Numerous triggers can make the dog drool. For one, the breed plays a role. With dogs like mastiffs, St. bernards, newfoundlands or boxers, strong saliva is not uncommon. However, if your four-legged friend is not one of them and nevertheless suddenly salivates heavily, the exact cause of this must be researched.
Dog salivates a lot: In search of the cause
In order to clarify the reason behind sudden extreme drooling, you should first carefully observe your four-legged friend: does he show any other symptoms that suggest an illness? For example, is he tired or listless? Does he keep shaking his head? Does he refuse the feed?
You can then check the dog's mouth for visible changes. If you are unable to determine and correct the cause of the extreme salivation yourself, going to the vet is always a good idea.
For a first orientation, you will find an overview of the most common causes of an enormous flow of saliva in dogs.
1. Foreign body in the mouth
Often, the reason for excessive salivation is a foreign body that has got stuck between the dog's teeth or gums. Looking into the mouth of your furry partner, you might discover a piece of bone, wood, or a fish bone, for example.
If you are unable to remove them without causing pain to the dog, you cannot avoid visiting the vet.
2. Gum infections and dental diseases
If the gums are red or swollen or if you discover a broken or loose tooth, this can also cause your dog to drool.

3. Too extreme heat
Many dogs are sensitive to heat. Dogs with a short snout like the pug, the Boston Terrier or the bulldog, in particular, therefore start to salivate quickly in high heat.
It is important to always have water ready for the four-legged friends and not to expose them to the blazing sun for too long, because in the worst case, drooling can only be a first warning signal for dehydration and subsequently for a heat stroke.
4. Anxiety and stress
Anxious dogs also tend to salivate. Numerous dogs drool while driving. This is mostly caused by nervousness or travel sickness.
For this reason, it is advisable to slowly get the dog used to driving in the car. For example, just put it in the car for the first time without starting. This will ease his excitement.
Also meeting other fellow species, for example when walking the dog, can cause stress and thus excessive saliva in your fur nose.
If a dog is drooling and whimpering at the same time or does not want to move, this is often his way of telling you that he is in pain. These can have a variety of reasons that a veterinarian can usually determine most quickly.
The fact that a dog is drooling suddenly can also indicate poisoning. If the four-legged friend has ingested poisonous plants or other toxic substances or has become a victim of a poisonous bait, excessive salivation can occur as a symptom. In most cases, poisoning is accompanied by other side effects such as vomiting, tremors, convulsions and loss of consciousness.
If your dog is drooling extremely and you suspect poisoning behind it, quick action is required. The rule is: go to the vet!
7. Other possible causes
If you were able to completely rule out the previous reasons, the salivation can also have deeper causes. Liver disease and stomach problems as well as an abscess or tumor cannot be excluded. If, despite your best efforts, the strong salivation continues over a longer period of time, extensive examinations by the veterinarian are necessary.
