Yeast infections in dogs range from minor annoyances to serious recurring problems. Malassezia, the most common yeast species involved in canine infections, thrives in warm, moist environments on a dog's body. The infection typically colonizes in ears, paws, and skin folds, particularly in the groin and armpit areas where moisture accumulates and warmth persists.
These locations provide ideal conditions for yeast growth because of their naturally warm, humid nature. Dogs with yeast infections in these areas often experience discomfort and may require treatment to resolve the condition.
