Most types of parasitic fungi grow in the soil or in decaying vegetation. Canines will then manage to ingest the fungi by ingestion, breathing in the parasites or else absorbing them through the skin.

Apergillosis
-
This type of fungus is usually found in younger dogs, and even more commonly, young dogs with long noses. The fungus is able to grow into the cranium and then infects the soft tissue of the eye.
Cryptococcosis
-
This type of fungus exists in a yeast form and not only affects the eyes, but also the nervous system of dogs. This fungus enters the canine body through inhalation or an exposed wound.
Blastomycosis
-
This fungus is found along the Mississippi River and the Great Lakes where the soil has decaying vegetation. This fungus can cause glaucoma, and retinal detachment as well as complete blindness.
Valley Fever
-
Valley Fever is a fungal disease that is most common in dry areas of the Southwest U.S. If the immune system does not destroy the fungus, it will spread to the eye tissue of the canine.
Symptoms
-
If your dog has a fungal eye infection, the fungus is most likely located in other parts of their body as well. Symptoms of this can include lethargy, bloody noses, fever and coughing.
