A rabbit eating.

Rabbits are adorable, gentle creatures that make excellent pets, but like all animals, they are susceptible to specific health problems. One of the most significant health concerns for rabbits is respiratory issues. These can range from mild to severe and, if not addressed promptly, can lead to serious complications. In this blog, we’ll explore common respiratory issues in rabbits.

Snuffles (Pasteurellosis)

Snuffles is a term used to describe a respiratory infection in rabbits, primarily caused by the bacterium Pasteurella multocida. It is highly contagious and can spread rapidly among rabbits. The disease can manifest in different parts of the respiratory system, leading to various complications if not treated promptly.

Causes of Snuffles:

  • The primary cause is the Pasteurella multocida bacterium. Other bacteria, such as Bordetella bronchiseptica, can also contribute to the condition.
  • Stress, poor diet, or underlying health issues can weaken a rabbit’s immune system, making it more susceptible to infections.
  • Poor ventilation, high humidity, and exposure to irritants like dust and ammonia from urine can increase the risk of respiratory infections.
  • Snuffles is highly contagious, spreading through direct contact with infected rabbits or contaminated objects like bedding, food bowls, and water bottles.

Symptoms of Snuffles:

  • Persistent sneezing is a common sign of snuffles.
  • Discharge from the nose, which may be clear, white, or yellow, is a typical symptom.
  • Watery or pus-filled eyes can indicate the infection has spread to the tear ducts.
  • Difficulty breathing, noisy breathing, or mouth breathing are serious signs.
  • A rabbit with snuffles may appear unusually tired and inactive.
  • Decreased interest in food and water can occur due to discomfort and illness.
  • Severe infections can lead to a condition called torticollis, where the rabbit’s head tilts to one side.

Diagnosis of Snuffles

A veterinarian will diagnose snuffles based on clinical signs and diagnostic tests.

He will thoroughly examine the rabbit’s respiratory system and take nose, eyes, or throat swabs to identify the causative bacteria.

Blood tests will assess the rabbit’s overall health and immune response. Sometimes, an x-ray may be needed to check for lung and sinus complications.

Treatment of Snuffles

Treatment for snuffles involves a combination of antibiotics and supportive care.

The vet will prescribe appropriate antibiotics to target the infection. It’s essential to complete the entire course, even if symptoms improve.

Ensure the rabbit is comfortable, stress-free, and well-hydrated. Clean any nasal or eye discharge regularly. Encourage the rabbit to eat and drink. Provide a balanced diet rich in hay, fresh vegetables, and water.

Probiotics are sometimes recommended to maintain gut health during antibiotic treatment.

Prevention of Snuffles

Preventing snuffles involves maintaining good husbandry practices and minimizing risk factors.

Keep the rabbit’s living area clean and well-ventilated. Regularly clean bedding, food bowls, and water bottles. Isolate new rabbits or those showing signs of illness to prevent the spread of infection.

Provide a calm, stable environment. Minimize changes and handle your rabbit gently. Ensure your rabbit has a balanced diet to support its immune system.


Pneumonia is an inflammation of the lungs typically caused by an infection. In rabbits, it can be life-threatening if not treated promptly. The infection can be bacterial, viral, or fungal, often following an initial upper respiratory infection that has spread to the lungs.

Causes of Pneumonia

  • The most common cause is bacterial infection, often due to Pasteurella multocida, which can also cause snuffles. Other bacteria like Bordetella bronchiseptica, Staphylococcus, and Pseudomonas can also cause pneumonia.
  • Viruses such as the Rabbit Hemorrhagic Disease Virus (RHDV) can lead to respiratory issues, including pneumonia.
  • Inhalation of food, water, or vomit can cause aspiration pneumonia.
  • Stress, poor nutrition, or underlying health issues can make rabbits more susceptible to infections.
  • Poor ventilation, high humidity, and exposure to irritants like dust and ammonia from urine can increase the risk of respiratory infections.

Symptoms of Pneumonia

  • Difficulty breathing, rapid or shallow breaths, and audible respiratory sounds such as wheezing or crackling.
  • Thick, mucous-like discharge from the nose.
  • Rabbits may exhibit coughing, which can be mistaken for sneezing.
  • Unusual tiredness and inactivity.
  • Reduced interest in food and water.
  • Elevated body temperature.
  • Blue-tinged skin, particularly around the mouth and nose, indicates a lack of oxygen.
  • Noticeable weight loss due to decreased appetite and illness.

