Rabbit snuffles and runny nose
Repeated sneezing, a runny or crusty nose, or 'snuffles' in a rabbit usually signals an upper respiratory infection and needs veterinary care — urgently if your rabbit is also breathing hard, off its food, or lethargic. Rabbit respiratory infections can become serious, so they need a vet rather than waiting it out. Note any discharge on the front paws from wiping the nose.
Fast answer for owners
- Go now if: Nasal discharge with breathing effort, blue lips, not eating, lethargy, fever-like signs, eye discharge, or severe congestion
- Call today if: Sneezing or mild discharge while eating normally and breathing comfortably
- Do not: Do not use leftover antibiotics; do not put oils in the nose; do not delay if breathing effort appears
- Tell the vet: Discharge colour, sneezing, breathing effort, appetite, eye signs, dental history, housing ventilation, and other rabbits affected
Go to a vet now if
- Laboured or open-mouth breathing with the discharge
- Not eating or very lethargic
- Thick coloured discharge with distress
Call a vet today if
- Sneezing with clear discharge, still eating well
- Matted fur on the inside of the front paws
Why nasal discharge and snuffles happen
Read this sign as a pattern, not as a single snapshot. Appetite, droppings, posture, breathing, temperature, pain, urine, movement, and behaviour all matter. If the sign is sudden, worsening, or combined with not eating, no droppings, collapse, coldness, breathing trouble, severe pain, trauma, or toxin exposure, call a rabbit-savvy or exotic vet now.
Common causes to consider
- upper respiratory infection, dental-root disease, tear-duct blockage, dusty bedding, ammonia, foreign bodies, or stress-related flare-ups
- thick white or yellow discharge, matted paws, sneezing fits, noisy breathing, or open-mouth breathing indicating more than irritation
- tooth-root disease pushing into the nasal passages or tear duct
Age, breed, and lifestyle nuance
- Lop and dwarf rabbits are prone to dental and skull-shape issues affecting tear ducts and breathing.
- Dusty hay, damp housing, and poor ventilation can worsen signs quickly.
- Baby, senior, and immunocompromised rabbits have less reserve when breathing effort rises.
What to tell the vet
- When the sign started, whether it is constant or intermittent, and whether it is getting worse.
- Last normal food, water, urine, and droppings; bring photos of unusual stool, urine, wounds, discharge, or posture.
- Recent diet change, moult, heat, cold, travel, bonding stress, surgery, trauma, toxins, medicines, plants, fabric, carpet, or chemicals.
- Your rabbit's age, weight, breed if known, sex and neuter status, chronic conditions, and current medications.
What not to do before the vet call
- Do not give human medicine, leftover pet medicine, gut stimulants, antibiotics, or pain relief unless a vet prescribed it for this exact episode.
- Do not force-feed if your rabbit is collapsed, choking, severely weak, bloated, struggling to breathe, or suspected of having a blockage.
- Do not wait overnight for go-now signs. Keep your rabbit quiet in a padded carrier and call while preparing to travel.
What the vet actually checks
- assess breathing effort before stressful handling, then examine nose, eyes, teeth, jaw, ears, lungs, weight, and hydration
- use nasal or eye samples, dental imaging, skull radiographs or CT, and culture when indicated
- provide oxygen if needed, clear discharge safely, choose rabbit-appropriate medication, and address dental or housing contributors
Owner observations that change urgency
Before you leave or while another person calls, note the details that make this page more specific for the clinic. These observations should not delay travel when go-now signs are present, but they help the vet judge risk quickly.
- whether discharge is clear, white, yellow, thick, one-sided, or paired with eye watering
- whether front paws are matted from wiping the nose
- whether hay dust, litter ammonia, damp housing, or another sneezing rabbit is present
Source-backed safety note
VCA describes rabbit respiratory disease as requiring veterinary diagnosis because discharge can involve infection, teeth, or environmental factors. Primary source.
Recovery support after veterinary assessment
After a veterinarian has assessed the emergency risk and given a plan, recovery support may include warmth, hydration, hay intake, assisted feeding, grooming, litter hygiene, movement changes, or products positioned for appetite and gut-rhythm support. Do not use supplements, food changes, RodiCare, WOOLY, or home care as a replacement for emergency assessment.
Frequently asked questions
Is clear discharge less serious?
It may be irritation, but persistent or recurrent discharge still deserves a call.
Is white discharge urgent?
Thick discharge with appetite loss, lethargy, or breathing effort is urgent.
Can snuffles spread?
Some infections can spread; ask how to protect bonded rabbits without causing stress.
Should I steam the bathroom?
Do not delay care with home steam when breathing effort is visible.

Page-specific owner FAQ
Is clear discharge safe to monitor?
Call if new or persistent, especially with appetite or breathing changes.
Can I use old antibiotics?
No. Rabbit antibiotic choice is species-specific and exam-dependent.
