Pneumonia in Hedgehogs: Signs, Causes, and Treatment
- See your vet immediately if your hedgehog has labored breathing, open-mouth breathing, blue-tinged gums, marked lethargy, or stops eating.
- Common signs include nasal discharge, sneezing, noisy breathing, faster breathing, weakness, and reduced appetite.
- Bacterial infection is a common cause, and Bordetella bronchiseptica is specifically reported in hedgehogs. Cold stress, poor ventilation, dusty bedding, and exposure to sick animals can raise risk.
- Diagnosis often includes a physical exam, chest imaging, and sometimes lab testing or airway samples. Early treatment improves the outlook.
- Typical US cost range for diagnosis and treatment is about $250-$1,800+, depending on whether care is outpatient or requires oxygen support and hospitalization.
What Is Pneumonia in Hedgehogs?
Pneumonia is inflammation and infection in the lungs and lower airways. In hedgehogs, it can interfere with oxygen exchange and make breathing much harder than normal. Because hedgehogs are small prey animals, they may hide illness until they are quite sick.
Respiratory disease, especially pneumonia, is reported fairly often in pet hedgehogs. Signs may include nasal discharge, sneezing, and difficulty breathing. More severely affected hedgehogs may become listless and stop eating, which is why this condition should be treated as urgent rather than something to watch at home for several days.
Pneumonia may be mild at first, but it can progress quickly. A hedgehog that seems only a little quieter than usual in the evening can be in real respiratory distress by the next day. If your pet is breathing harder, stretching the neck to breathe, or refusing food, your vet should assess them as soon as possible.
Symptoms of Pneumonia in Hedgehogs
- Nasal discharge
- Sneezing
- Noisy, rapid, or labored breathing
- Open-mouth breathing or neck extended to breathe
- Lethargy or weakness
- Reduced appetite or not eating
- Weight loss
Mild sneezing alone may not always mean pneumonia, but breathing changes, weakness, and appetite loss are much more concerning. See your vet immediately if your hedgehog is breathing with effort, breathing with the mouth open, feels cool, seems limp, or has stopped eating. In hedgehogs, these signs can worsen quickly.
What Causes Pneumonia in Hedgehogs?
Bacterial infection is one of the best-documented causes of pneumonia in hedgehogs. VCA notes that Bordetella bronchiseptica is one of the most common causes reported in this species. Because this bacterium is also involved in kennel cough in dogs, exposure to coughing or unvaccinated dogs may increase risk in some homes.
Pneumonia can also be more likely when a hedgehog is stressed or kept in poor respiratory conditions. Low enclosure temperatures, drafts, poor ventilation, and irritating bedding can all make the airways more vulnerable. Husbandry references for hedgehogs recommend warm, stable temperatures, and some exotic practices specifically advise avoiding cedar and pine shavings because they can contribute to respiratory irritation.
In some cases, pneumonia develops after an upper respiratory infection spreads deeper into the lungs. Less commonly, aspiration, underlying illness, or immune compromise may play a role. Your vet will look at the whole picture, including environment, recent exposures, and how quickly signs appeared.
How Is Pneumonia in Hedgehogs Diagnosed?
Your vet will start with a careful history and physical exam, including breathing effort, body condition, hydration, and temperature support needs. In hedgehogs, even gentle handling matters because stress can worsen respiratory distress.
Chest radiographs are commonly used to look for lung changes, although imaging can be harder to interpret in hedgehogs because the spines may obscure detail. Merck notes that radiographs can still be useful, and CT can be especially helpful for respiratory disorders when available. Depending on the case, your vet may also recommend blood work, pulse-ox style monitoring if feasible, or samples to help identify infection.
Not every hedgehog needs every test on day one. A very unstable patient may need warming, oxygen support, and initial treatment before a full workup. A more stable hedgehog may be able to have outpatient imaging and medication planning the same day.

Questions to Ask Your Vet About Pneumonia in Hedgehogs
Bring these questions to your vet appointment to get the most out of your visit.
- Does my hedgehog seem stable enough for outpatient care, or do you recommend hospitalization?
- What findings make you think this is pneumonia rather than an upper respiratory infection alone?
- Would chest radiographs change the treatment plan today?
- What home temperature and humidity range do you want me to maintain during recovery?
- Is my bedding, cage setup, or ventilation contributing to the problem?
- How will I know if the medication plan is working within the next 24 to 72 hours?
- What signs mean I should come back the same day or go to an emergency clinic?
- What is the expected cost range for the plan you recommend, including rechecks?
How to Prevent Pneumonia in Hedgehogs
Prevention starts with husbandry. Hedgehogs do best in a warm, stable environment, and VCA husbandry guidance places that range around 70-85°F. Sudden chilling, drafts, and poor ventilation can stress the respiratory tract, so it helps to monitor enclosure temperature closely and keep the habitat dry and clean.
Choose low-dust bedding and avoid aromatic wood shavings such as cedar or pine when possible, since exotic-animal references warn these materials can contribute to respiratory irritation. Regular cleaning matters, but strong fumes from cleaners can also be irritating, so rinse and dry the enclosure well before your hedgehog goes back in.
Limit exposure to sick animals, especially coughing dogs, because Bordetella bronchiseptica has been linked to pneumonia in hedgehogs. Quarantine new pets, wash hands between species, and schedule a veterinary visit promptly if you notice sneezing, discharge, or appetite changes. Early care is often the best prevention against a mild respiratory problem becoming a lung infection.
