Rabbit Runny Nose: Causes, Snuffles, and When to See an Exotic Vet

---

A runny nose in a rabbit is not something to dismiss. Unlike dogs and cats who can tolerate mild respiratory symptoms for a few days, rabbits have a fragile respiratory system — they are obligate nasal breathers, meaning they cannot breathe through their mouth if their nose becomes blocked. What starts as a minor runny nose can become life-threatening quickly if not addressed.

What Is "Snuffles"?

The term "snuffles" describes upper respiratory infections in rabbits. The most common cause is Pasteurella multocida, a bacteria that lives in the airways of most pet rabbits (AEMV Pet Care Guides, 2024). It typically only causes symptoms when a rabbit is stressed, immunocompromised, or living in suboptimal conditions. However, other bacteria — including Staphylococcus, Pseudomonas, and Bordetella — can also cause snuffles.

Symptoms of Snuffles in Rabbits

A rabbit with snuffles may show:

• White or yellowish nasal discharge (starts watery, becomes thick)
• Wet paws from wiping the nose (look for matted fur on the inside of the front feet)
• Sneezing
• Noisy breathing or snoring sounds
• Loss of appetite
• Lethargy or decreased activity
• In advanced cases: head tilt, abscess formation, or eye discharge

Because rabbits instinctively hide signs of illness, snuffles is often well-advanced by the time an owner notices symptoms.

Other Causes of a Runny Rabbit Nose

Not all nasal discharge is snuffles. A rabbit's runny nose may also be caused by:

• Dental disease: The roots of rabbit teeth are anatomically close to the nasal passages. Overgrown or infected teeth can press on the nasal ducts.
• Irritants: Dusty hay, cedar or pine bedding (avoid these), cigarette smoke, or cleaning products can cause nasal irritation and clear discharge.
• Allergies: Rarely, environmental allergens can cause clear nasal discharge.
• Abscesses: Facial abscesses in rabbits can involve the nasal area and cause persistent discharge.

When to Worry: Emergency Signs

Take your rabbit to an exotic vet (not a standard small animal vet — rabbits require specialist knowledge) if:

• The discharge is thick, white, or yellow
• Your rabbit is breathing audibly (clicking, wheezing, or bubbling sounds)
• Your rabbit stops eating — even for a few hours
• They become lethargic or sit hunched
• You notice their gums or lips look pale or bluish
• Head tilt develops alongside the runny nose

What to Do at Home

• Improve ventilation in your rabbit's living space — poor airflow worsens respiratory infections.
• Switch to low-dust, clean hay — dust-free Timothy hay is best. Avoid cedar or pine shavings as bedding.
• Clean discharge gently from the nose with a warm, damp cloth.
• Check the food bowl — a rabbit that stops eating for more than a few hours is at risk of GI stasis, which is a separate emergency.
• Do not give antibiotics without vet guidance — using the wrong antibiotic for a rabbit can kill the beneficial bacteria in their gut and cause fatal enterotoxemia.

Snuffles often requires prescription antibiotics chosen specifically for rabbits (commonly enrofloxacin or azithromycin). Treatment may be needed for several weeks.
