Lying
The most basic sound signal emitted by most dog breeds is barking.A dog barks primarily when its mood is a combination of dislike, fear and aggression. The more aggressive the dog is, the lower the barking sound; the more restrained and fearful the dog is, the higher the sound.
A dog that does not feel anxious will not bark unless the barking comes out as a reaction of excitement associated with a happy mood, or when the dog is in a state of mind that is characterised by barking. Such states are caused, for example, by hunting, which involves tracking a fast-moving bird or enveloping a captured prey. And, of course, a dog barks in situations where barking is of direct benefit to the animal: it is very easy for the animal to perceive that barking is a way of drawing attention to itself and, at the same time, of satisfying some need.
Barking
A dog that growls in a low voice is thus expressing an aggressive state, characterised by an almost vithe complete absence of a sense of dread. But a snarl does not necessarily mean that the animal will attack. On the contrary, growling is most common when a dog is really aggressive, but so-called social complexes prevent it from attacking and biting an opponent. In this case, the growling can be seen as a kind of expression of arrogance, the object of which is primarily an unfriendly person who is close by but who does not cause fear. If the dog does attack the fight, the growl then becomes a sound very similar to barking, although slightly different.
Squealing
A dog will start to whine in situations that are unpleasant for it. When an animal is actively trying to do something it finds pleasurable, but for some reason fails or is prevented from doing so, the dog will start to squeal or yelp and sometimes bark.
Growth
A wolf howls quite often and in a wide variety of situations, which is not the case with a dog. The main purpose of a wolf’s howl is as a signal aloneand for the members of the flock to get together when they hunt prey separately. the dog barks when it is sad, probably because it is alone. If you confine the animal to a room, it may begin to moan, but quite loudly and, to the annoyance of the neighbours, this may go on for hours. But it should be remembered that such growling does not mean that the owners are mistreating the dog. On the contrary, it is a sign of the dog’s strong attachment to the family. The habit of growling cannot be broken by punishment. A dog left alone in the house gradually gets used to the solitude and soon stops longing. However, when the dog is in an unusual place, the urge to howl may return, even if it no longer does so in its home.
Most dogs, such as Boxers, which have a kind of short muzzle, make sounds when breathing that are not part of the signals that a dog uses when its instincts kick in. Dogs that have not had to interact with Boxers may see this as a sign of hostility