Diagnosis of Pneumonia

Diagnosing pneumonia in rabbits involves a thorough veterinary examination, including a physical examination (The vet will listen to the rabbit’s lungs and heart for abnormal sounds), radiographs (to check for lung inflammation, fluid, or other abnormalities), blood tests (to assess the rabbit’s overall health and immune response), etc.

Treatment of Pneumonia

Treatment for pneumonia in rabbits involves a combination of medications and supportive care.

If a bacterial infection is identified, the vet will prescribe antibiotics. It’s crucial to complete the entire course of treatment. Inhaling a medicated mist can help deliver antibiotics directly to the lungs. In severe cases, providing supplemental oxygen can help ease breathing.

Ensuring the rabbit is warm, comfortable, and stress-free. Clean any nasal discharge regularly. Encourage the rabbit to eat and drink. Provide a balanced diet rich in hay, fresh vegetables, and water. Hand-feeding may be necessary.

Prevention of Pneumonia

Preventing pneumonia involves maintaining good husbandry practices and minimizing risk factors. Keep the rabbit’s living area clean and well-ventilated. 

Keep your rabbit up to date with vaccinations, especially if you live in an area where diseases like RHDV are common.

Be cautious when feeding rabbits, especially if they are young or have difficulty swallowing. Avoid force-feeding unless instructed by a vet.


Myxomatosis is caused by the myxoma virus, which belongs to the poxvirus family. This disease is highly contagious and primarily affects European rabbits (Oryctolagus cuniculus). Initially introduced in various countries as a biological control method for wild rabbit populations, it has since become a significant threat to domestic rabbits.

Causes of Myxomatosis

The myxoma virus is spread through insect vectors such as fleas, mosquitoes, and mites. It can also be transmitted through direct contact with infected rabbits or contaminated objects.

Warm weather and high insect activity increase the risk of transmission. Poor sanitation and overcrowded living conditions can also facilitate the spread of the virus.

Symptoms of Myxomatosis

Myxomatosis has a range of symptoms that can vary in severity. The disease can be acute or chronic, with the acute form being more common and deadly. 

  • Severe swelling around the eyes, nose, mouth, ears, and genital area. This is often the first noticeable sign.
  • Formation of lumps or nodules on the skin, especially around the face and genitalia.
  • Difficulty breathing due to nasal and throat swelling.
  • Watery or pus-filled discharge from the eyes leads to conjunctivitis (eye inflammation).
  • Extreme tiredness and lack of activity.
  • Reduced interest in food and water.
  • Elevated body temperature.
  • Due to the weakened immune system, secondary bacterial infections may occur.

Diagnosis of Myxomatosis

Diagnosing myxomatosis involves a combination of clinical examination and laboratory tests.

The vet will look for characteristic signs such as swelling, nodules, and eye discharge by physical examination. He will take tissue samples from nodules or lesions that can be examined under a microscope to identify the presence of the virus.

Treatment of Myxomatosis

Unfortunately, there is no specific antiviral treatment for myxomatosis. Treatment focuses on supportive care to manage symptoms and secondary infections.

Ensuring the rabbit is comfortable, warm, and well-hydrated. Isolate the infected rabbit to prevent spreading the virus to other rabbits.

Antibiotics can be prescribed to treat secondary bacterial infections that can occur due to a weakened immune system. Analgesics may be administered to alleviate pain and discomfort.

In severe cases, euthanasia may be recommended to prevent prolonged suffering, as the acute form of the disease is often fatal.

Prevention of Myxomatosis

Prevention is the best strategy against myxomatosis. Vaccination is the most effective way to protect rabbits from myxomatosis. Ensure your rabbit is up to date with its vaccinations, especially if you live in an area where the disease is prevalent.

Use insect repellents and mosquito nets to minimize the risk of insect bites. Keep your rabbit’s living area clean and free from standing water to reduce mosquito breeding grounds.

Isolate new rabbits or those showing signs of illness to prevent the spread of infection.

Respiratory Viral Infections

Respiratory viral infections in rabbits can pose significant health challenges. These infections are often contagious and can lead to severe respiratory distress. 

Rabbit hemorrhagic disease (RHDV) is a highly contagious and often fatal calicivirus. The symptoms include fever, lethargy, difficulty breathing, bleeding from the nose or mouth, and sudden death. It is transmitted through direct contact with infected rabbits, contaminated objects, and insect vectors.

