Nowadays, pet dogs live in a human world that is not the same as their primitive life.The sound of footsteps outside the door, the ringing of the telephone, the sound of opening and closing the door, the sound of the elevator, etc. are not only new to puppies, but also tend to cause them emotional tension.
When owners speak to their puppies in a calm and soothing tone of voice, oxytocin is secreted in the puppy's body, which will make the anxious ones feel calm and happy as well as secure, which benefits their overall physical and mental health. 
Of course communication with dogs is still an emotional interaction, during the conversation we can use our hands to gently stroke their heads and backs, this physical contact helps to deepen the emotions between us and our dogs. And dogs are very good listeners, as a loyal companion, it will patiently listen to what you share, will not interrupt you, and will not judge your language. This kind of unconditional listening and companionship can bring great comfort and support, and is also very good for our physical and mental health.
