Why Do Dogs Bark at People?
Barking is one of the ways dogs speak to us.Dogs bark because it is one of the ways they communicate. A dog may bark to warn that someone is coming, to guard its territory, because it is lonely, bored or wants attention, because it is frightened, or because it is ill or in pain. A tail held high with ears up and forward looks threatening, while ears pulled back and a low tail suggest fear.
Barking is a kind of talking
Barking is one of the ways dogs talk. The animal services page for Augusta, Georgia, explains that a bark can mean different things depending on the situation. Sometimes it is useful, like a warning that someone is coming near the property. Other times a dog barks so much that it becomes a problem for the people it lives with. The first step, the page says, is to work out why the dog is barking.
The same dog can have a different reason in a different situation.
Lonely, bored or seeking attention
Loneliness, boredom and wanting attention are common reasons. The same page notes that barking may increase when a dog is left alone for long stretches, has few companions or toys, or is a puppy or adolescent under three years old with energy to burn. A dog that barks until someone comes has learned that barking brings company, even if the person only comes to say quiet. If a dog barks only when you leave, it may be separation anxiety; clues include getting restless as you get ready to go and following you from room to room.
Guarding territory and feeling afraid
Dogs also bark to guard their territory or because they are afraid. The Augusta page describes a dog barking at the mail carrier, at children walking to school or at a neighbouring dog: if its tail is held high and its ears are up and forward, the posture looks threatening. On the other hand, ears pulled back and a low tail during thunder, fireworks or construction noise suggest fear. Bellevue, Washington, suggests changing your training depending on whether the dog is barking to alert, to demand, from fear or from boredom.
When something hurts, and local rules
Sometimes a dog that barks and barks is unwell. The Augusta page suggests a thorough check-up at the vet, because illness, pain or parasites can lead to excessive barking.
