Like Toddler, like Doggie
Updated: Feb 1, 2020
A dog’s ability to express emotions is same as that of a two and a half year old human child.
It is capable of feeling and communicating emotions such as excitement & joy, jealousy, suspicion, shyness, distress & sorrow, disgust, anger, fear, contentment, love and affection.
Since time immemorial dogs have been amiably living around human species and are the oldest domesticated animal. In the course of co-existing and evolving together dogs have come to understand humans and communicate with them effectively by picking up cues via body language, familiarity of voices and smells.
