One of the main reasons that dogs love and care for their owner is that they are extremely loyal. These clever animals care for their owners as long as they can.
Tianlang is a clever dog who cares for his owner even after falling asleep. First, he takes the phone from her hand and then puts it on the bed but still within reach.
After that, he pulls the blanket and covers her. He even turns the night light on and turns the main light off.
So the owner knows that even when she is asleep her dog is next to her guarding and caring.
