Definition of
Increased salivation in dogs, also known as hypersalivation or ptyalism, refers to an excessive production and secretion of saliva by the salivary glands, which usually leaves visible streaks of saliva around the dog’s mouth.

Grundlagen und mögliche Ursachen
Saliva plays an important role in a dog’s digestion and oral hygiene. It contains enzymes that help break down food and acts as a lubricant that makes swallowing easier. Normal saliva flow is therefore essential for healthy digestion and your dog’s well-being.
Excessive salivation can be caused by a wide range of factors. In some cases, the cause is harmless, such as excitement or waiting for a meal. In other cases, however, it can be a sign of an underlying health problem that requires veterinary treatment.
A common cause of excessive salivation is dental problems. Gum disease, tooth decay, or tooth abscesses can cause inflammatory conditions and pain, leading to increased saliva production. Foreign objects in the mouth, such as splinters or small stones, can also increase saliva production because the body is trying to flush the object out.
Another possible cause is irritation or injury to the oral mucosa, for example from chemical substances or toxic plants. Infections in the mouth area, such as fungal infections or bacterial infections, can also lead to hypersalivation.
Digestive tract disorders, such as nausea or gastrointestinal disease, can also be a cause of excessive salivation. In such cases, the increased saliva flow is often a precursor to vomiting. Neurological disorders that affect the control of the salivary glands can also cause hypersalivation.
Poisoning, especially from ingesting toxic substances, is a serious cause of excessive salivation. Some toxins irritate the mucous membranes or the central nervous system and lead to increased saliva production.
Typische Begleitsymptome
-
Restless behavior: Frequent shaking of the head or rubbing of the face may indicate discomfort or pain in the mouth area.
-
Bad breath: An unpleasant smell from the mouth can indicate dental problems or an infection.
-
Difficulty eating: Dogs with pain in the mouth area or nausea may be hesitant to eat or may not eat at all.
-
Vomiting: In cases of gastrointestinal problems or poisoning, vomiting may occur along with increased salivation.
-
Tooth pain: Dogs may frequently bring their paws to their mouths or chew more on a particular tooth.
-
Swollen or inflamed mucous membranes: Visible Inflammatory conditions in the mouth can indicate an infection or an injury.
-
Verändertes Verhalten: Allgemeine Unruhe, Rückzug oder Aggressivität können ebenfalls auf Schmerzen oder Unwohlsein hindeuten.
Wann zum Tierarzt?
A vet visit is urgently needed if excessive salivation is accompanied by other serious symptoms, such as vomiting, diarrhea, severe bad breath, or obvious pain. A sudden change in behavior or appetite should also be treated as a warning sign.
If you suspect that your dog has ingested a toxic substance, you should seek veterinary attention immediately, as some poisonings can be life-threatening and require immediate medical attention.
A veterinarian should also be consulted for persistent increased salivation that lasts longer than a few days to rule out underlying medical problems.
Symptomerkennung für den Tierhalter und tierärztliches diagnostisches Vorgehen
As a pet owner, you can easily recognize increased saliva production if you notice that your dog constantly has saliva dripping from their mouth or their face is often wet. Also watch for other Behavioral changes, such as restlessness or difficulty eating.
The vet will first take a thorough medical history, asking you about how long the excessive salivation has been going on, the circumstances around it, and any other symptoms. A thorough physical exam, especially of the mouth and throat, will be performed to rule out obvious causes such as dental problems or foreign objects.
Depending on what is suspected, further diagnostic tests may be needed, including blood tests, X-rays, or ultrasound to rule out infection, poisoning, or systemic disease. Saliva samples can also be examined to identify infectious pathogens.
In some cases, a neurological test may also be performed to detect possible disorders of the nervous system that could affect salivation.
Was kann der Tierhalter tun und professionelle Therapieoptionen
As a pet owner, you can take some measures to provide relief to your dog while waiting for the vet appointment. Make sure your dog has enough water available, as excessive salivation can lead to dehydration. Offer small, soft meals that are easier to chew and swallow, especially if dental problems are suspected.
Avoid giving your dog potentially irritating or chemical substances that could worsen the condition. Keep the mouth area clean and dry to prevent skin irritation from constant contact with saliva.
If you suspect your dog has ingested a toxic substance, try to identify the source of the poisoning and, if possible, bring information about the toxin with you to the vet. This can help with rapid diagnosis and treatment.
Monitor your dog’s condition closely and write down any changes or new symptoms that occur, so you can give the vet a comprehensive overview that may help with diagnosis.
Ausblick auf aktuelle Forschung
Current research on excessive salivation in dogs is looking at various aspects that could contribute to a better understanding of this symptom. One of the main lines of research focuses on the neurological and physiological mechanisms that regulate saliva flow. Scientists are investigating how the autonomic nervous system and certain neurotransmitter influence saliva flow in order to identify possible therapeutic approaches.
Another area of research examines the genetic predisposition to excessive salivation in certain dog breeds. Studies show that some breeds, due to their anatomical features such as skull shape or the structure of their salivary glands, are more prone to increased salivation. Researchers are trying to identify genetic markers that could explain this susceptibility, which in the long term could lead to more targeted breeding strategies.
In addition, studies are also looking at the role of environmental factors and diet in influencing saliva flow in dogs. Some studies suggest that certain nutrients or feed additives could regulate saliva flow. Stress and emotional factors are also being researched as possible triggers for excessive salivation. These studies could lead to non-drug approaches to controlling the symptom.
In addition, the role of infections and Inflammatory conditions in the mouth as triggers of increased salivation is being further investigated. The focus here is on how bacterial or viral pathogens impair salivary gland function. Advances in this area could lead to better diagnostic methods and treatment options.
Another interesting field of research is investigating possible links between excessive salivation and systemic diseases such as kidney disease or diabetes. Scientists are trying to find out to what extent increased salivation could be an early sign of such diseases, which would significantly improve diagnostics.
Finally, the effectiveness of various therapeutic approaches is also being studied, including drug treatments and alternative methods such as acupuncture or homeopathy. The goal is to find safe and effective ways to control saliva flow without significant side effects.
