Whether you can teach an old dog new tricks might be a moot point, but it seems some canines can rapidly learn new words, and do so through play.
While young children are known to quickly pick up the names of new objects, the skill appears to be rare in animals.
However, some studies have suggested certain dogs can learn what objects are called. Among them a border collie called Rico reportedly managed to learn the names of more than 200 items, while Chaser, also a border collie, learned the names of more than 1,000 objects.
