Sneezing – we all do it, even our favorite furry pets! But when is sneezing normal and when is it a cause for concern in rabbits? Grab a tissue and get ready to dive deep into understanding rabbit sneezing. Whether it’s nuisance allergens or a serious snuffles infection, we’ll explore the wide range of reasons rabbits sneeze and how to tell the difference between an innocent nose twitch and more troublesome symptoms. From technique to treatment, this guide offers key insights rabbit owners need to keep their buns healthy, breathing easy, and hopping with joy!

Why Do Rabbits Sneeze?

Rabbits sneeze for a variety of reasons. Sneezing is a normal bodily function that helps clear the nasal passages of mucus, dust, pollen or other irritants. Here are some of the main reasons rabbits sneeze:

  • Irritation from dust or debris – Rabbits have very sensitive respiratory systems. Dust, pollen, hay particles or litter debris can easily irritate the nasal passages and trigger sneezing. This is especially common in newly adopted rabbits as they adjust to a new environment. Frequent cleanings and air filters can help reduce dust and allergens.

  • Upper respiratory infections – Bacteria, viruses and other pathogens can infect a rabbit's upper respiratory tract leading to inflammation, nasal discharge and sneezing. Common culprits include Pasteurella, Bordetella and Staphylococcus bacteria. Rabbits under stress or with weakened immune systems are most at risk. Antibiotics may be prescribed for bacterial infections.

  • Dental issues – Malocclusion, tooth root abscesses and other dental problems can cause pain and inflammation in a rabbit's mouth, nasal passages and sinuses. The irritation and discharge can prompt frequent sneezing. Dental exams and teeth trimming may be needed.

  • Snuffles – Also known as pasteurellosis, snuffles is a common upper respiratory disease in rabbits caused by Pasteurella bacteria. It leads to symptoms like sneezing, nasal discharge and congestion. Snuffles can be chronic or flare up when a rabbit is stressed.

  • Allergies – Rabbits can develop allergies or sensitivities to certain foods, beddings, litters or environmental irritants. Inhaling these allergens triggers an immune response causing sneezing, runny nose and congestion. Eliminating the allergen source is key.

  • Foreign object – Rabbits are curious creatures that may accidentally inhale a piece of litter, bedding or toy. Sneezing helps expel the object, though veterinary assistance may be required.

  • Nasal polyps or tumors – Abnormal tissue growths in the nasal passages or sinuses can also obstruct airflow and cause sneezing. These are uncommon in rabbits but can develop with chronic infections. Surgery may be required for removal.

  • Stress – Rabbits tend to sneeze more when stressed. Stress can weaken the immune system and make rabbits more prone to snuffles flare ups. Sneezing when excited or startled is also common. Ensuring a comfortable environment helps minimize stress sneezing.

In summary, sneezing is very common in rabbits and usually indicates irritation or inflammation in the nasal passages, sinuses or throat. It's considered normal unless accompanied by other symptoms like lethargy, loss of appetite, labored breathing or eye/nasal discharge. Monitoring for other symptoms and discussing with an exotic vet can help determine if treatment is required.

Rabbit Sneezing with Discharge

If a rabbit is sneezing frequently and has a nasal discharge, it's often a sign of an upper respiratory infection. Here's what to look out for and when to seek veterinary care:

  • Color of discharge – A clear nasal discharge is fairly normal for rabbits as they are continual nose cleaners. But a thick, discolored discharge can indicate infection. Yellow, green or brown discharge points to bacterial or fungal infection. Red discharge may signal bleeding in the nose or sinuses.

  • Consistency of discharge – A thick, tacky or profuse nasal discharge is problematic, versus a thinner clear secretion. Thick discharge is difficult to expel and can cause more irritation. Purulent (pus-filled) discharge is a sure sign of infection.

  • Unilateral vs bilateral discharge – A discharge from one nostril only indicates localized infection to that side. Discharge from both sides signals broader upper respiratory inflammation.

