Dogs bark because they are lonely

If you rarely interact with dogs, your dogs may bark because they are lonely. Sometimes, your dog will feel unsafe and bark if you don't hold it.

The training method is: you should usually spend more time with your dog, and leave it with its favorite toys, plenty of food and water when you go out, to prevent it from barking because its basic needs cannot be met. You should also interact with your dog more often to make your dog feel safe. You should usually spend more time with your dog, and prepare his beloved toys, sufficient food and water for him when you go out to prevent him from barking because his basic needs cannot be met.

Dogs will bark to defend their territory

Some dogs bark purely as a demonstration to protect their territory. In the process, They create a "demonstration/response" cycle.
For example: a dog barks at a person who is delivering a courier to the owner's house as a "demonstration". The courier's departure is viewed by the dog as a "demonstration" and a "response" - an outsider "showing weakness" leave". This "feel-good" dog will growl at anyone who enters its territory.
To solve this problem, you have to sternly say "No!" or "Quiet" to the dog when it starts barking, and praise the dog when it stops barking. Still emphasizing that sentence, the prerequisite for giving the "quiet" command is that it "is" barking.

Dogs bark due to separation anxiety

Dogs left alone at home may be more or less anxious, and some will express it through barking The inner fear of the dark room and the resentment towards the cruel owner. You can avoid this by training your puppy to be calm and alone. This training also works for older dogs, but it takes more time and patience.
Put the puppy in a room alone, say "Quiet" to it, then leave the room and close the door. If the dog barks right away, turn back, repeat "quiet," and then leave.
If the dog can be quiet for a period of time, praise it well. Slowly extend the time it is left alone, and let the dog understand that as long as it is quiet, it will be rewarded.
