In the first study designed to show how much dogs 'prefer' their owners, scientists say they have also shown just how much dogs rely on seeing their owners faces in order to recognize them.
The researchers writing in the journal Animal Behaviour measured how much dogs prefer to gaze at and follow their owners, rather than a stranger and described how dogs had difficulty recognizing their human "best friend" when the person had their face covered.
