Malassezia is a genus of fungi, a yeast that is usually found in human and animal skin surfaces. Malassezia pachydermatitis is the most common type of malassezia found on both dogs and cats. Normally, these yeasts do not cause any harm. However, malassezia infections can occur when the number of malassezia increases. Malassezia infections are opportunistic, which means that they occur due to the appearance of another pathology.

Malassezia in dogs: causes
A we’ve already mentioned, malassezia in dogs is genus of fungi, part of normal skin flora. This fungi is beneficial because it inhibits the presence of other organisms that would, if not for the malassezia, be more pathogenic. Skin imbalances that can increase humidity, heat, sebum or immunity can cause malassezia to proliferate, worsening and/or complicating the case at hand. These such malassezia causes include:
- Hormonal disease, like hypothyroidism.
- Prolonged use of corticosteroids or antibiotics.
Canine malassezia symptoms include:
- Crusty scale-y skin.
- Skin thickening.
- Seborrhea (dog dandruff), with an increase in the production of sebum, which gives the dog a characteristic musty rancid smell.
