Quick answer: Vets sometimes perform a nasal flush under anesthesia to remove mucus, debris, or foreign objects like grass seeds, and to collect samples for testing. At home, a few drops of plain sterile saline can help loosen crusted discharge if your vet recommends it, but neti pots and forceful flushing aren’t safe for pets, and medicated human nasal sprays can be harmful.
When vets flush the nose
- Suspected foreign bodies
- Chronic nasal discharge, to clear debris and collect samples
- During rhinoscopy or treatment of fungal infections
Safe home care
- Plain sterile saline drops, only if your vet advises
- Gently wipe discharge with a damp cloth
- Humidifier or steamy bathroom
What to avoid
- Neti pots or squeeze bottles, which can push fluid into the lungs
- Medicated human nasal sprays (decongestants can be dangerous)
- Essential oils
- Forcing anything into the nose
See a vet if
- Discharge from one nostril, or bloody discharge
- Sudden violent sneezing after being outdoors
- Discharge lasting more than a few days
- Trouble breathing
