bacteria causes a yeast bloom in the eye area.
  
  

Solution

• Yeast discharge is commonly treated by medicated eye drops applied once or twice per day (depending on dosage). More severe cases may be treated with oral antibiotics.
  
  

Prevention

• Keep a shih tzu's eyes and the area around them clean and dry. Wipe excess eye discharge daily with a soft cotton pad, using a new pad for each eye. Preventing bacteria from building up is the best way to avoid yeast growth and many other eye problems.
