Common Reasons For Dog Barking And Drooling

Dog barking and drooling can be caused by a combination of factors, and the specific cause can vary from one dog to another, therefore it is important to consider all possible causes in order to determine the most appropriate course of action.

The common causes of dog barking and drooling include:

Excitement or arousal

Dogs may bark and drool as a way to express their excitement or when they are stimulated by something, such as a new toy or a treat.

This is a normal behavior and is not usually cause for concern.

When excited, a dog may produce more saliva due to an increase in activity in the salivary glands and they may also bark more due to an increase in energy and arousal. 

These behaviors are typically temporary and subside once the excitement has passed.

Medical conditions

In some cases, dog barking and drooling may be a symptom of an underlying medical condition.

This includes conditions such as a dental problem, poisoning, gastrointestinal issue or a neurological condition which can lead to increased salivation and  cause a  dog to be more vocal.

Separation anxiety

Some dogs may bark and drool when they are left alone or separated from their owners, which can be a sign of separation anxiety. 

Other behaviors due to separation anxiety include pacing, crying or whining, urinating, defecating, and destructive behavior such as digging or chewing items.

Fear or stress

Dogs may bark and drool when they are fearful or stressed, due to loud noise such as noise from a thunderstorm or fireworks display. This is a natural response to a perceived threat.

During times of fear or stress, a dog may produce more saliva and they may also bark more due to an increase in arousal and anxiety.

These behaviors are also usually accompanied by other signs of fear or stress, such as panting, whining, trembling, or hiding.


Barking and drooling is an inherited trait that are present in certain dog breeds. Some dogs naturally drool more than others and when they bark, these two behaviors are present.

This barking and drooling for these breeds is natural and is not usually a cause for concern.
