What is Malassezia fungus?

Malassezia is a type of yeast that lives naturally on the skin of animals and humans. Although it does not normally cause problems, in conditions of humidity, heat, excess sebum or when there is an imbalance in the immune system, this yeast can increase in number. In dogs, Malassezia can cause itching, redness, hair loss, bad skin odor and, in some cases, develop dermatitis that could complicate pyoderma.

How is Malassezia transmitted in dogs?

Malassezia is not transmitted from dog to dog directly as a contagious infection, but is a fungus that normally lives on the skin of animals without causing them problems. However, factors such as a weakened immune system, allergies, wet or irritated skin, or hormonal problems can cause the fungus to grow out of control. In addition, it can proliferate if the environment is warm and humid, such as in areas with skin folds or in dogs with dense fur.

Proper skin and coat care is essential to reduce factors that promote skin microbiota imbalance. Our dog supplements like Waggy's Shine, formulated with ingredients such as salmon oil, biotin, acerola and flaxseed, can contribute to skin and coat health, providing essential nutrients for their well-being.

Factors that predispose to Malassezia in dogs

Several factors may predispose dogs to developing Malassezia infections. Common ones include:

• Weakened immune system : Dogs with diseases or treatments that affect their immune system, such as diabetes or prolonged use of corticosteroids and chemotherapy drugs, may be more prone to infections by this fungus.

• Allergies : Food or environmental allergies can cause inflammation and skin changes, creating a favorable environment for Malassezia growth.

• Damp or dirty skin : Excess moisture in skin folds or ears can encourage their proliferation.

• Hormonal problems : Conditions such as hypothyroidism can affect the normal function of the skin, increasing susceptibility to infections.

• Thick or long hair : Dogs with thick or long hair, especially if not properly groomed, may have greater difficulty keeping their skin dry and ventilated.

Preventing and controlling these factors can help keep your dog's skin healthy.
