Types of fungi in dogs

Dogs can be affected by several types of fungal infections, both on the skin and internally. Here Waggy's explains some of the most common ones:

• Dermatophytosis (ringworm): This is a fungal skin infection that affects dogs (and also humans). The fungi responsible are dermatophytes, such as Microsporum canis and Trichophyton mentagrophytes.
• Malassezia ( Malassezia pachydermatis dermatitis ): This type of yeast is part of a dog's normal skin microbiome, but can cause problems if it becomes too prevalent. It is very commonly found in ear infections (otitis).
• Candidiasis: Candida fungal infection usually occurs in moist areas of the body, such as the ears, skin folds, and mouth.
• Blastomycosis: It is an internal fungal infection caused by the fungus Blastomyces dermatitidis, which is found in humid environments such as rivers and lakes.
• Histoplasmosis: Caused by the fungus Histoplasma capsulatum , which is found in soils with organic matter, such as bird or bat droppings.
• Cryptococcosis: Caused by the fungus Cryptococcus neoformans , present in soils with bird droppings.
• Aspergillosis: Caused by the fungus Aspergillus spp ., it usually affects the nasal passages or lungs.

Most of these fungi are treated with topical or systemic antifungals, depending on the type of infection and its severity. Prevention, such as maintaining good hygiene and avoiding areas prone to fungi, is essential.

What causes fungal infection in dogs?

Fungal infections in dogs can be caused by:

• Warm, Humid Environments: Fungi thrive in warm, humid environments. If a dog gets wet frequently or lives in an environment with high humidity, he is more prone to developing fungal infections, especially in areas with skin folds or areas with poor ventilation, such as between the toes.
  
  
• Weakened Immune System: A compromised or weak immune system, whether from a pre-existing disease, infection, aging, or long-term use of medications such as steroids, can make a dog more susceptible to fungal infections.
  
  
• Allergies: Allergies to food, the environment (such as pollen or dust), or cleaning products can cause skin irritation. This can create an environment conducive to the overgrowth of fungi, such as the Malassezia yeast.

Give your pet the best with Waggy's Wellness treats with HEMP, pumpkin and Omegas 3, 6 and 9, specially designed to care for their skin and coat. These natural ingredients work in synergy to reduce skin allergies, promoting healthy skin and a shiny coat.

A delicious treat that also takes care of your pet's health!

• Poor Hygiene Conditions: Dogs that do not receive proper skin care, such as regular baths or proper cleaning of areas such as the ears and paws, can develop fungal infections.
• Skin Trauma or Wounds: Cuts, scrapes, or wounds can provide an entry point for fungi that would not normally affect healthy skin. This includes areas damaged by scratching due to allergies or itching.
• Exposure to Fungal Sources: Some fungi, such as Blastomyces and Histoplasma, are found in soil or natural environments. Dogs that spend time in areas with high concentrations of fungi, such as moist soil or contact with bird or bat feces, are at higher risk of becoming infected.
• Inadequate Nutrition: A diet deficient in essential nutrients can affect the health of the dog's skin and immune system, increasing susceptibility to fungal infections.
• Long-Term Use of Antibiotics or Steroids: Long-term use of antibiotics can wipe out the body's natural bacteria, allowing fungi, such as Candida yeast, to proliferate unchallenged. Steroids, on the other hand, can suppress the immune system, making it less effective against fungal infections.
• Predisposed Breeds: Some dog breeds, such as Cocker Spaniels, Basset Hounds and Bulldogs, are more prone to fungal infections due to skin characteristics such as skin folds or predisposition to allergies.

Symptoms of fungus in dogs

Symptoms of fungal infections in dogs vary depending on the type of fungus and the location of the infection (skin, ears, nails, or even internal organs). However, here are the general symptoms that may indicate a fungal infection:

