What is normal nasal moisture?

A dog's nose is normally moist and cool. This moisture has several functions. On the one hand, it helps the dog to perceive odors better, because moist noses bind odor particles better. Secondly, nasal moisture helps to regulate body temperature. Dogs do not sweat like humans, but cool themselves by evaporating moisture through their nose and tongue.

Nasal moisture can fluctuate throughout the day. In the morning after sleeping, your dog's nose may be slightly drier, while during the day it becomes more moist again. The ambient temperature and humidity can also influence the dog's nasal moisture. A slightly moist or cool nose is therefore usually completely normal and no cause for concern.

Distinguishing between normal nasal moisture and unusual nasal discharge

A runny nose is different from a normal, slightly moist nose. Abnormal nasal discharge means that your dog's nose is continuously secreting fluid, often in large quantities that do not correspond to normal moisture. This discharge can be clear, cloudy, thick or even bloody and may come from one or both nostrils.

There are different types of nasal discharge that can indicate different problems:

Clear, watery dischargeIt may indicate an allergic reaction, irritation caused by dust or a mild infection. In some cases, a clear discharge is harmless and can occur with excitement or after physical exertion.
Thick, yellowish or greenish dischargeIt often indicates a bacterial or viral infection. Especially if the discharge smells unpleasant, you should consult a vet, as this can be a sign of a serious infection.
Bloody nasal dischargeBloody nasal discharge is an alarm sign. It can be caused by injuries, foreign bodies in the nose, nasal tumors or serious infections. In such cases, a vet should be consulted immediately.

When is a dripping nose a cause for concern?

A runny nose is not always a cause for concern, but there are certain signs you should look out for to detect serious problems early. If the nasal discharge persists for more than a few days or is accompanied by other symptoms such as fever, coughing, sneezing, loss of appetite or lethargy, you should have your dog examined by a vet.

A one-sided nasal discharge can also indicate a foreign body in the nasal cavity. Dogs that sniff a lot and are out and about in nature can easily catch blades of grass or small objects, which then lead to irritation and inflammation.

If your dog has difficulty breathing, sneezes heavily or shakes its head unusually often, you should also consult a vet. Such symptoms can indicate serious illnesses such as nasal tumors or chronic respiratory diseases, which must be diagnosed and treated at an early stage.

2. common causes of a runny nose in dogs

Dripping noses in dogs can be caused by a number of factors, ranging from harmless to serious. We give you a list of the most common causes of a dripping nose in dogs with explanations and advice on what to look out for.

Allergies

Pollen allergyDogs can have an allergic reaction to pollen from trees, grasses and flowers, especially in the spring and summer months. Symptoms include a runny nose, itching, sneezing and watery eyes.
House dust mitesAllergies to house dust mites are widespread in dogs. They can occur all year round and often lead to nasal discharge, skin irritation and breathing difficulties.
MoldsMolds can grow in damp environments and cause allergic reactions in some dogs. A runny nose, breathing difficulties and coughing are typical symptoms.
Feed allergiesSome dogs are allergic to certain ingredients in their food, such as grains, meat or additives. These allergies can manifest themselves through nasal discharge, digestive problems and skin rashes.

Infections

Bacterial infectionsA bacterial infection can be caused by small injuries in the nasal cavity or by the spread of bacteria from the mouth or throat. A common symptom is a thick, purulent nasal discharge.
Viral infections (e.g. kennel cough)Kennel cough is a highly contagious respiratory disease caused by various viruses. Dogs with kennel cough often show nasal discharge, a dry cough and general malaise.
Fungal infectionsFungi such as Aspergillus can infect the nasal cavity and lead to chronic nasal discharge, often with bloody or discolored nasal discharge. These infections are difficult to treat and often require intensive veterinary care.

Foreign body in the nose

Blades of grassEspecially in spring and summer, blades of grass can get into your dog's nose. They cause severe irritation, sneezing and nasal discharge, often on one side only.
Seeds and small objectsDogs that like to sniff outdoors can inhale small seeds or other objects that then get stuck in their nose. The result is a one-sided nasal discharge, often accompanied by sneezing and nosebleeds.
InsectsIn rare cases, insects can get into the dog's nose and get stuck there, causing irritation, severe sneezing and nasal discharge.

Environmental factors

Cold: In cold weather, your dog's nose may appear particularly moist as the body tries to protect the mucous membranes from drying out. This is usually harmless unless other symptoms occur.
Dry airIn dry, heated rooms, the nasal mucous membranes can dry out and produce more nasal secretions, which can be alleviated by using a humidifier.
Irritants in the environmentSmoke, perfume, household cleaners or other strong odors can irritate your dog's sensitive nasal mucous membranes and lead to temporary nasal discharge.

