When Do Dogs Drool for Unnatural Reasons?


A healthy dog releases about 1 liter of saliva per day. It is to facilitate chewing and passage of food through the esophagus. It also disinfects the gums and teeth. Normally it can only drip from the tongue, if the dog is breathing heavily, but it should not drip from lips and chin.

The exception is such breeds as: Basset hound, Boxer, Mastiff. So what does it mean if a dog is drooling a lot, regardless of the meals and even at rest?


If the mucous membrane of the mouth was injured, then a strong salivation is possible. Of cause, not every wound is accompanied by excessive salivation, but still it is necessary to look closely at the teeth and gums of your pet. It is also possible that some sharp object is stuck in gums. This is painful and irritating for the dog. What is more, if you dog is drooling a lot and shaking headdo not treat the wound in time, a purulent abscess may develop. Despite the fact that saliva has weak disinfecting action, it will not cope with such problem itself.

A blow to the jaw and knocked-out tooth also lead to the fact that the dog is drooling and shaking head. Owners often notice this immediately. When the dog cannot clench the jaw or any of the teeth is sticking out, the cause most likely is an injury.

In such cases, the dog is drooling a lot from one side. You cannot improve fractures and dislocations of the jaw independently. With a knocked-out tooth, you have to visit a vet, because it is actually an open and painful wound prone to bacterial infection.

Dental Diseases

With many ailments of the dental sphere there are inflammations, which cause increased release of saliva. This is the way the body tries to cope with the disease. These diseases include:

  1. dog is drooling a lot and shakingstomatitis is an inflammatory process of different etiology (bacterial, traumatic, carious). Gums begin to bleed and blush;
  2. periodontal disease is softening and severe inflammation of the gums, up to the loss of teeth (especially typical for older dogs). In advanced cases, the gums can rot and bleed;
  3. bite pathology;
  4. inflammation of the salivary glands.

The bite problems should be mentioned separately, because some people find affectionate the strange angles fangs protruding from under the lips. However, only in some dogs it does not affect the quality of life. Congenital malocclusion can gradually degrade even more and the teeth will not just stick out – they will break through the lips or gums. In addition, such an animal cannot eat properly.

When inflammation of the salivary glands, a dog is drooling a lot and shaking, because it is often accompanied by an increase in body temperature. There will be no appetite either. If these symptoms are absent, then the reason is different and there is no need to panic. For example, in puppies abundant saliva release is quite a natural thing during growth. In older dogs it is due to the lack of careful dental care.

Disorders of the Digestive System

Excessive salivation may be due to motion sickness. Not all dogs tolerate long trips in the car, especially in hot weather. Sometimes the animal does not vomit at once. The poor pet may have difficulties in breathing and saliva dog is drooling a lot causesmay be dripping from the tongue abundantly. In such a situation it is necessary to stop and give your pet some rest on the fresh air. If there is no such an opportunity, you should prepare a package for vomiting with foam, as it will almost certainly begin after some time.

When poisoning or foreign objects in the esophagus, you can also observe a large amount of saliva secreted. This is provoked by irritation of the mucosa and attempts to “wash out” what causes it. It also stimulates the gag reflex-a natural way to cleanse the stomach of toxic substances.

So if the dog is drooling and vomiting, it is likely that it has eaten something spoiled. You should try to figure out what it was, give medicines and watch the pet for a couple of hours. If symptoms do not pass or worsen, you have to go to the vet.

Pathology of the Nervous System

There are some diseases that are characterized by permanent or temporary paralysis of a number of muscles, in this case – the jaw muscles. This symptom often indicates rabies. However, this is not the only sign and you should not immediately sound the alarm. If you notice seizures, it is likely epilepsy, which is very dangerous. Each attack gives a huge load on the heart and can be the last one. Strong salivation also occurs in botulism. Do not try to treat the dog on your own!

A large amount of saliva may indicate a disease only in case there are other symptoms. If there is a single manifestation, this could be quickly passed mucosal irritation or some smell that caused such a reaction. Animals do not like any harsh flavors or odors, so they often try to wash them away with saliva.