• One of the most common symptoms is persistent itching, which may cause the dog to scratch, lick or bite the affected areas.
• Fungal infections often cause hair loss in localized or extensive areas. Hairless patches may appear, often with a circular appearance, especially in the case of ringworm.
• The affected skin may become reddish or swollen, indicating irritation and infection. In some cases, swelling may also occur.
• It is common for skin affected by fungus to become dry, scaly or thickened. In the case of Malassezia infections, the skin may become greasy or oily-looking.
• Some fungal infections, especially those caused by yeasts such as Malassezia, can produce a strong, unpleasant odor, especially in skin folds or the ears.
• In some cases, lesions, ulcers or scabs may appear on the affected areas. The lesions may be painful or irritating for the dog.
• Fungal ear infections (otitis) can cause a dark brown, yellow, or black discharge with a foul odor. The dog may also shake his head or scratch his ears constantly.
• The discomfort caused by itching and pain can cause the dog to become more irritable, anxious or lethargic.
• Fungal infections that affect internal organs (such as the lungs) can cause symptoms of general illness, such as fever, weakness, shortness of breath, and weight loss.
• The skin may have an oily or sticky texture, especially in fungal infections such as Malassezia.

If you notice any of these symptoms in your dog, it's important to take your dog to the vet for a proper diagnosis and early treatment. Fungal infections can be annoying and potentially serious if not treated promptly. If vet visits are causing stress and anxiety for your dog, consider using Waggy's CBD Olive Oil with HEMP for dogs, with prior approval from your veterinarian. Remember that the use of any HEMP product should be supervised by your pet's veterinarian. At Waggy's, we care about the health and well-being of your furry companion every step of the way.

How are fungus infections in dogs diagnosed?

Diagnosing fungal infections in dogs begins with a clinical evaluation by your veterinarian. He or she examines visible symptoms such as itching, redness, skin lesions, or ear discharge. Additionally, the dog's history, including factors such as exposure to moist environments or previous skin problems, is relevant to identifying a possible fungal infection.

To confirm the diagnosis, your veterinarian will often perform specific tests. One of the most common is a skin scraping, where a sample of the affected skin or fur is taken and examined under a microscope for the presence of fungus or yeast. Fungal cultures may also be used, which involve growing the samples on a special medium to identify the specific fungus causing the infection.

In more complicated cases or when internal fungal infections are suspected, additional tests may be necessary, such as blood tests, X-rays, or even biopsies. These tests help determine whether the fungus has spread to other organs or tissues in the body, providing a more accurate diagnosis to initiate appropriate treatment.

Treatment for fungus in dogs

Treatment for fungal infections in dogs depends on the type of fungus, the severity of the infection, and its location. In general, there are several treatment options that include topical and oral medications and changes in the dog's care:

Topical Treatments: For localized skin infections, antifungal shampoos, creams, or lotions are used. These products contain ingredients such as miconazole, clotrimazole, or ketoconazole, which act directly on the fungus. Regular medicated baths are essential to eliminate the infection and prevent it from spreading.

Oral Medications : For more severe or widespread infections, your veterinarian may prescribe oral antifungals. These medications help fight the infection from within, and are necessary when topical treatments are not sufficient. It is essential to follow the full course of treatment, which can last several weeks or even months, to ensure that the fungus is completely eradicated.

Can fungus in dogs be transmitted to humans?

Yes, some types of fungus in dogs can be transmitted to humans, especially those responsible for ringworm (dermatophytosis). This type of fungus is zoonotic, meaning it can be transmitted between animals and people. Transmission occurs through direct contact with an infected dog or contaminated surfaces, such as bedding or brushes. Humans, especially those with weakened immune systems, can develop skin lesions similar to those that appear in dogs. To prevent transmission, it is important to treat the infection in the pet quickly and maintain good personal and environmental hygiene.

Caring for a dog with fungus

• Maintain good hygiene: Bathing your dog with anti-fungal shampoos as directed by your vet is crucial to controlling the infection. Make sure to dry your dog thoroughly after each bath, especially in skin folds and between the toes, as moisture encourages fungal growth.
• Isolate the dog: If the infection is contagious, such as ringworm, it is important to keep the dog away from other vulnerable animals and people. Regularly clean and disinfect its environment (beds, toys, brushes) to prevent the spread of the fungus.
• Follow veterinary treatment to the letter: Make sure to administer all prescribed medications (topical and/or oral) for as long as your veterinarian indicates, even if symptoms improve before completing treatment, to avoid relapses.

Conclusion

Keeping your dog fungus-free is essential for their health and well-being. Through good hygiene, a clean environment, and a balanced diet, you can significantly reduce the risk of fungal infections. Remember that prevention is key, so make sure you take care of every aspect of your furry friend's life. With these simple steps, you can enjoy happy and healthy moments together with your pet. Take care of your companion and give them the love they deserve!
