You may have just seen the Aspergillus info card we posted last Wednesday. So, you may know that Aspergillus is a common mold in the environment. While we know mold affects humans, you may not have known that it affects your dogs as well.

Aspergillosis is an opportunistic fungal infection.

The two types of Aspergillus infections are nasal and disseminated. The nasal version is most common in dogs with a more elongated snout such as a German Shepherd.

The nasal version occurs when a dog sniffs an area where the spores of Aspergillus is present.

Symptoms of the nasal version include:

  • Sneezing
  • Bleeding from the nose
  • Ulcers at the tip of the nose
  • Pawing at or rubbing the nose
  • Swollen nose
  • Loss of appetite
  • Long-term nasal discharge from the nose
    • Can contain mucus, blood or pus

Fungal infections commonly go to the lungs.

Disseminated aspergillosis is when the infection spreads from the nasal cavity into the rest of the body.

These symptoms can include:

  • Fever
  • Weight loss
  • Loss of appetite
  • Vomiting
  • Spinal pain and lameness
    • This can cause inflammation of the dog’s bones and bone marrow.

Dogs with immunodeficiency are at higher risk.
