snuffles in rabbits — the Pasteurella SG playbook

“snuffles” is the casual name for rabbit upper respiratory infection. most cases involve Pasteurella multocida, a bacterium that lives in many rabbits’ nasal cavities at low levels but flares into infection under stress, immune suppression, or environmental triggers. SG climate adds two specific issues — humidity supports bacterial growth, and HDB enclosed spaces concentrate exposure.

the symptoms

mild end of the spectrum:

• intermittent sneezing
• clear nasal discharge, occasional
• slight crusting at the nose corners
• normal eating, drinking, energy

moderate:

• frequent sneezing (multiple times per hour)
• thicker, milky or cream-colored discharge
• nose stays consistently wet
• discharge tracks down the face, sometimes dries into a “trail”
• slight reduction in appetite

severe:

• thick yellow or green nasal discharge
• audible breathing or wheezing
• eyes watering or discharge from one or both eyes
• weight loss
• lethargy
• panting

severe presentation is an emergency. respiratory issues in rabbits can progress to pneumonia within days.

the SG vet diagnostic pathway

at the visit:

• thorough physical exam, including ear and dental exam (these conditions often overlap with snuffles)
• nasal/eye discharge culture and sensitivity testing — critical because Pasteurella has antibiotic resistance issues
• sometimes X-ray of the chest to rule out pneumonia
• blood work for older or severely affected rabbits

the culture is important. shortcut prescriptions (broad-spectrum antibiotic without culture) sometimes fail because the specific Pasteurella strain is resistant to that drug. waiting 3-5 days for culture results is usually worth it.

cost: SGD 200-500 for full diagnostics including imaging if needed.

the treatment options

based on culture results, your vet selects from:

Trimethoprim-sulfamethoxazole (Bactrim). common first-line. effective against many Pasteurella strains. 2-4 week course typically.

Enrofloxacin (Baytril). second-line if first doesn’t work or culture suggests. 3-6 week course.

Chloramphenicol. for resistant cases or pneumonia involvement. longer courses, 4-8 weeks.

Azithromycin. sometimes used. longer half-life, fewer dosing intervals.

topical/intranasal saline. clears nasal passages, reduces discomfort. can be done at home with a normal saline drops or vet-supplied solution.

anti-inflammatory. meloxicam typically. reduces nasal irritation and pain.

what to avoid: amoxicillin, ampicillin, clindamycin, lincomycin. these are fatal to rabbits — they wipe out the gut bacteria. some general vets miss this; ensure your prescription is from an exotic vet.

the chronic-condition reality

Pasteurella is often a chronic condition rather than a one-time cure. realistic expectations:

• about 30% of rabbits clear completely with one antibiotic course
• about 50% improve significantly but show occasional flare-ups, especially during humidity changes
• about 20% have chronic recurrent infections requiring multiple courses per year

rabbits with chronic snuffles can still live full lives. the goal becomes management rather than cure.

environmental changes for SG

three things significantly reduce recurrence:

1. air quality

• AC during humid afternoons reduces respiratory irritation
• HEPA air purifier in the rabbit’s room (especially helpful during haze season — see our haze guide)
• avoid all aerosol products around the rabbit (air freshener, hair spray, cleaning sprays)

2. enclosure cleanliness

• daily spot cleaning of litter
• weekly full enclosure clean
• replace bedding frequently in humidity
• avoid wood-based litters that release fine dust

3. stress reduction

• consistent routine
• minimise loud noise, sudden changes
• adequate space and exercise

SG-specific triggers

three patterns I see in SG-specific snuffles cases:

1. lop-eared breeds. the lopped ear traps humidity and moisture, supporting bacterial growth near the head. Holland Lop and Mini Lop have higher snuffles rates than upright-eared breeds. see our Holland Lop guide for related ear care.

2. AC fluctuation. rabbits whose home shifts between AC and non-AC frequently have higher stress and respiratory irritation. consistent climate matters.

3. new home / boarding stress. snuffles often flares 1-2 weeks after a rabbit returns from boarding or moves homes. plan for veterinary follow-up after these events.

the bonded pair consideration

Pasteurella is transmissible between rabbits. if one rabbit develops snuffles, the bonded partner is likely already exposed but may be asymptomatic. options:

• treat the affected rabbit, monitor the partner closely
• some vets recommend prophylactic treatment of both
• never separate bonded rabbits to “isolate the infection” — the stress causes more damage than the infection prevention

what owners often get wrong

three patterns from SG owner spaces:

• assuming “it’s just a cold.” rabbits do not get common colds. nasal discharge always indicates infection or irritation, never benign virus. always investigate
• stopping antibiotics when symptoms clear. Pasteurella requires the full course. early stoppage allows rebound and selection for resistant strains
• moving the rabbit to a more humid area “to clear their sinuses.” the opposite of helpful. dry, cool air with good circulation supports respiratory healing
