Many Russian tortoise owners assume that a runny nose or wheezing is just a minor irritation, but these signs often point to a serious respiratory infection. In reality, respiratory infections are common in this species due to improper husbandry, especially low temperatures or high humidity.
Our editorial team explains the key signs specific to Russian tortoises, so you can act quickly to help your pet recover. Recognizing symptoms early and correcting environmental factors are crucial for successful treatment.
Common Signs of Respiratory Infection in Russian Tortoises
Russian tortoises with a respiratory infection often show nasal discharge, which may be clear or bubbly at first but can become thick and yellow or green. You might also notice open-mouth breathing, wheezing, or clicking sounds when the tortoise breathes. Lethargy is another key sign: the tortoise may sleep more, move less, and show little interest in food.
Other symptoms include swollen or puffy eyes, a reduced appetite, and weight loss. In severe cases, the tortoise may extend its neck and gape, struggling to breathe. These signs can develop quickly, so daily observation is important.

Why Russian Tortoises Are Prone to Respiratory Infections
Russian tortoises originate from arid, rocky regions of Central Asia, where temperatures can fluctuate but are generally warm and dry. In captivity, they require a basking spot around 95 degrees Fahrenheit and a cool side around 70 degrees. If ambient temperatures fall below 65 degrees for extended periods, their immune system weakens, making them susceptible to respiratory infections.
High humidity, poor ventilation, and damp substrate also contribute to illness. Russian tortoises need low humidity (below 50%) and a dry environment. Overly moist conditions can lead to fungal or bacterial growth in the respiratory tract. Additionally, stress from improper handling, overcrowding, or a poor diet can lower resistance.
Immediate Steps to Take If You Suspect a Respiratory Infection
If you notice any signs, the first step is to check and correct your tortoise’s habitat. Ensure the basking temperature is accurate and that the enclosure has a warm side and a cool side. Remove any damp substrate and replace with dry material like aspen or paper. Increase ventilation but avoid drafts.
Offer your tortoise a shallow warm soak (around 85 degrees) for 15 minutes daily to help with hydration, but do not force it. Do not attempt to treat the infection with over-the-counter remedies; these can be harmful. A vet experienced with reptiles should evaluate the tortoise, as antibiotics may be needed. Keep the tortoise warm and quiet during transport.
Long Term Prevention of Respiratory Problems
Preventing respiratory infections starts with stable, appropriate temperatures. Use a thermostat to regulate heat sources and monitor with a digital thermometer. Maintain a day night temperature drop but not below 65 degrees. Provide UVB lighting to support vitamin D synthesis and immune health.
Feed a diet high in fiber and low in protein, consisting of dark leafy greens, weeds, and grasses. Avoid fruits and high-protein foods. Keep the enclosure clean and dry, spot cleaning daily and fully changing substrate monthly. Quarantine any new tortoises for at least 90 days before introducing them to prevent disease spread.
