    Fungal Infection in Dogs: Causes, Symptoms, Prevention & Treatment

    Fungal Infection in Dogs: Causes, Symptoms, Prevention & Treatment

    Fungal infections in dogs, particularly fungal skin infections, are common and can cause significant discomfort. One prevalent type is fungal dermatitis, also known as a yeast infection or Malassezia dermatitis. While fungal dermatitis in dogs is not contagious, it can recur unless the underlying conditions are managed. Breeds like Cocker Spaniels and Dachshunds are particularly susceptible to this infection. Knowing the symptoms of fungal infection in dogs and how to treat it is crucial for maintaining your pet's health.

    Signs and symptoms of fungal infection in dogs

    Recognising the symptoms of fungal infection in dogs early can lead to more effective treatment and quicker recovery. Here are some of the most common symptoms of fungal infection to look for:

    • Persistent itching and scratching   
    • Flaky, crusty, or scaly skin around the paws, nails, neck, and other sensitive areas
    • Thickened skin with elephant-skin-like appearance
    • Hair loss in the affected areas, especially noticeable around the ears, armpits, and anal region
    • Redness and inflammation
    • Foul-smelling sticky discharge, particularly from the ears

    Causes of fungal infection in dogs

    Only by identifying the underlying causes of fungal infection in dogs, can pet parents take prompt action to address and manage these uncomfortable health conditions. Here are some of the most common causes of fungal infection in dogs:

    • Environmental exposure: 

      Yeast thrives in hot and humid conditions, making such climates a risk factor for developing fungal skin infections in dogs. This environment promotes the growth of yeast, which can lead to fungal dermatitis.

    • Contact with infected animals: 

      Dogs can contract fungal infections by coming into contact with other infected animals. This is particularly true for highly contagious fungal dog skin conditions like ringworm. Shared spaces and grooming tools can also facilitate the spread of fungus on dogs' skin.

    • Weakened immune system: 

      Dogs taking strong immunosuppressive drugs are more susceptible to fungal infections. A compromised immune system can make it difficult for your pet to fight off the overgrowth of yeast and other fungi.

    • Underlying health issues: 

      Conditions that increase the amount of oils produced on the skin, such as specific allergies or hormonal imbalances, can also create an environment where yeast can thrive and cause skin infection in dogs.

    Prevention of fungal infection in dogs

    Preventing fungal infections in dogs involves a combination of good hygiene, environmental management, and regular veterinary care. Here are some practical steps to help keep your furry friend free from fungal skin infections and other fungal dog skin conditions:

    • Regular grooming: 

      Regularly bathing your dog helps to keep their skin clean and free from excess oils that can promote yeast growth. Consistent brushing helps remove debris and dead skin cells, reducing the risk of fungus on dogs' skin.

    • Avoid contaminated areas: 

      If you live in an area prone to certain types of fungal infections, avoid letting your dog roam in high-risk environments such as damp, wooded areas or places with decaying vegetation. In case of contagious fungal infections, such as ringworm in dogs, isolate them to prevent spreading the fungus to other pets or people.

    • Routine vet check-ups: 

      Routine vet check-ups can help detect early signs of fungal infection in dogs, allowing for prompt treatment. Your vet can also help manage any underlying health problems that may increase your dog's risk of fungal skin infections.

    • Proper nutrition: 

      A well-balanced diet strengthens your dog’s immune system, making them less susceptible to infections. You can also consult your vet about supplements that may support skin health and overall immunity.

    Identifying and treating fungal infections in dogs

    Fungal infections in dogs can range from skin conditions to systemic issues affecting internal organs. Recognising the type of infection is crucial for effective treatment:

    Fungal skin infections

    • Ringworm

      Symptoms: Hair loss, itching, flaky or crusty skin, misshapen or brittle nails.

      Treatment: Medicated baths, dips, and/or oral antifungal medications. Vacuuming and disinfecting the house to prevent spread.

    • Yeast infection (fungal dermatitis)

      Symptoms: Intense itchiness, flaky or crusty skin, ear infections, and foul-smelling skin.

      Treatment: Antiseptic or antifungal drugs applied to the skin, with oral medications for severe cases. Not contagious but requires management of underlying conditions.

    Systemic fungal infections

    • Blastomycosis

      Symptoms: Coughing, weight loss, difficulty breathing, skin lesions, and enlarged lymph nodes.

      Treatment: Oral antifungal medication.

    • Cryptococcosis

      Symptoms: Lethargy, coughing, nasal discharge, eye problems, and seizures.

      Treatment: Long-term oral antifungal medications. Treatment can be challenging and may last over a year.

    Effective treatment requires accurate diagnosis and appropriate medication. Always consult your veterinarian for the best course of action for your pet’s specific condition.
