My healthy dog was just diagnosed with aspergillosis colonized to her lungs. She had a full workup at Washington State University-CT and Bronchoscopy with BAL. She is otherwise healthy, though had bacterial pneumonia from which she recovered. Due to the persistent cough, I took her to WSU. Have you seen this before? Have you ever nebulized for this? It is not systemic yet.
First of all, good luck with your dog's treatment! Aspergillus can certainly cause respiratory infections in dogs; based on the diagnostic tests the veterinarians at WSU performed, I suspect this is what they identified. A BAL would be common test used to identify the presence of infectious agents in the lung. It certainly sounds positive that this infection is isolated to the lungs, systemic aspergillosis is a very serious and difficult to treat infection that most commonly occurs in dogs which are immunosuppressed (either due to treatment with an immunosuppressive drug, or because the animal has what we call a primary immunodeficiency). As a microbiologist, I don't personally see patients so I don't have first hand experience with treating these types of infections. I know that there are some excellent specialists at WSU, so I suspect your dog is in very good hands!