While less common, other viruses can also affect rabbits’ respiratory systems, leading to similar symptoms.

There are no specific antiviral medications for most viral infections in rabbits. Treatment focuses on supportive care and managing symptoms. Preventing respiratory viral infections involves maintaining good hygiene, controlling insect vectors, and ensuring your rabbit’s overall health. 

Natural Treatments for Respiratory Problems in Rabbits

While conventional veterinary care is crucial for treating respiratory infections in rabbits, some natural treatments can complement medical treatment and help manage symptoms. These natural remedies can support your rabbit’s immune system, alleviate symptoms, and promote overall health. However, it’s recommended to consult a veterinarian before using any natural treatments to ensure they are safe and appropriate for your rabbit’s specific condition.

  1. Herbal Support

Certain herbs can boost the immune system and provide relief from respiratory symptoms:

  • Echinacea is known for its immune-boosting properties. It can help support your rabbit’s immune system in fighting off infections. Administer in small amounts as tea or in liquid form, but consult with a vet for the correct dosage.
  • Goldenseal contains natural antibacterial properties that can help combat infections. Use in combination with echinacea as a tea or in liquid form. Ensure proper dosage with veterinary guidance.
  • Chamomile has anti-inflammatory and calming properties that can help reduce respiratory discomfort. Offer chamomile tea in a shallow dish, or add it to your rabbit’s water.

  1. Essential Oils

Some essential oils have antimicrobial properties and can be used to help alleviate respiratory symptoms:

  • Eucalyptus oil is known for its respiratory benefits. Use a diffuser to disperse eucalyptus oil in the air around your rabbit’s living area. Never apply essential oils directly to your rabbit or its bedding.
  • Lavender oil has calming properties and can help reduce stress, which is beneficial during illness. Diffuse lavender oil in the air, ensuring the concentration is low, and the room is well-ventilated.
  1. Steam Therapy

Steam can help clear nasal passages and ease breathing. Create a steam tent by running a hot shower and letting the bathroom fill with steam while your rabbit sits nearby (but not in direct contact with hot water). Allow your rabbit to inhale the steam for 10-15 minutes. Ensure the room is warm but not too hot.

  1. Humidifier

Using a humidifier can keep the air moist and help ease respiratory symptoms. 

A cool mist humidifier helps keep nasal passages moist and reduce congestion. Place a humidifier in the room where your rabbit spends most of its time. Clean the humidifier regularly to prevent mold growth.

  1. Dietary Support

A healthy diet can boost your rabbit’s immune system and overall health.

  • Offer immune-boosting greens like kale, parsley, and dandelion greens.
  • Although rabbits synthesize their vitamin C, offering foods high in vitamin C, like bell peppers and strawberries, can provide additional support.
  • Probiotics promote gut health, which is closely linked to immune health. Provide rabbit-safe probiotics as recommended by your vet.
  1. Hydration

Ensuring your rabbit stays hydrated is crucial for recovery. Always provide clean, fresh water. Encourage drinking by offering water in a dish and a bottle to see which your rabbit prefers.

To encourage fluid intake, offer mild herbal teas like chamomile or peppermint (cooled).

Homeopathy for Rabbits

Homeopathy is an alternative medicine system that uses highly diluted substances intending to trigger the body’s natural healing processes. It is a great addition to the treatment plan, as it promotoes prevention, supports recovery and enhances well-being. Many pet owners and holistic veterinarians use homeopathic remedies to support the health of rabbits, including those with respiratory infections. If you are considering homeopathy for your rabbit, it’s crucial to consult a veterinarian knowledgeable about homeopathic treatments and your rabbit’s specific condition.

Here are some homeopathic remedies that are sometimes used to support rabbits with respiratory issues:

  • Aconitum Napellus (Aconite) for sudden onset of symptoms, often after exposure to cold or wind. Symptoms may include restlessness, fever, and dry cough.
  • Arsenicum Album for thin, watery nasal discharge, restlessness, anxiety, and symptoms that worsen at night. It is often used for respiratory issues with exhaustion and thirst.
  • Belladonna for high fever, bright red mucous membranes, and sudden symptoms. It is helpful for acute inflammation and congestion.
  • Hepar Sulphuris Calcareum (Hepar Sulph) for thick, yellowish nasal discharge, sensitivity to cold, and irritability. Symptoms may include a barking cough.
  • Pulsatilla for thick, yellow-green nasal discharge, symptoms that improve with fresh air, and a preference for cool environments.
