When a dog barks when there is no one in the room, at the door, or in any other place where there is no apparent reason for concern, the question arises: is he hallucinating or communicating with beings from other worlds?
Representatives of the American Kennel Club (AKC) attempted to find an explanation for this phenomenon.
They concluded that it was likely that such barking was not involuntary, but that people were simply unable to perceive visual, auditory or olfactory cues that were obvious to a dog.
For example, a dog may react to a distant car siren or other noise that a person next to him could not hear.
At night, when the level of surrounding noise decreases, the pet can better hear the howling and barking of other dogs.
Our four-legged friends are endowed not only with excellent hearing, but also with vision – in the dark they see much better than people.
When a dog becomes restless in an empty yard at night, it is likely that some object, such as a wild animal, a fallen leaf, or a stranger lurking in the bushes, has caught his attention.
However, dogs bark not only because of heightened senses: sometimes barking is caused by boredom or an attempt to attract the attention of their owner.
