Why do humans like dogs?


assistant
Humans like dogs because they have evolved together over at least 18,000 years. During this time, dogs have learned to identify and understand complex human expressions, including facial cues and vocal language and pitch. In turn, dog physiology and cognitive development has evolved the facial muscle sets and vocalizations and cognitive communication skills which enable them to communicate their states of emotional and physical being.
