Dogs are more expressive when someone is looking

first_imgYour pet may be deliberately making the cute puppy-dog eyes, say scientists who found that dogs produce more facial expressions when humans are looking at them. Scientists at University of Portsmouth in the UK are the first to find clear evidence dogs move their faces in direct response to human attention.Dogs do not respond with more facial expressions upon seeing tasty food, suggesting that they produce facial expressions to communicate and not just because they are excited.

The researchers studied 24 dogs of various breeds, aged one to 12. All were family pets. Each dog was tied by a lead a metre away from a person, and the dogs’ faces were filmed throughout a range of exchanges, from the person being oriented towards the dog, to being distracted and with her body turned away from the dog.”Domestic dogs have a unique history – they have lived alongside humans for 30,000 years and during that time selection pressures seem to have acted on dogs’ ability to communicate with us,” said Kaminski.”We knew domestic dogs paid attention to how attentive a human is – in a previous study we found, for example, that dogs stole food more often when the human’s eyes were closed or they had their back turned,” she said.”This study moves forward what we understand about dog cognition. We now know dogs make more facial expressions when the human is paying attention,” she added.last_img
