Living in Marana, Arizona, offers a unique and beautiful lifestyle, surrounded by the stunning landscapes of the Sonoran Desert. Our pets often thrive in this environment, enjoying the sunshine and open spaces. However, this unique setting also presents specific health challenges for our beloved dogs and cats. One of the most significant concerns for pet owners in Marana, Oro Valley, Tucson, and the surrounding communities is Valley Fever.
This fungal disease, scientifically known as Coccidioidomycosis, is more than just a possibility here; it's a prevalent reality. Studies estimate that approximately 6-10% of dogs residing in Pima, Pinal, and Maricopa counties will become sick with Valley Fever each year. The financial burden can also be substantial, with Arizona dog owners collectively spending an estimated $60 million or more annually on diagnosis, treatment, and follow-up care. Understanding this common, yet potentially serious, illness is crucial for protecting your furry family members. At Tangerine Pet Clinic, we understand the joys and challenges of pet ownership in the Marana area because we're part of this community too. Founded by Dr. Michele Estheimer, who grew up right here in Marana, our clinic is deeply committed to providing exceptional, compassionate veterinary care tailored to the specific needs of local pets. We know that dealing with potential illnesses like Valley Fever can be stressful, which is why we offer a unique concierge approach, designed to make your life easier while prioritizing your pet’s health. This post aims to be your comprehensive guide to understanding Valley Fever in dogs and cats – what it is, how to recognize it, how it's treated, and most importantly, how you can help reduce your pet's risk right here in the Sonoran Desert. What Exactly is Valley Fever? Valley Fever isn't caused by a virus or bacteria, but by a microscopic fungus called Coccidioides. This fungus lives naturally in the soil of specific regions, and unfortunately, our beautiful Sonoran Desert provides the perfect conditions for it to thrive: a warm, arid climate with low rainfall and relatively alkaline soil. That's why Valley Fever is endemic (commonly found) throughout the Southwestern United States, including Arizona, California's Central Valley, New Mexico, and parts of Texas. The infection process begins when the fungus, existing as a mold in the soil, dries out and breaks into tiny, lightweight spores. These spores become airborne when the soil is disturbed. Common culprits for stirring up these spores in our area include:
It's important to know that Valley Fever is generally not contagious in the typical sense. You cannot catch it from your infected pet, nor can your infected dog or cat pass it directly to other pets in the household through coughing or sneezing. The primary way infection occurs is through inhaling spores directly from the environment. While extremely rare cases of infection through organ transplants or inhaling spores from an infected wound have been documented in humans , these are not typical routes of transmission. Some owners worry about draining skin lesions sometimes seen in pets with Valley Fever. The form of the fungus present in these lesions (spherules) is not considered infectious to people or other animals. However, good hygiene is always recommended. If your pet has a draining lesion, keeping it bandaged when possible, cleaning surfaces with a diluted bleach solution, and washing your hands thoroughly after handling the wound or bandages are sensible precautions. Is Your Dog or Cat at High Risk? Key Factors for Marana Pet OwnersWhile any animal living in or visiting an endemic area like Marana can potentially inhale Coccidioides spores, certain factors increase the likelihood of exposure and the risk of developing the disease. Species Susceptibility: Dogs are significantly more susceptible to developing clinical illness from Valley Fever than other domestic animals. They comprise the vast majority of animal cases reported. Cats can also contract Valley Fever, although it is diagnosed less frequently. One study suggested that for every 50 dogs diagnosed, perhaps only one cat case is identified. Geographic Location: Simply living in the Sonoran Desert region, including Marana, Oro Valley, Tucson, and surrounding areas within Pima and neighboring counties, is the most significant risk factor. Traveling to other endemic areas also poses a risk. Lifestyle and Environment:
Spotting the Signs: Could It Be Valley Fever?One of the biggest challenges with Valley Fever is that its signs can be sneaky. Symptoms may not appear for weeks or even months after your pet inhaled the spores. Furthermore, many of the signs are vague and can easily be mistaken for other, more common ailments like kennel cough, arthritis, or general malaise. This overlap with signs of other illnesses (as discussed in our previous blog post) underscores why prompt veterinary evaluation is essential if your pet seems unwell, especially here in the Marana area. Valley Fever typically manifests in two forms: primary (affecting the lungs) and disseminated (spreading to other parts of the body). Primary Pulmonary Valley Fever (Lungs): When the infection is primarily confined to the lungs and associated lymph nodes, the common early symptoms in both dogs and cats often include :
Getting Answers: How Tangerine Pet Clinic Diagnoses Valley FeverWhen you bring your dog or cat to Tangerine Pet Clinic with concerns about potential Valley Fever, our team takes a comprehensive and meticulous approach. We start by listening carefully to your observations – when did the signs start? What changes have you noticed in appetite, energy, or behavior? We'll ask about your pet's lifestyle, outdoor activities, and any travel history outside the Marana region, as this information can be vital. A thorough physical examination follows, assessing your pet's temperature, listening to their heart and lungs, checking lymph nodes, and evaluating any areas of pain or swelling. Because Valley Fever symptoms can mimic so many other conditions, diagnostic testing is crucial for confirmation. Our veterinarians utilize a combination of tests to build a complete picture :
The Tangerine Pet Clinic Advantage: Diagnosing Valley Fever accurately and efficiently requires synthesizing information from the history, physical exam, and various tests. This complexity highlights the value of Tangerine Pet Clinic's approach.

