“When dogs make the movement, it seems to elicit a strong desire in humans to look after them,” says the study, co-authored by Dr Juliane Kaminski at the University of Portsmouth.
The findings, from UK and US researchers in anatomy and comparative psychology, show that the facial change has developed over thousands of years of dogs living alongside humans.
