There are obvious benefits to having dogs rather than children. Your dog will never slam a door in your face or tell you they hate you. They can be potty trained in eight weeks. They don’t need clothes, a car, or a college education.
In recent years, several discoveries about dogs make kids even less unique. It turns out that dogs are startlingly similar to human infants in several key areas, one of which is in the social domain.

By paying attention to the reactions and gestures of other people, as well as to what other people are paying attention to, infants are beginning to read other people’s intentions. This ability provides a foundation for all forms of culture and communication.
Every dog owner has helped a dog find a lost ball or stick by pointing in the right direction. It’s easy to take for granted the way dogs effortlessly interpret this simple gesture, but this ability is remarkable. Not only do dogs understand the meaning behind the point in a similar way to human infants, they are using the social information of a completely different species.
