Mycoses are diseases that result from fungal infecdtions. They are as unpleasant as they sound. Canines sometimes contract mycoses through inhalation of spores in the environment or in the dirt. One example of a mycosis is the progressive ailment mycosis fungoides; another is coccidioidomycosis. Both are potentially deadly.

Mycoses in Dogs

Mycoses in dogs are often categorized by the location of their infections. Deep mycoses in canines are systemic. Moderate-depth mycoses are subcutaneous. If a mycosis isn't deep, it's categorized as being superficial, according to Sue Paterson, author of the "Manual of Skin Diseases of the Dog and Cat." Superficial mycoses, for instance, affect the top portions of canines' claws, skin and coats.

Mycosis Fungoides

Mycosis fungoides is a deadly type of mycosis. Although it's a relatively uncommon condition, it appears more frequently in elderly dogs. It's also rare in cats. If a dog is between 9 and 12 years old, his chances of developing the mycosis are higher than those of younger canines. As far as breed and gender go, however, no dogs are more vulnerable to mycosis fungoides than any others. Mycosis fungoides involves the emergence of cancers in dogs' skin. These cancers are typically triggered by irregularities with the immune system cells -- lymphoid cells. When dogs have this mycosis, they often exhibit symptoms such as skin redness and intense itchiness.


Coccidioidomycosis, too, is a type of life-threatening mycosis that occasionally affects dogs. This ailment is a reaction to a fungus known as Coccidioides immitis. If a dog inhales this fungus, he might develop coccidioidomycosis. This frequently triggers issues with breathing in dogs. Other common symptoms of this mycosis include exhaustion, fever, issues walking, corneal inflammation, severe loss in weight and open sores on the skin. Cats also can experience this form of mycosis.


Blastomycosis is yet another mycosis that appears in the canine world. This mycosis is triggered by Blastomyces dermatitidis, which is often found in dirt and rotting wood. Male canines are especially prone to the mycosis, although female dogs can get it, too. Blastomyces dermatitidis flourishes in damp locales such as marshes or lakes. When dogs have blastomycosis, they frequently display indications such as appetite loss, fever, problems breathing, gasping and lesions on the skin. If you're concerned that your dog might have any mycosis, take him to the veterinarian without delay. A veterinarian can analyze your pet's situation and decide which type of management is optimal for him. The vet may prescribe antifungal medicine, surgery or other alternatives, depending on the specific mycosis.
