Pneumonia in Leopard Geckos: Respiratory Infection Signs and Treatment
- See your vet immediately if your leopard gecko has open-mouth breathing, visible mucus, repeated wheezing or clicking, or severe lethargy.
- Pneumonia in leopard geckos is a lower respiratory infection affecting the lungs. It is often linked to husbandry stress, especially temperatures outside the preferred range, poor sanitation, or ongoing upper airway disease.
- Common warning signs include noisy breathing, discharge from the nose or mouth, reduced appetite, weight loss, and holding the head elevated to breathe more easily.
- Treatment usually combines a reptile exam, husbandry review, and prescription medication from your vet. Some geckos also need radiographs, culture testing, fluids, assisted feeding, nebulization, or hospitalization.
- Typical 2026 U.S. cost range for diagnosis and treatment is about $150-$900 for mild to moderate cases, and $800-$2,000+ if advanced imaging, repeated visits, or critical care are needed.
What Is Pneumonia in Leopard Geckos?
See your vet immediately if your leopard gecko is breathing with an open mouth, making repeated clicking or wheezing sounds, or has mucus around the nose or mouth.
Pneumonia is a respiratory infection that affects the lungs. In leopard geckos, pet parents may first notice it as a "respiratory infection," but the problem can range from irritation in the upper airways to deeper infection in the lungs. Reptile respiratory disease may involve bacteria, fungi, parasites, viruses, or mixed infections, and husbandry problems often make infection more likely or harder to clear.
Leopard geckos are adapted to an arid environment. Merck lists a preferred optimal temperature zone of about 77-86 F and humidity around 20-30% for this species, so a cool enclosure, chronically damp conditions, poor ventilation, or dirty surfaces can add stress and weaken normal defenses. A gecko that is too cold may not mount a normal immune response or metabolize medications as expected.
Because reptiles often hide illness until they are quite sick, pneumonia can become serious fast. Early veterinary care gives your vet more options, including conservative outpatient treatment for stable cases and more intensive support for geckos that are struggling to breathe.
Symptoms of Pneumonia in Leopard Geckos
- Open-mouth breathing
- Wheezing, clicking, popping, or crackling sounds
- Mucus, bubbles, or discharge from the nose or mouth
- Labored breathing or exaggerated chest and throat movements
- Lethargy or weakness
- Reduced appetite or weight loss
- Holding the head elevated or stretching the neck to breathe
- Frequent gaping outside of basking behavior
Mild early signs can be easy to miss. A leopard gecko may still eat at first, even with a developing respiratory infection. Worry more if signs are repeated, getting worse, or paired with appetite loss, weight loss, or visible discharge. Open-mouth breathing, severe effort to breathe, or collapse are emergencies and should not be monitored at home.
What Causes Pneumonia in Leopard Geckos?
Pneumonia is usually not caused by one single factor. In many leopard geckos, infection develops after stress or husbandry problems weaken the respiratory tract. Common contributors include temperatures that stay below the species' preferred range, poor ventilation, dirty enclosures, chronically wet substrate or hides, and humidity that stays too high for an arid species. Husbandry history matters so much that reptile references specifically note it as part of the diagnostic workup.
The infectious part may involve bacteria, fungi, parasites, viruses, or a mixed infection. Sometimes a gecko starts with irritation or an upper respiratory problem and then develops deeper lung involvement. Mouth infections, retained shed around the nostrils, inhaled irritants, and unsanitary water or enclosure surfaces may also play a role.
Leopard geckos can also become more vulnerable when they are already stressed by transport, overcrowding, poor nutrition, recent breeding, or another illness. That is why treatment is not only about medication. Your vet will usually want to correct the environment at the same time, because antibiotics alone may not work well if the enclosure remains too cool, damp, or dirty.
How Is Pneumonia in Leopard Geckos Diagnosed?
Your vet will start with a physical exam and a detailed husbandry review. Expect questions about daytime and nighttime temperatures, how you measure humidity, substrate, cleaning routine, recent changes, appetite, weight, and whether you have noticed discharge or noisy breathing. In reptiles, this history is a key part of diagnosis because environmental problems often drive disease.
Diagnostic testing depends on how sick your gecko is. Radiographs can help your vet look for fluid, inflammation, masses, or other changes in the lungs. In some cases, your vet may recommend a tracheal wash or lung wash, cytology, or culture and sensitivity testing to identify the likely organism and choose medication more precisely. If another illness is suspected, your vet may also suggest fecal testing, bloodwork, or oral exam findings to look for stomatitis or systemic disease.
Not every gecko needs every test. A stable gecko with mild signs may start with an exam, husbandry correction, and targeted treatment. A gecko with severe distress may need oxygen support, warming, imaging, and hospitalization first. The goal is to match the workup to the gecko's condition and your family's practical limits while still giving your vet enough information to treat safely.

Questions to Ask Your Vet About Pneumonia in Leopard Geckos
Bring these questions to your vet appointment to get the most out of your visit.
- Do my gecko's signs suggest upper airway disease, pneumonia, or another breathing problem?
- What enclosure changes should I make today for temperature, humidity, ventilation, and cleaning?
- Does my gecko need radiographs now, or is it reasonable to start with an exam and treatment plan first?
- Would a culture or airway wash change the medication choice in this case?
- What signs mean the condition is worsening and needs emergency re-evaluation?
- How should I monitor weight, appetite, and breathing at home between visits?
- Is assisted feeding or fluid support needed, and can you show me the safest way to do it?
- What is the expected cost range for the next step if my gecko does not improve within a few days?
How to Prevent Pneumonia in Leopard Geckos
Prevention starts with husbandry. Leopard geckos do best in an arid setup with a proper temperature gradient and measured humidity, not guesswork. Merck lists a preferred optimal temperature zone of about 77-86 F and humidity around 20-30% for leopard geckos, while some clinical care sheets allow a somewhat broader range if the enclosure stays dry and well ventilated. Use reliable digital thermometers and a hygrometer, and check both the warm and cool sides.
Keep the enclosure clean, remove waste promptly, wash dishes regularly, and avoid chronically damp substrate or moldy humid hides. A humid hide can help with shedding, but the whole enclosure should not stay wet. Good airflow matters too. Stagnant, dirty, or overly moist conditions can irritate the airways and support infection.
Quarantine new reptiles, avoid overcrowding, and schedule a veterinary visit early if you notice repeated yawning, wheezing, discharge, or appetite changes. Small signs are easier to treat than advanced respiratory distress. If you are unsure whether your setup is appropriate, ask your vet to review your temperatures, humidity readings, and enclosure photos during the visit.
