Dog owners know that dogs most often use body language to send an adequate message. In addition, they will often produce various sounds that serve to complement their body language.
Barking – Dogs use barking in a variety of situations. From guarding someone or something to attracting attention. Also, dogs use barking to expel excess energy due to great excitement or frustration.
When it is necessary to stay away – When a dog wants to keep a human, in most cases a stranger, at a distance he will produce a series of very deep barks. Often this kind of barking can go with physical attacks, ears placement close to the head, eyes wide open and mouth pulled back to show all the teeth.
Attracting attention – Small dogs are accustomed to a lot of cuddling and attention from the owner. If you notice that the owner and family ignore them, a series of very loud, intonation-high barks will begin. This barking is usually interrupted by short periods of silence during which they will observe whether they have managed to attract the attention of the desired person.
Snarling – Snarling dogs are used to intimidate opponents as well as to show a desire and readiness to fight.
Howling – Howling is a canine way of communicating with dogs that are far away from them. Dogs often howl when left alone, or in shelters and hospitals trying to communicate with members of their distant family or pack.
