Wet Nose on a Rabbit: All You Need to Know

A wet nose is a key feature of any adorable rabbit, but have you ever wondered why bunnies have damp noses? That glistening moistness serves some important purposes! Rabbits’ wet noses allow them to properly regulate their body temperature and pick up scents in their environment. However, you need to be able to distinguish normal wetness from problematic nasal discharge, which can signal disease. In this article, you’ll learn all about the reasons for a rabbit’s damp nose and what to watch out for. We’ll explore how rabbits use their nose moisture to their advantage and the common respiratory conditions that could cause an overly wet nose in bunnies. Get ready to be captivated by the wonders of the rabbit nose!

Possible Reasons for a Wet Nose

A wet nose is completely normal for rabbits. In fact, rabbits are supposed to have wet noses. There are a few reasons why rabbits often have wet or damp noses. First, a wet nose helps rabbits stay cool. Rabbits do not sweat like humans do. Instead, they rely on their ears and noses to release excess heat. The moisture on a rabbit's nose helps lower their body temperature. Second, a wet nose enhances a rabbit's ability to pick up scents. Rabbits have an excellent sense of smell, which they use to monitor their surroundings. The moisture on their nose traps odor molecules, allowing them to better detect smells. Lastly, some wetness is caused by normal grooming behavior. Rabbits clean themselves frequently, and this leaves a bit of moisture on their noses. As long as your rabbit's nose does not appear overly wet or have discharge, some dampness is perfectly normal.

Staying Cool

A rabbit's wet nose plays an important role in thermoregulation. Rabbits do not have sweat glands like humans do. Instead, they rely on their ears and nose to release excess heat and cool their bodies down. When a rabbit is hot, the blood vessels in their ears enlarge and blood flows to the ears. As the blood circulates through the many blood vessels in the ears, heat gets released into the environment. The moisture or wetness on a rabbit's nose serves a similar function. The damp surface of the nose helps dissipate heat. As moisture evaporates off the nose, it takes heat with it. This evaporation has a cooling effect on the rabbit's body temperature. The nose is rich with blood vessels and allows for the release of warm blood. A drier nose would not offer the same cooling capacities. In addition, rabbits use their paws to spread saliva on their noses when hot. The saliva increases evaporative cooling on the nose's surface. So in summary, the wet nose is an effective means for temperature regulation in rabbits. The moisture supports evaporation and heat dissipation, allowing rabbits to maintain a proper body temperature even in hot conditions. This is a key reason why healthy rabbits often have glistening, damp noses.

Enhancing Scenting Ability

Another reason rabbits have perpetually wet noses is to enhance their ability to detect scents. Rabbits have a remarkably strong sense of smell. In fact, their sense of smell is thought to be stronger than that of dogs. Rabbits use their sense of smell to monitor for predators, identify mates, locate food, mark territory, bond with their young, and gather all types of information from their environment. In order for rabbits to properly take in scents, the lining of their nostrils must be moist. When air passes over the moist inner lining, scent particles dissolve in the moisture. This allows the rabbits to then detect and interpret the smells. The wet nose surface similarly traps odor molecules. Rabbits are able to determine which direction a smell is coming from based on where the scent lands on their nose. Their brain then decodes what the scent is and makes decisions accordingly, like whether to approach something or flee from it. With a dry nose, rabbits would not be able to properly collect and assess all the scent cues around them. This could put them in danger or lead to other behavioral disruptions. So in short, the dampness on a rabbit's nose serves to trap odors and enhance their phenomenal sense of smell. It allows rabbits to gain tons of useful information about their surroundings using chemical signals in the air.

Wet Nose or Discharge?

While a moist nose is completely normal for rabbits, you do want to watch out for any excessive wetness or discharge coming from the nose. This is not typical and can signal an underlying health issue. Normal wetness on a rabbit's nose will look like evenly distributed moisture or glistening droplets across the surface of the nose. Sometimes the moisture collects at the top area of the nostrils as well. But you should not see thick discharge or excessive drippage coming specifically from the nostrils. This is a sign of excess nasal fluid production. Discharge is often opaque or discolored too, whereas normal nose moisture is clear. Other abnormal symptoms along with a wet nose include audible breathing or sneezing sounds, loss of appetite, lethargy, or eye discharge. If your rabbit's nose produces colored discharge, drips constantly, or has other accompanying symptoms, get them assessed by an exotic vet right away. This indicates a respiratory issue like an infection or irritation. Upper respiratory conditions can advance quickly in rabbits and become serious. So it is important to get treatment fast. Monitor your rabbit's nose daily so you recognize abnormal fluid or wetness if it develops. Distinguishing normal nose moisture from problematic discharge could save your rabbit's life.

Possible Conditions

There are some common upper respiratory conditions in rabbits that can cause a noticeably wet nose along with other symptoms like discharge or sneezing. Here is an overview of these conditions:


Snuffles is the common name for rabbit rhinitis, an inflammation in the nasal passages caused by a bacterial infection, usually Pasteurella. It is very contagious so often spreads through rabbit groups. The disease causes nasal discharge, sneezing, audible breathing, and wetness around the nostrils and face from the drip. Discharge may be thick and opaque, often white, tan, or yellowish in color. Severe snuffles can progress to pneumonia, facial abscesses, or eye infections. Treatment includes antibiotics, anti-inflammatories, and keeping the face clean. Supportive care and nursing is key during recovery. Snuffles must be treated aggressively at the first signs of infection.


Pneumonia refers to a lower respiratory infection in the lungs. Bacterial pneumonia is common in rabbits. Symptoms include wet nose, nasal discharge, low appetite, lethargy, rapid or labored breathing, and fever. The infection causes inflammation in the lungs and pus or fluid buildup. It is crucial to get veterinary treatment immediately as rabbits can decline rapidly with pneumonia. Broad spectrum antibiotics, nebulization, and supportive nursing care make up the typical treatment plan. Pneumonia in rabbits has a guarded prognosis but early intervention is key.


Myxomatosis is a fatal viral disease in rabbits that causes skin tumors and pneumonia. It is rare in pet rabbits if vaccinated, but still occurs in some wild populations. In addition to skin lesions, myxo causes respiratory disease. Rabbits develop severe congestion, discharge, and excess nose and eye moisture. The lungs fill with fluid and rabbits struggle for breath. Without treatment, most rabbits succumb to the pneumonia within 10-14 days. There is no cure but vaccinating rabbits prevents outbreaks. Prompt veterinary care, antibiotics, and nursing support can help prolong life in pet rabbits with myxomatosis. But the prognosis remains poor in infected rabbits.


In summary, it is completely normal for rabbits to have a damp, wet nose. This helps them cool off, pick up scents, and stay healthy. You should watch for any excessive nasal discharge though, as this indicates sickness. Respiratory infections are common in rabbits and lead to an overly wet nose along with other symptoms. Take your rabbit to the vet at the first sign of nasal drippage, difficulty breathing, eye discharge, or lethargy. Getting treatment early is crucial, as respiratory disease can advance rapidly in bunnies. With proper care and early intervention, many rabbits recover fully from respiratory infections. Monitor your rabbit's nose daily and keep up with vaccines to prevent the potentially serious health conditions that lead to an abnormal wet nose in rabbits.
