Dogs Learn Words by Eavesdropping, Study Finds

Research published in the journal Science indicates that certain dogs possess the remarkable ability to acquire new vocabulary by merely eavesdropping on human conversations, a skill previously observed in young children. A study involving ten "gifted word learner" dogs demonstrated that they could learn the names of two new toys after brief exposure, including instances where they were not directly addressed or in sight.

In controlled experiments, owners introduced new toys and their names. Astonishingly, seven of the ten dogs could correctly identify the toys after only eight minutes of direct interaction. The study further revealed that the dogs could learn these new labels even when they only overheard their owners discussing the toys indirectly, mimicking the passive word acquisition seen in 18-month-old children.

These findings suggest that the cognitive and social mechanisms enabling learning through overhearing may predate human language itself, potentially explaining why dogs, selected for their ability to understand human communication during domestication, exhibit similar learning patterns. While this capacity is not general to all dogs, it showcases the profound depth of understanding some canines possess regarding human interactions.
