When you live in or around arid regions—and your dog starts coughing, limping, or seeming low-energy—you may suspect valley fever in dogs. This fungal illness, caused by Coccidioides, hides under clear symptoms until it’s well underway. The good news? With knowledge and care, many pups recover well.
In this post, you’ll learn what doctors watch for, safe home remedies, a breakdown of valley fever in dogs treatment, and tips to keep your dog happy during recovery—all in a comforting, conversational tone.
What Is Valley Fever in Dogs?
Valley fever in dogs, also known as coccidioidomycosis, starts when dogs inhale dust-borne spores. These spores travel to the lungs and can enter the bloodstream, spreading to bones, skin, and joints. While it can improve on its own, many dogs need medical help—so staying informed is vital.

How Do Dogs Get Valley Fever?
Dogs breathe in microscopic fungal spores in dry soil environments. Dusty yards, digging, or unhygienic spaces increase exposure. While cats can also contract valley fever in cats, dogs are more frequently diagnosed due to their curious habits and time outdoors.
Symptoms of Valley Fever in Dogs to Watch
Here are the most common signs associated with valley fever:
- Persistent cough, often with fever
- Limping or sore joints—dog may jerk the leg up
- Lethargy & loss of appetite
- Lumps or swelling on limbs or skin
- Eye issues (cloudiness or discharge)
If your dog shows any combination of these, it’s time to call the vet. Don’t let poor appetite or low mood hold you back—early testing helps recovery.
Diagnosing Valley Fever in Dogs
Your vet will likely perform:

- Blood tests to detect valley fever antibodies
- X-rays to look for lung or bone infection
- Sampling lumps/fluids to confirm spore presence
Once confirmed, your vet can recommend the best plan. Keep in mind: dog valley fever rarely infects humans through contact; it’s inhaled spores—not cuddling—that spread the fungus.
