Blastomycosis in Dogs: Everything you need to know


Canine Blastomycosis – a term that sends a chill down the spine of every dog owner. It is a serious fungal infection that can pose significant health risks to our beloved canine companions.

Let’s delve deeper into understanding this condition, its causes, symptoms, diagnosis, and treatment options, equipping ourselves with knowledge to protect our four-legged friends.


What is Blastomycosis?

Blastomycosis is a systemic fungal infection caused by the organism Blastomyces dermatitidis. The fungus thrives in moist, acidic soil enriched with decaying organic matter. Dogs, especially those living in endemic areas such as the Mississippi, Ohio, Missouri, and Tennessee river valleys, are particularly susceptible.


How do Dogs Contract Blastomycosis?

Dogs contract Blastomycosis primarily through inhalation of the fungal spores. These microscopic particles become airborne when soil or decaying matter containing the fungus is disturbed.

Once inhaled, the spores transform into yeast and multiply, causing infection. While less common, the infection can also occur through open wounds that come into contact with spore-infested soil or water.


Symptoms of Blastomycosis in Dogs

The signs of Blastomycosis in dogs can vary greatly, depending on the organs affected. Here are some common symptoms:

  1. Respiratory issues: Coughing, difficulty breathing, and exercise intolerance
  2. Eye problems: Inflammation, redness, discharge, and even blindness
  3. Skin lesions: Ulcers, nodules, and draining tracts
  4. Lameness: Due to bone involvement
  5. General symptoms: Weight loss, loss of appetite, and lethargy.


Diagnosing Blastomycosis in Dogs

Diagnosis of Blastomycosis involves a series of tests, including a complete blood count (CBC), biochemical profile, urinalysis, and chest X-rays. However, definitive diagnosis usually requires identification of the organism from affected tissues or secretions.

Treatment and Prognosis of Canine Blastomycosis

Treatment typically involves antifungal medication like Itraconazole, which is administered for several months. Prognosis varies based on the severity and progression of the disease. Early detection and treatment are crucial for a favorable outcome.

Preventing Blastomycosis in Dogs

Prevention of Blastomycosis involves minimizing your dog’s exposure to areas with a high likelihood of harboring the fungus, like swampy regions or sites with a lot of decaying wood and leaves.


The Impact of Blastomycosis on a Dog’s Quality of Life

Blastomycosis can significantly affect a dog’s quality of life, especially if it is not diagnosed and treated promptly. However, with early detection, appropriate treatment, and supportive care, most dogs can recover and lead a normal, happy life.

Raising Awareness about Canine Blastomycosis

Awareness is our most potent weapon against Blastomycosis. By educating ourselves and others, we can ensure our canine companions live the healthiest lives possible.



In summary, Blastomycosis is a serious but treatable disease. As responsible dog owners, we must stay vigilant for any unusual symptoms, seek timely veterinary care, and take preventive measures to protect our furry friends.





1. Can humans get Blastomycosis from dogs?

Humans can contract Blastomycosis, but not directly from dogs. Both humans and dogs get the infection from the same source – the Blastomyces fungus present in the environment.

2. What is the incubation period for Blastomycosis in dogs?

The incubation period for Blastomycosis in dogs typically ranges from a few days to several weeks. However, symptoms may not appear until several months post-infection in some cases.


3. Can Blastomycosis in dogs be prevented?

While there’s no guaranteed way to prevent Blastomycosis, minimizing your dog’s exposure to environments where the Blastomyces fungus thrives, such as areas with moist soil and decaying organic matter, can help reduce risk.


4. Can Blastomycosis recur in dogs?

Yes, Blastomycosis can recur in dogs, especially if the initial course of treatment was not completed, or if the dog is re-exposed to the fungus.


5. How is Blastomycosis different from other fungal infections in dogs?

Blastomycosis is a systemic infection, meaning it can affect multiple body systems, making it potentially more severe than some other fungal infections. It also requires specific diagnostic tests for accurate identification.


6. Are certain breeds more susceptible to Blastomycosis?

While Blastomycosis can affect any breed, hunting and sporting breeds that spend more time outdoors in endemic areas may have a higher risk due to increased exposure.


7. What should I do if I suspect my dog has Blastomycosis?

If you suspect your dog has Blastomycosis, it’s crucial to seek veterinary care immediately. Early diagnosis and treatment can significantly improve the prognosis.

By understanding Blastomycosis in dogs, we can ensure the well-being of our furry companions. Constant vigilance, timely intervention, and spreading awareness are the keys to combating this disease.
