As many a dog owner will prove, our furry friends are listening. Now, for the doubters, there is scientific proof that they understand much of what they hear. A border collie called Rico can fetch at least 200 objects by name， researchers in Germany say. The dog also appears to learn words for new objects as easily as a 3-year-old child would. Its word-learning skill is as good as that of a parrot or chimpanzee.
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them randomly into 20 sets of 10 objects each. The dog waited with one of his owners in one room, while an experimenter put a set of 10 objects into another room. Then, the owner told the dog to fetch one of the items. The dog had to go to the other room and bring the object back.
