Yeast infections in dogs are commonly caused by an overgrowth of the Malassezia organism, a type of yeast. Several factors can contribute to this overgrowth, including allergies (food or environmental), hormonal imbalances, poor grooming habits, underlying medical conditions such as hypothyroidism or Cushing's disease, and a weakened immune system. Additionally, moisture in the ears or skin folds, such as those around the tail or armpits, can create a favorable environment for yeast to thrive. It's important to consult with a veterinarian to properly diagnose and treat yeast infections in dogs.
