Rabbit Rhinitis: Why Your Rabbit Has a Runny Nose or Sneezing

Rabbit rhinitis means inflammation inside the nose and upper airways. Pet parents often notice it first as sneezing, a wet nose, or dried discharge on the front paws where a rabbit has wiped its face. In rabbits, this problem is commonly grouped under the term snuffles, especially when infection is involved.

Rhinitis is not one single disease. It is a sign that something is irritating or infecting the nasal passages. Bacteria such as Pasteurella multocida are common contributors, but other bacteria can be involved too. Some rabbits also develop similar signs because of dental disease, since the roots of the upper teeth sit close to the nasal and sinus areas.

This matters because rabbits rely heavily on breathing through their noses. Even a problem that starts as mild sneezing can become more serious if swelling, thick mucus, pain, or poor appetite develop. A rabbit that cannot smell well may also eat less, and that can quickly lead to gastrointestinal slowdown.

If your rabbit has a runny nose or repeated sneezing, it is worth having your vet look for the underlying cause rather than assuming it is a minor cold.

Bacterial infection is one of the most common causes of rhinitis in rabbits. Pasteurella multocida is the organism most people associate with snuffles, but it is not the only one. Other bacteria, including Bordetella, Pseudomonas, and Staphylococcus, may also be involved. Some rabbits carry bacteria without obvious illness, then develop symptoms when stress, crowding, or another health problem lowers their defenses.

Not every runny nose is an infection. Dental disease is a major noninfectious cause because overgrown teeth or infected tooth roots can press into nearby sinus and tear duct structures. That can lead to sneezing, nasal discharge, watery eyes, facial swelling, or chronic recurring signs that do not fully improve with medication alone.

Environmental irritation can also play a role. Dusty hay, poor ventilation, smoke, aerosol sprays, and aromatic wood shavings such as cedar or pine may irritate a rabbit's sensitive airways. Less common causes include foreign material in the nose, facial trauma, nasal abscesses, and tumors or other abnormal tissue growths.

Because several very different problems can look similar at home, the most helpful next step is not guessing the cause. It is having your vet sort out whether the issue is infectious, dental, environmental, or obstructive.

Your vet will usually start with a full history and physical exam, including listening to breathing, checking the nose and eyes, and looking for discharge on the paws. They may also examine the mouth and jaw as much as your rabbit allows, because dental disease is a common hidden driver of chronic nasal signs.

Testing depends on how sick your rabbit is and how long the problem has been going on. Mild early cases may begin with an exam and supportive treatment plan. More persistent or severe cases often need skull or chest radiographs, bloodwork, and sampling of nasal discharge for culture and sensitivity testing. Culture helps identify which bacteria are present and which antibiotics may be more likely to work.

If signs keep returning, your vet may recommend sedation or anesthesia for a more complete oral exam, dental imaging, or advanced imaging such as CT. These tests can help find tooth root infection, sinus involvement, abscesses, foreign material, or a mass inside the nasal passages.

Diagnosis is important because treatment can look very different depending on the cause. A rabbit with irritation from bedding needs a different plan than a rabbit with chronic bacterial disease or tooth root infection.

You cannot prevent every case of rabbit rhinitis, but you can lower risk. Keep your rabbit's housing clean, dry, and well ventilated. Choose low-dust hay when possible, avoid smoke and scented sprays, and use rabbit-safe paper-based litter instead of aromatic softwood shavings that may irritate the airways.

Routine wellness visits matter too. Your vet can look for early dental disease, weight loss, eye changes, or subtle nasal discharge before the problem becomes advanced. Because tooth root disease can contribute to chronic nasal signs, regular dental checks are an important part of prevention.

Stress reduction also helps. Rabbits tend to do better with stable routines, good nutrition, and enough space to rest and move normally. If you bring home a new rabbit, ask your vet about safe quarantine practices before introductions, especially if either rabbit has sneezing or discharge.

At home, pay attention to small changes. A damp nose, crusty paws, louder breathing, or a drop in appetite may be the first clue that your rabbit needs care. Early evaluation often gives you more treatment options and may help prevent a mild problem from turning into a chronic one.
