Why does my Hermann's tortoise have a runny nose?
A runny or bubbly nose in a Hermann's tortoise is a warning sign, not a passing sniffle, it often points to a respiratory infection (sometimes called RI or runny nose syndrome), usually triggered by being kept too cold, too damp or under stress. Keep the tortoise warm and see an exotics vet, because respiratory infections need veterinary treatment and don't clear on their own, and never let a tortoise with a runny nose brumate.
What a runny nose usually means
Clear or bubbly discharge from the nostrils is the classic early sign of a respiratory infection in tortoises. The usual triggers are husbandry stress on the immune system, an enclosure that's too cold, too damp, or too draughty, or a tortoise run down by a stressful move or poor conditions. Occasionally a little clear moisture after a soak or a drink is harmless, but persistent or bubbly discharge should always be taken seriously.
Warning signs to watch for
A respiratory infection rarely stays limited to the nose. Watch for wheezing or clicking breaths, open-mouth or laboured breathing, a foamy or gaping mouth, lethargy, and loss of appetite. A tortoise stretching its neck out to breathe or blowing bubbles from the nose is showing clear respiratory distress. The more of these signs appear together, the more urgent a vet visit becomes.
Keep it warm and see a vet
Respiratory infections don't resolve by themselves and typically need veterinary treatment, often antibiotics, so an exotics vet is the priority. In the meantime, keep the tortoise warm and well-hydrated, raise it to the upper end of its normal range so its immune system can work, ensure the basking spot reaches 32–35°C (90–95°F), and offer regular lukewarm soaks. Warmth supports recovery but is not a substitute for the vet.
Never brumate a tortoise with a runny nose
This is the one hard rule: a tortoise showing any sign of a runny nose or respiratory infection must not be allowed to brumate. Cooling down suppresses the immune system further, and an infection that was manageable can become fatal over a cold winter. Keep the tortoise warm and awake, get it treated, and only reconsider brumation once it's fully recovered and a vet is satisfied it's healthy.
When to see a vet
See an exotics vet promptly for any persistent runny or bubbly nose, and urgently if it comes with wheezing, open-mouth or laboured breathing, a foamy mouth, lethargy or loss of appetite. Respiratory infections need veterinary treatment and won't clear on their own, and never let an affected tortoise brumate.
One reading rarely tells the story. What matters is whether it's an isolated blip or part of a trend, so look at recent weight, feeding intervals, shedding, temperature and behaviour together.
baskr keeps those records in one place and watches the pattern for you, so you can see whether something has genuinely changed with your hermann's tortoise, before it becomes a problem.

Is a runny nose serious in a Hermann's tortoise?+
It can be. A persistent or bubbly runny nose often signals a respiratory infection, which needs veterinary treatment and won't clear by itself. Occasional clear moisture after a soak is harmless, but ongoing discharge should be checked by a vet.
What causes respiratory infections in tortoises?+
Usually husbandry stress on the immune system, an enclosure that's too cold, too damp or draughty, or a tortoise run down by a stressful move. Correcting temperatures and conditions helps prevent them, but an established infection still needs a vet.
Can I hibernate my tortoise if it has a runny nose?+
No. A tortoise with a runny nose or any sign of respiratory infection must never brumate, cooling suppresses the immune system and can turn a treatable infection fatal. Keep it warm and awake, get it treated, and only reconsider once it's fully recovered.
How do I treat a tortoise's runny nose at home?+
You can't fully treat it at home, respiratory infections generally need veterinary medication. What you can do meanwhile is keep the tortoise warm at the top of its normal range, keep it well-hydrated with soaks, and get it to an exotics vet quickly.
