Your rabbit sneezes. There is a little clear discharge on the nose. A week later it is thick and crusted, the fur on the inside of the front paws is matted, and your rabbit is eating less. Owners often call this “a cold.” It is not. Rabbits do not catch human colds — what they develop is a bacterial respiratory infection, commonly called snuffles, and it needs a vet.
The reason to take it seriously is anatomical. Rabbits are obligate nasal breathers, meaning they breathe through the nose only. A blocked nasal airway is not an inconvenience for them; it can become a life-threatening emergency.
What Snuffles Looks Like Day to Day
The most common cause is Pasteurella multocida, with Bordetella and Pseudomonas also involved. Many healthy-looking rabbits carry Pasteurella quietly, and disease tends to appear when stress, poor ventilation or another illness tips the balance.
- Clear nasal discharge that turns thick or crusted
- Frequent sneezing and noisy, snuffly breathing
- Runny eyes or conjunctivitis
- Matted fur on the inner front paws from constant wiping
- Reduced appetite and weight loss, because eating with a blocked nose is hard
- Head tilt, ear problems or abscesses in long-standing cases
Open-mouth breathing, blue-tinged gums or a rabbit that stops eating are emergency signs — go now, not tomorrow.
Triggers You Can Actually Control
Vets often ask about housing before anything else, because the environment drives this disease. Ammonia from soiled bedding irritates the airway, dust from hay and shavings carries irritants deep into the nose, and poor ventilation keeps both in the air.
| Trigger | Why it matters |
|---|---|
| Dirty bedding, wet litter | Raises ammonia, which damages the airway lining |
| Poor ventilation | Concentrates dust, ammonia and bacteria |
| Dusty hay or shavings | Direct mechanical irritation of the nose |
| Dental disease | Overgrown roots can block tear and nasal passages |
| Stress, heat, travel | Weakens immune control of resident bacteria |
A rabbit hutch kept dry, well ventilated and cleaned regularly does more for prevention than any supplement. Switch to low-dust bedding and never let urine sit in the tray.
Treatment Is Not a Home Remedy
Antibiotics are almost always required, and choosing the wrong one is genuinely dangerous. Some drugs that are safe in dogs and cats — penicillin given by mouth, for example — can cause fatal gut disease in rabbits, because their digestion depends on a delicate bacterial balance. Never treat with leftover medication.
Your vet may also use nebulization to deliver medicine directly into the airways, plus fluids and assisted feeding if your rabbit has stopped eating. Courses often run four to eight weeks, and relapses are common; many rabbits become long-term carriers. Because snuffles spreads easily, disinfect bowls, bottles, litter trays and toys, and wash your hands between animals. Do not separate a bonded pair — the stress of separation weakens immunity further.
Why Prompt Action Matters
Snuffles is one of the few rabbit conditions where the timeline genuinely changes the outcome. Caught while the discharge is still thin, a single course of the right antibiotic often settles it. Caught late, the infection can move into the ears, the lungs or the jaw as an abscess, and those are far harder to clear. That is why the practical rule is simple: two consecutive days of sneezing or nasal discharge means a vet visit, not a wait-and-see week.
This is general information, not veterinary advice. A rabbit with nasal discharge or repeated sneezing needs an examination.
