Valley Fever In Dogs: Things You Need to Know

Dogs that come into touch with fungi or are diagnosed with a fungal illness might become severely unwell. The Valley Fever is a sickness caused by a specific form of fungus. Coccidioides immitis is the causative fungus; hence Valley Fever is also known as coccidioidomycosis. The fungus is a soil-dwelling organism that thrives in hot, desert settings. This fungus thrives in the states of Arizona, Nevada, New Mexico, Utah, Texas, and California. Additionally, it is widespread in Mexico and South and Central America. The disease is more widespread during the summer and late autumn.

How does your dog catch valley fever?

Dogs only contract Valley Fever in their lungs, and it is not transferable to humans or other dogs. Only the inhalation of fungal spores can induce Valley Fever; a strong cough cannot allow the infection to spread. Valley Fever is a fungal infection that affects the lungs in dogs. This is frequently seen in various desert-like locations here in North America.


Due to the prevalence of the fungus that causes valley fever in desert environments, residents of such regions should be especially vigilant in recognizing its signs. This disease can manifest in two distinct types, each of which presents differently:

Primary Valley Fever

Three weeks after an initial encounter with the fungus, primary valley fever in dogs typically manifests, most notably as a persistent cough. This is quickly followed by a fever and a general drop in mood. You may observe that your dog has stopped eating or is suddenly listless or disinterested.

Disseminated Valley Fever

Disseminated valley fever is significantly more severe. This is due to the disease’s spread throughout your dog’s body, typically to the bones and joints. Valley Fever produces intense discomfort as it progresses. In extreme circumstances, dogs may lose the use of their legs. Untreated, it can even extend to your dog’s nerve system, a sometimes fatal development. If you have not already done so, contact an emergency veterinarian or go to the nearest emergency animal hospital as soon as you observe any signs of abnormal behavior or pain.


Both varieties of valley fever are dangerous to your dog’s health; if you see any of the symptoms, contact your vet immediately.


The typical strategy for treating Valley Fever varies according to the severity of the disease. Your veterinarian will obtain blood samples and maybe x-rays with the help of a vet radiologist to diagnose your pet, after which he or she will determine the appropriate therapy and care duration. Valley Fever is almost always treated with antifungal medicine, and its duration can range from six months to a lifetime, depending on how far the disease has developed. Typically, the earlier this disease is diagnosed, the shorter the treatment will be.

To Wrap It Up
