Great Danes drool moderately because of their natural lip structure and loose lips that let out accumulated saliva from the mouth.
Drooling is normal however excessive drooling can be a cause for concern and can be a sign of a serious problem.
So why is your Great Dane drooling so much?
Let’s look at the common reasons why Great Dane drooling occurs, the potential complications, and when to seek help.
Why Is My Great Dane Drooling so Much?
Excessive Great Dane drooling can occur because of illness, excitement, esophageal obstruction, oral or dental disease, upper respiratory tract infection, heatstroke, poisoning, stress, nausea, motion sickness, allergies, and certain medications.
Possible Causes of Great Dane Drooling
Some conditions and diseases cause a Great Dane to drool more than usual. Conditions such as seizures, liver disease or kidney disease, rabies, infections, and bloat cause drooling.
If your Great Dane is excessively drooling, an underlying disease or condition is likely to be the cause.
Drooling is normal in all dogs due to excitement. Excessive saliva production is triggered due to this emotion and your dog can’t help but drool.
Excitement can come from anything that makes your dog very happy such as seeing you after a long day of separation, car rides, or anticipation for food during meal times.
Esophageal obstruction means a foreign material or object lodged in your Great Dane’s throat or mouth.
The obstruction causes difficulty in swallowing saliva which accumulates in the mouth, resulting in excessive drooling.
The obstruction can occur when a Great Dane swallows things that they should not eat including broken toys, rocks, sticks, or bones.
Obstructions in the mouth and throat can also be due to the growth of tumors.
Oral and dental disease
Gum inflammation, tooth decay, tartar build-up, and oral tumors cause excessive drooling. Gingivitis and periodontal disease cause gum flare-ups
In addition to this, if your Great Dane has a mouth injury, cuts, chipped teeth, or bruises, these can also cause drooling.
Upper respiratory tract infection
Infection of the upper respiratory tract, which is an infection of the nose, throat, and sinus, can cause drooling.
In hot weather, dogs pant to create a cooling effect and cool off. During this process, a dog can overheat and suffer from heatstroke and excessive drooling also occurs.
When your dog has been in the sun for too long and lacks access to drinking water, they are likely to suffer from heatstroke.
Ingestion of poisons also leads to drooling which is one of the many symptoms of poisoning.
A Great Dane may accidentally ingest poisonous substances such as plants, frogs, spiders, or household products.
Stress and Anxiety
Drooling is also a symptom of stress and anxiety. When your Great Dane feels uncomfortable in a stressful situation, this causes stress which triggers excessive drooling.
Stress can come from being in a new environment, meeting new people or animals, or loud noises.
Nausea can result from eating items that they should not such as garbage, poop, or non-edible objects.
Dogs will always explore their environment with their mouth and nose and this is bound to happen.
Great Dane drooling will occur because of nausea which is accompanied by stomach discomfort.
Therefore if this happens, your dog may have ingested something it should not have eaten.
Nausea can also be a result of motion sickness which results in drooling.
Great Danes experience motion sickness when in a moving car. Motion sickness causes anxiety and nausea which causes your dog to drool excessively.
Other symptoms of motion sickness include licking or smacking of lips, constant yawning, whining, vomiting, inactivity, and uneasiness.
Allergic reactions cause drooling as an allergic response. Common symptoms of allergic reactions include itchy skin, sneezing, wheezing, coughing, or a runny nose or eyes.
Certain medications can also cause the production of excess saliva. If your Great Dane is under medication and drooling occurs, this is likely to be the side effect of the medication.
Moderate drooling in a Great Dane is normal however it can also be a symptom of life-threatening conditions or diseases.
Therefore the major complication of Great Dane drooling is a fatal outcome, that is, death if the underlying cause is untreated.
Conditions such as kidney disease, liver disease, seizures, infections, bloat, and rabies are fatal.
When to Seek Help for Great Dane Drooling
Some conditions that cause Great Dane drooling may not need medical attention such as excitement, drooling after drinking water, or due to medication.
These are normal typical Great Dane drooling and only require a drool rag to enable you to wipe their drool in these cases.
Great Dane drooling can also be caused by underlying health problems therefore it is also important to seek medical attention to help determine the underlying cause and rule out any illness.
Seek medical help if your Great Dane:
- Shows other symptoms of sickness such as weakness, fever, vomiting
- Displays behavioral changes such as not eating, or disinterest in activities
