Valley Fever and Your Shih Tzu
If you live in Arizona you probably have heard of Valley Fever. Valley Fever is spread through inhalation of a certain type of fungus called coccidioides. The fungus responsible for Valley Fever lives in the soil. Dogs typically come in contact with Valley Fever by digging in the dirt or inhaling fungal spores during dust storms.
Not every dog that breathes in the fungal spores responsible for Valley Fever will become ill. Just like humans, some dogs are immune from the ill effects of the fungal spores. Now I will tell you a true story to make my point. My teenage son and my husband both went through a dust storm a few years ago. A couple of days later both my husband and my son came down with a fever. We thought it was a virus.
Fortunately, my husband’s fever went away within a day and he had no other symptoms. My teenage son was not so lucky. His fever didn’t go away, he came down with a cough, body aches, headaches, fatigue, etc. His symptoms were not getting any better so we took him to the doctor. The doctor thought it was just a virus as well.
Unfortunately, it wasn’t a virus. The symptoms were sticking around long term. My son was miserable. We went from doctor to doctor without answers. His chest and joints hurt so bad at this point he didn’t want to leave his bed. Finally, I took him to Mayo Clinic Emergency in the hope of answers. The doctor did a chest X-ray. Nodules consistent with a Valley Fever infection were present in his lungs. Blood work came back and he did have Valley Fever. We made an appointment with an Infectious Disease specialist. The specialist said my son would need to take fluconazole, an anti-fungal for about a year to fight off the infection.
As you can see from my story above, Valley Fever can be serious! Most cases go away on their own but other cases can range from fever to full-blown fungal meningitis. Our dogs are susceptible as well. As a responsible Shih Tzu breeder this is especially concerning to me. Puppies have weak immune systems and may get sick. It is important to know what symptoms to look for in your dog.
Some of the most common symptoms include:
- Dry cough
- Runny Nose
- Lethargy
- Fever
- Loss of appetite
- Weight loss
- Limping
- Seizures
Diagnosis of Valley Fever in your pet is usually done through a blood test. If the Valley Fever blood test comes back positive anti-fungal medication is typically given to kill the fungus that is making your pet sick. Medication may need to be taken for a year or more depending on the severity of the disease. Your veterinarian will monitor the healing process by taking routine blood samples that look for the specific fungus. Once clear of the fungus your dog is usually able to come off of the anti-fungal medication.
There’s currently no vaccine to protect dogs from Valley Fever. Fortunately, most dogs are immune or fight off the infection before we ever even notice something is wrong. There are treatment options available to help with recovery if your dog becomes ill. Just make sure to look out for the symptoms that suggest a coccidioides infection. Remember to seek veterinary care right away if you suspect Valley Fever. Cases that are caught early usually respond quicker to treatment.
