Guinea Pig Respiratory Infection: Symptoms, Causes, and Urgent Warning Signs
If your guinea pig is sneezing, wheezing, or breathing with any effort, this is not something to watch and wait on. Respiratory infections in guinea pigs can go from mild to fatal within 48 hours.
Why Respiratory Infections Are So Dangerous
Guinea pigs have limited respiratory reserve — even moderate inflammation can rapidly compromise their ability to breathe. A guinea pig may appear normal one day, show mild discharge and sneezing the next, and develop pneumonia and die within 48 hours. This is why any respiratory symptom in a guinea pig requires same-day exotic vet care.
Common Causes
- Bordetella bronchiseptica — carried by healthy rabbits with no symptoms; this is why rabbits and guinea pigs should never be housed together
- Streptococcus pneumoniae — can cause severe pneumonia
- Pasteurella multocida
- Contributing factors: stress, overcrowding, poor ventilation, chilling, and vitamin C deficiency
Symptoms
Early signs: sneezing (persistent), clear nasal discharge turning yellow/green, lethargy, reduced appetite.
Signs requiring immediate care:
- Labored or rapid breathing — visible effort with each breath
- Wheezing or clicking sounds when breathing
- Eye discharge alongside nasal symptoms
- Complete refusal to eat
- Hunched posture with puffed-up fur
- Blue-tinged gums or lips — oxygen deficiency, emergency
What to Do
There is no effective home treatment. Go to an exotic vet immediately — ideally within hours of noticing symptoms. Treatment includes prescription antibiotics (some safe for dogs/cats are toxic to guinea pigs — never use OTC treatments without exotic vet guidance), fluid support, syringe feeding, and possibly oxygen supplementation.
Prevention
- House guinea pigs separately from rabbits
- Ensure excellent ventilation without drafts
- Provide unlimited vitamin C through fresh vegetables (bell peppers, parsley, kale)
- Quarantine any new guinea pig 2–3 weeks before introductions