Dental problems

Tooth root inflammationTooth root inflammation can spread to the nasal cavity and lead to chronic nasal discharge, often accompanied by bad breath and inflammation of the gums.
PeriodontitisAdvanced periodontitis, an inflammation of the periodontium, can also cause nasal problems, as bacteria can enter the nasal cavity via the roots of the teeth.

Diseases of the respiratory tract

Chronic inflammation: Chronic inflammation of the nasal mucosa can be caused by various factors, including allergies, infections or autoimmune diseases. Symptoms include persistent runny nose, sneezing and occasional nosebleeds.
Nasal tumorsTumors in the nasal cavity or paranasal sinuses are rare, but can cause unilateral runny nose, nosebleeds and breathing difficulties. Early diagnosis is crucial for treatment.
Polyps: Benign growths in the nasal cavity or paranasal sinuses, known as polyps, can obstruct nasal flow and cause a runny nose. They often have to be surgically removed to alleviate the symptoms.

This list of possible causes shows that a dripping nose in dogs can have many different triggers. Pay attention to the accompanying symptoms and, if necessary, seek veterinary advice to determine the exact cause and initiate appropriate treatment.

4. treatment options for nasal discharge in dogs

The treatment of nasal discharge in dogs depends largely on the underlying cause. There are various approaches to alleviate the symptoms and improve the dog's health. This chapter presents the main treatment options, including drug therapies, home remedies and preventative measures.

Remedies and care

Steam inhalationSteam inhalation can help to moisten the nasal passages and loosen mucus. This can be particularly helpful for dry or blocked noses. You can do this at home by taking the dog into a bathroom with a hot shower running so that he can breathe in the steam. Make sure that the dog does not overheat and that fresh water is always available.
HumidifierA humidifier can help to increase the humidity in your home, especially in the winter months when the heating dries out the air. More humid air can help to moisten your dog's nasal mucous membranes and reduce nasal discharge.
Nose careRegular cleaning of the nostrils with a soft, damp cloth can help to remove dried nasal discharge and prevent irritation. For dogs with heavy discharge, a mild balm specially formulated for dogs can be applied to the nasal skin to keep it supple and prevent cracking.
Strengthen nutrition and the immune systemA balanced diet rich in vitamins and minerals can strengthen your dog's immune system and help him to better fight off infections. Supplements such as omega-3 fatty acids can have an anti-inflammatory effect and promote general well-being.

Drug treatment

AntibioticsIf the nasal discharge is caused by a bacterial infection, the vet will usually prescribe antibiotics. These drugs help to kill the bacteria and fight the infection. It is important that the treatment is carried out completely, even if the symptoms have already subsided, in order to avoid relapses.
AntihistaminesAntihistamines can be prescribed for allergic reactions to relieve allergic symptoms. These medications reduce the production of histamine, which is released during allergic reactions, and thus help to reduce nasal discharge and sneezing.
Corticosteroids: Corticosteroids can be used for severe allergies or inflammation. These medications have an anti-inflammatory effect and can help to relieve symptoms quickly. However, they should only be used in the short term, as they can have side effects if used over a longer period of time.
AntifungalsFungal infections in the nasal cavity, for example caused by Aspergillus, are treated with antimycotics. These medications often have to be taken over a longer period of time, as fungal infections can be persistent.
PainkillersIf the nasal discharge is associated with pain, such as dental problems or nasal tumors, pain medication can be used to improve the dog's comfort while the underlying cause is treated.

Medication should only ever be administered after careful diagnosis and consultation with the vet.

Preventive measures

Allergen avoidanceIf your dog suffers from allergies, it is important to avoid the triggers as much as possible. This includes regular cleaning of floors and upholstered furniture to remove pollen or dust mites. Bathing your dog after a walk outside can also help to remove pollen from its coat.
Regular dental hygieneAs dental problems can be a cause of nasal discharge, good dental hygiene is essential. Brushing your teeth regularly and checking for signs of gum disease can help prevent tooth root infections that can spread to the nasal cavities.
Protection from environmental stimuliAvoid exposing your dog to strong environmental stimuli such as smoke, strong chemicals or perfumes. If you live in a highly polluted environment, provide fresh air where possible or go for walks in less polluted areas.
Regular veterinary examinationsRoutine examinations at the vet can help to detect problems early before they get worse. For example, during a dental or respiratory examination, the vet may detect signs of problems that would otherwise have gone unnoticed.

The treatment of nasal discharge in dogs is varied and depends heavily on the cause. While medication is often required for infections and allergies, home remedies and preventative measures can help to alleviate symptoms and improve the dog's general well-being. It is important to determine the exact cause of the nasal discharge in order to initiate the right treatment. Through a combination of targeted medical treatment, home care and prevention, you can support your dog's health in the long term and help him to recover quickly.
