In this article, our vets at Rivergate Veterinary Clinic will provide information about Blastomycosis, also known as “Blasto”. It is a fungal infection that can affect the whole body of dogs. We will discuss its symptoms, causes, diagnosis, and treatment to help pet owners understand and manage this disease.

Blastomycosis is a fungal infection caused by Blastomyce dermatitis that can affect both humans and animals. The fungus typically enters the body through the respiratory system and settles in the small airways, where it begins to reproduce. From there, it can spread to other organs and cause further infection.

What are the symptoms of blastomycosis in dogs?

Blastomycosis symptoms in dogs can include one or more of the following, depending on which organ system is infected:

• Fever
• Weight loss
• Poor appetite
• Cough
• Lymph node swelling
• Difficulty breathing
• Limping
• Skin lesions (pimples/pustules, sometimes with draining tracts, and rash-like lesions)

Cause of Blastomycosis in Dogs

Blastomycosis is a disease that usually happens when dogs inhale airborne spores from contaminated soil that has been disturbed by human or animal activity. Dogs that engage in hunting or sporting activities are more likely to be affected since they frequent these contaminated areas.

The disease can also enter through the skin, particularly in areas with water and decomposing matter or sites that have been recently disturbed by construction.

How is blastomycosis diagnosed?

To diagnose blastomycosis, a thorough physical examination will be conducted. Since it can be confused with other ailments, it is crucial for the veterinarian to eliminate any other common conditions. Our veterinarian will conduct in-house tests, including blood, urinalysis, biopsies, and imaging (such as X-rays, Ultrasound, or CT scans). It is vital to inform the vet about the dog’s whereabouts and if they have been to high-risk exposure areas for detailed analysis.

What is the treatment for Blastomycosis in dogs?

Blastomycosis in dogs is usually treated with antifungal medications that are given orally and can last for several months. If the illness is not severe, your dog can receive treatment at home.

However, if your dog experiences difficulty breathing, hospitalization and oxygen therapy may be necessary until improvement is shown.

In severe cases where medication fails, prolonged hospital stays, intravenous medications, and additional care may be required.

Dogs with severe eye involvement may not respond well to treatment and may require topical medications.