Navigating Treatment: Partnering with Your Marana Veterinarian If your dog or cat is diagnosed with Valley Fever, treatment almost always involves prescription antifungal medications. The goal of these medications is not necessarily to kill the fungus outright, but to inhibit its growth and allow the pet's own immune system to control the infection. Antifungal Medications: Several antifungal drugs are commonly used, typically given orally as pills or capsules, often twice daily. In very severe cases, particularly requiring hospitalization, intravenous antifungals like Amphotericin B might be used, though it carries a risk of kidney toxicity (newer lipid formulations reduce this risk). Newer drugs like Voriconazole and Posaconazole, or adding Terbinafine to other treatments, may be considered for difficult or unresponsive cases. Treatment Duration & Commitment: Treating Valley Fever is typically a long-term commitment. Most pets require medication for 6 to 12 months. If the infection has spread to bones, skin, or other organs (disseminated disease), treatment often needs to be longer, potentially 12-18 months. If the brain or spinal cord is involved, lifelong medication may be necessary to prevent relapse. This long duration requires significant dedication from pet owners for consistent medication administration and follow-up care. Monitoring and Side Effects: All antifungal medications carry potential side effects, most commonly lack of appetite, nausea, vomiting, or diarrhea. Liver enzyme elevations are also possible, so regular blood tests to monitor liver function during treatment are essential. These drugs should also be used cautiously in pregnant animals due to the risk of birth defects. It's crucial to work closely with your veterinarian at Tangerine Pet Clinic to monitor for side effects and adjust treatment as needed. Supportive Care: Antifungal medication is the cornerstone, but supportive care is vital to help your pet feel better while the drugs take effect. This may include:
Relapse (return of symptoms after stopping medication) is known to occur in both dogs and humans. The exact rate in dogs isn't known but isn't uncommon. If relapse occurs, restarting medication is usually effective, but may require several more months of treatment, or potentially lifelong therapy in cases of multiple relapses.

Desert Defense: Practical Prevention Tips for Marana PetsLiving in an area where Coccidioides is endemic means complete prevention of Valley Fever exposure is virtually impossible. However, there are numerous practical steps Marana pet owners can take to significantly reduce the risk of their dogs and cats inhaling fungal spores. Prevention primarily revolves around managing your pet's environment and modifying certain behaviors. Minimize Dust Exposure: This is the most critical strategy.
Ultimately, preventing Valley Fever in our desert environment requires ongoing vigilance and proactive choices. By implementing these environmental and behavioral management strategies, you can significantly lower your pet's risk of encountering this fungal foe. Your Valley Fever Questions AnsweredNavigating information about Valley Fever can be confusing. Here are answers to some frequently asked questions we hear from pet owners in the Marana area: Q1: My dog/cat mostly stays indoors. Are they still at risk for Valley Fever in Marana? A: Yes, the risk is significantly lower for indoor-only pets, but it's not zero. Coccidioides spores are microscopic and can be carried indoors on dust particles through open windows or doors, on shoes and clothing, or even potentially circulated by air conditioning systems, especially during dust storms. Keeping pets indoors more is a recommended prevention strategy, acknowledging that even indoor pets have some level of exposure risk in endemic areas. Using good quality air filters and minimizing dust inside the home can help further reduce this risk. Q2: Is Valley Fever contagious from my sick pet to my other pets or my family? A: Generally, no. Valley Fever is contracted by inhaling fungal spores directly from the soil or dust in the environment. It does not typically spread from animal to animal or from animal to person through coughing, sneezing, or casual contact. While the fungal form found in draining skin lesions isn't considered infectious , it's always wise to practice good hygiene (like hand washing and cleaning surfaces) when caring for any sick pet, especially those with open wounds. Q3: What does my dog's Valley Fever titer result mean? A: A Valley Fever titer is a blood test that measures the level of antibodies your dog's immune system has produced against the Coccidioides fungus. The result is reported as a ratio (e.g., 1:4, 1:16, 1:64). A higher titer generally indicates a more active or widespread infection, but this isn't always the case. Some very sick dogs can have low or negative titers, while some healthy dogs with past exposure might have low positive titers. Therefore, the titer result is just one piece of information your veterinarian at Tangerine Pet Clinic uses, along with your dog's symptoms, physical exam findings, and other diagnostic tests (like X-rays or general blood work), to make a diagnosis and monitor treatment progress. Titers usually decrease as a dog recovers with treatment. Q4: Can my pet get Valley Fever more than once? Can it relapse? A: Relapse, which is the return of symptoms after treatment has stopped, is known to occur in dogs (and humans) with Valley Fever. The exact frequency isn't known, but it's considered not uncommon, especially with disseminated infections. If a relapse occurs, treatment usually needs to be restarted, potentially for several more months or even lifelong in some cases. True reinfection (getting a completely new infection from the environment after recovering from a previous one) is thought to be rare in humans, but it's currently unknown if this happens in dogs. Q5: Are there any alternative therapies or supplements that can help my pet with Valley Fever? A: While standard antifungal medication prescribed by your veterinarian is the proven primary treatment for Valley Fever , some owners ask about supportive measures. A general pet multivitamin is usually safe and may support overall well-being. Vitamin C is sometimes given alongside the antifungal Ketoconazole to help with its absorption, but you should always check with your vet before giving Vitamin C, as high doses can cause stomach upset. Good nutrition is important for any sick pet. Therapies like herbal medicine or acupuncture have not been scientifically proven to treat the Valley Fever infection itself. Some veterinarians may use these therapies in addition to conventional treatment to support the pet's overall health or immune function, but they should never replace prescribed antifungal medication. If you're interested in exploring these options, discuss them with your Tangerine Pet Clinic veterinarian.
