Snuffles in rabbits (pasteurellosis): symptoms, contagion, and prevention
"Snuffles" is the common name for a chronic respiratory infection in rabbits most often linked to the bacterium Pasteurella multocida, a germ that is extremely widespread in the species. Many owners only learn it exists at the first suspicious sneeze, not realising that a healthy carrier rabbit can host the bacterium for life without ever showing a visible symptom. Our health guides are gathered in the rabbit care and grooming section.
What the research on this bacterium shows
A study by DiGiacomo, Xu, Allen, Baker, and Hinton, published in 1991 in the journal Laboratory Animal Science on the natural transmission of Pasteurella multocida in rabbits, found that the bacterium spreads very efficiently through direct contact between animals, including from breeding rabbits with no apparent clinical signs at all (study on Google Scholar). This work explains why a rabbit can develop a first snuffles episode years after adoption, with no identifiable recent exposure.
Signs to watch for
Repeated sneezing, clear discharge turning purulent, front paws stained from constant nose-wiping, watery or crusted eyes, and sometimes a head tilt if the inner ear is affected are the most common signs. Noisy breathing or wheezing should prompt a quicker vet visit, since the infection can spread down into the deeper airways.
Why flare-ups are so common
Stress, a sudden temperature change, dusty bedding, or ammonia buildup in the air often reactivate an infection that had been dormant. A well-ventilated enclosure, as described in our article on what size enclosure or cage a rabbit needs, noticeably reduces how often flare-ups occur in predisposed rabbits.
Veterinary management
No treatment fully clears the bacterium once the infection has taken hold, but a targeted course of antibiotics, prescribed by an exotic-animal vet after examination, limits the severity of symptoms and helps prevent more serious complications such as a dental abscess or a deep ear infection. Some antibiotics that are routine in other species are, in fact, strictly off-limits for rabbits, a point covered in our guide to dangerous antibiotics for rabbits.
Limiting spread between rabbits
A symptomatic rabbit should be temporarily separated from any other rabbits in the household, with its bowls and toys disinfected separately, and any newly acquired rabbit ideally quarantined for two to three weeks before direct contact. This simple precaution prevents many snuffles outbreaks in multi-rabbit households.
Frequently asked questions
Is a healthy carrier rabbit dangerous to others?
Yes, it can spread the bacterium without showing any symptom itself, which makes quarantine a particularly useful precaution whenever a new rabbit joins the household.
Can snuffles spread to humans?
No, Pasteurella multocida in rabbits poses no significant risk of transmission to humans under normal contact conditions.
Does one episode mean a lifelong condition?
Often yes: once the bacterium is established, the goal of veterinary follow-up is to limit flare-ups rather than aim for full eradication. Browse all our guides on the rabbit hub.