  • Watery eyes – Ocular discharge often accompanies nasal discharge in a respiratory infection. Profuse tearing or pus around the eyes is concerning.

  • Sneezing fits – Frequent sneezing spells of multiple forceful sneezes in a row can indicate substantial nasal irritation or obstruction. Mild occasional sneezing is less worrisome.

  • Decreased appetite and lethargy – Rabbits feeling ill from an infection tend to eat and move less. These require prompt veterinary attention.

  • Difficulty breathing – Labored breathing through the mouth signals the infection may be worsening and obstructing airflow through the nose and sinuses.

  • Fever – Elevated body temperature over 103oF indicates bacterial or fungal infection.

  • Head tilt – A head tilt along with nasal discharge can mean inner ear infection.

  • Tooth root abscess – Discharge originating from the mouth or cheek can signal an abscessed tooth root. This requires antibiotics and dental treatment.

Any thick or discolored nasal discharge lasting more than 24 hours warrants veterinary examination. Mild clear discharge may only need monitoring. Especially with snuffles prone rabbits, discharge often requires antibiotic therapy. Leaving respiratory infections untreated can lead to chronic sinusitis, pneumonia, eye damage, poor appetite and tooth decay. Prompt treatment helps rabbits breathe and feel better.

Rabbit Sneezing with No Discharge

It's common for rabbits to sneeze occasionally even when healthy. But frequent sneezing without nasal discharge can also indicate issues that need addressing:

  • Irritation from environmental factors – Dust, litter, hay particles, pollen, perfumes, chemicals and other inhalants in the surroundings can all provoke sneezing. Monitor to see if sneezing decreases after cleaning the habitat, changing litters and limiting exposures. An air purifier may help as well.

  • Dental disease – Malocclusion, molar spurs and tooth root abscesses can fester without obvious symptoms. The discomfort causes sneezing but no nasal discharge. Regular dental exams help detect underlying issues.

  • Snuffles without discharge – Past snuffles infections can cause chronic sinus inflammation, though not severe enough to produce discharge currently. Sneezing tends to come and go.

  • Stress – Rabbits sneeze more when stressed by loud noises, new environments, inadequate space and discomfort. Sneezing from stress doesn't last long but minimizing anxiety is ideal.

  • Overgrooming – Rabbits constantly groom themselves, ingesting fur that later must be sneezed out. Sneezing from fur buildup is most common in long haired breeds. Regular brushing can help reduce excess ingestion of fur.

  • Neurological disease – While rare, certain neurologic conditions like ENT inflammation or brain lesions can cause chronic sneezing with no discharge. Diagnostic imaging would be required for diagnosis.

  • Neoplasia – Benign or cancerous tumors in the nasal passages, throat or lungs are an uncommon cause of persistent sneezing without discharge. CT scans help detect masses or polyps.

  • Heart disease – Congestive heart failure can lead to fluid buildup in lungs. This irritates airways and prompts forceful sneezing. Other symptoms like lethargy and breathing issues are also present.

The main risks with frequent sneezing are irritation of nasal tissues, discomfort, and increased ingestion of mucus by the rabbit during grooming. Monitoring appetite and energy levels is wise. Scheduling a wellness exam and dental check allows a thorough evaluation of the cause. Treatment depends on the underlying reason but may include dental correction, medication, allergen avoidance and environment changes. While not an emergency, recurring bouts of sneezing without discharge do warrant further investigation to protect rabbit health.


Sneezing is very common in rabbits and not necessarily a cause for alarm. Occasional sneezing helps rabbits clear debris and keep airways clear. However frequent, forceful sneezing or sneezing accompanied by nasal discharge, lethargy or other symptoms can signal underlying issues needing veterinary attention. Monitoring for additional symptoms and being aware of a rabbit's baseline behavior helps determine when sneezing warrants a closer look. With proper care and treatment, most rabbits recover well from common causes of sneezing like respiratory infections and dental issues. Awareness of normal vs abnormal sneezing guides rabbit owners in making sure their pets stay happy and healthy.
