Thanks. Now I want to murder the parents.
"Although fungal infections are less common than either bacterial or viral infections, these infections can be just as serious. Fungal infections may occur due to contact with other animals, from the environment, or as a result of the overgrowth of fungi (yeast) that are naturally present in and on your dog's own body. There are two main categories of fungal infections that your dog could be diagnosed with, systematic fungal infections which affect your dog's major body systems, and localized fungal infections that are typically seen on your dog's skin or external feature."
Dog moss? I have never heard of this term.
