Why do dogs drool?

Increased drooling, in some cases, is a physiological feature of certain breeds. But sometimes in dogs that are not prone to this phenomenon, suddenly begins to flow copiously saliva. In what cases does this process take place within the framework of the norm, and when is it necessary to sound the alarm? All possible causes of this phenomenon should be considered. So why does a dog drool from its mouth?


Rocks prone to drooling

Everyone knows that some breeds from nature, more precisely from breeding activities, were rewarded with such a feature - drooling. This property is manifested in quadrupeds with muzzles of impressive size, in the presence of shortened jaws or fleshy, friable broths.

Why do dogs drool?

In pets with such anatomy, copious salivation occurs for any, even minor, reason. This can occur from the heat, during cooling, with any emotional excitement - joy, anxiety, surprise. Even when the dog is asleep, saliva can flow from him.

In the list of "slobbering" breeds you can find the Bloodhound , Shar-Pei, Newfoundland, St. Bernard , Boxer , almost all varieties of bulldogs and mastiffs, Caucasian Shepherd Dogs .

Modern breeders are puzzled by the decline of this not very pleasant quality, and the modern representatives of breeds have slightly reduced saliva. This is due to the fact that overly loose representatives of the breed, if possible, are not used in breeding processes, and the constant flow of saliva is considered a significant disadvantage.

This must be considered when choosing a puppy of a breed prone to drooling. It is necessary to observe parents how this quality is expressed at them. If dogs flood everything around, then most likely their child will be the same.

Are you lucky and the puppy gives off a little salivary fluid? It was lucky ... And if not, then there is only one way out; constantly wipe the face and everything around, since there is no treatment for this anatomical feature.

If with certain breeds everything is clear, then in other dogs this phenomenon can be attributed to an alarming sign. It signals that a pet had a disturbance in the activity of the salivary glands, which are responsible for the secretion of this physiological fluid.

A medium-sized animal produces about a liter of saliva per day; if you increase this reading, you should be concerned about the condition of your pet. There is an impressive list of reasons why the dog increases salivation (as this phenomenon is called in medicine), and they are far from always harmless. Vet consultation and emergency treatment is often required. Therefore, it is important to pay attention to this process.

Oral cavity pathologies

Dogs are prone to diseases of the teeth and gums, and they are often accompanied by increased salivation. Dogs may cause caries, stomatitis , tartar (in some breeds, the mouth is a weak point) - these ailments are often accompanied by painful sensations, inflammatory processes, which the pet's immunity tries to eliminate in a not very effective way - by active salivary fluid secretion.

Watch your dog eat

In this case, it is possible to get rid of saliva only by eliminating the root cause, that is, curing the disease. To identify the problem, you should look at the behavior of the dog, with diseases of the oral cavity, it behaves as follows:

  • Shows unusual care during the meal;
  • eats slower than usual;
  • head constantly lowered to the floor;
  • trying to eliminate itching in the jaw area;
  • if you touch, it can scream, snap or just trying to retire, hide.

Similar signs are observed when a foreign body enters the mouth, therefore, if you detect such behavior, you should carefully examine the mouth. Often, the owners discover an alien object - a bone, a piece of a branch or another.

If blood is present in the salivary fluid, then perhaps the dog has injured the tissues of the sky, gums, or tongue. If a wound was discovered during the inspection, it should be treated with disinfectant agents. If there is suppuration in the wound, it has become inflamed or has become larger, then the pet should be shown to the veterinarian.

Diseases and injuries of auricles

Around the ears are large glands, which are called parotid. In their function and includes the production of salivary fluid. Naturally, ear injuries, diseases (caused by pathogenic fungi, bacteria, etc.), tumor formation, otitis, affect their work, causing increased salivation.

You can save your pet from salivation only by curing its ears from the disease. Ears will be healthy - parotid gland activity will return to normal.

Virus infections

Viral infections have a number of signs, in addition to enhanced salivation, which are easy to detect:

  • the dog eats little or refuses food altogether;
  • the animal becomes lethargic;
  • body temperature rises;
  • the dog constantly feels thirsty.

Even 1-2 symptoms should disturb the owner and become the reason for seeking medical help. You should not independently engage in the diagnosis and treatment of infection caused by a virus, since it is impossible to rid the dog of such diseases without diagnosis and professional knowledge. In addition, it should be remembered that some viruses can not only become a threat to the life of an animal, but also have the ability to be transmitted to humans.

Chronic illnesses

Increased salivation can signal the transition of any disease from acute to chronic. The list of such ailments is quite extensive, but the following are among the most common:

  • gastrointestinal diseases (malignant and benign tumors, inflammation of the stomach, duodenum, including ulcers);
  • violations of the internal organs (liver, spleen, gallbladder).

In fact, chronic disease of any system and organ can provoke excessive salivation. In females, such a phenomenon often occurs in violation of the hormonal background, diseases of the reproductive organs, during gestation of offspring.


Severe drooling occurs with any degree of severity of intoxication. Poisoning in a dog can be caused by ordinary, but difficult for the digestive tract food - sweets, fatty meats, fruits. Often pets get poisoned due to contact with toxic substances - poisons, fertilizers, household chemicals. Also, the dog may be poisoned by swallowing any stale or rotten product during walking.

The dog got poisoned

Penetrating into the gastrointestinal tract, a toxic substance irritates it, causing biliary outflow and sometimes outflow of gastric juice. Such exposure causes increased salivation, vomiting, and loose stools. Sometimes intoxication is accompanied by intense heat, thirst, possibly blanching of mucous tissues.

To quickly help your pet, you should use the same means as in the case of poisoning people - give the drug-absorbent - Enterosgel, activated carbon, Polysorb, white coal, etc. If the signs do not go away, you need to seek the help of professionals.


Dogs, like people, can be hard going through a stressful situation. Abundant flow of saliva can be interrelated with the psychological state of the pet. Among the common causes of stress in dogs are the following:

  • change of owner;
  • relocation;
  • new pet in the house;
  • conflict with another animal;
  • appearance of a baby in the house;
  • rough treatment by the owner.

Any of these factors can trigger a strong flow of saliva. To rid the dog of this phenomenon, first of all, it is necessary to normalize the state of its nervous system. It should be more attentive to the pet, walk more often and longer, drive to new, unusual places, be patient and affectionate.

If there are more pronounced signs of disorder, it is best to contact a veterinarian who may prescribe medication or herbal remedies with a sedative effect.
