It can be seen that the owner of the dog had long stopped wanting to keep him, hence the actions.
The smart dog also sensed this and realized that its owner had betrayed it, thinking that it would never see its owner again, causing the dog to shed tears
The moment of the heartbroken dog shedding tears was captured by the staff at the dog shelter. Many days have passed, and the dog has been lying on the bed, with a face filled with its own sadness.
It breathes heavily, trembles all over, and its eyes are teary... all of these were reported by the staff here to be a result of the dog's owner bringing it into the shelter but never returning.
Perhaps the owner didn't know that dogs are animals that will always wait for their owner to come back, even if they are abandoned on the street.
The dog under the shelter received the care of everyone, but it seemed to only think about its owner, about why the owner brought it here but never returned.
Research has shown that most dogs are as intelligent as a 2-year-old child. They are animals that can understand their owner's facial expressions, which is why sometimes you might catch your own dog staring at you, as they are trying to figure out how you are feeling.
This will be reflected on their face, and in the story, the dog seems to understand that its owner truly betrayed it.
