1  It might understand more than you think. 
A dog named Rico recognizes the names of about 200 objects,say researchers in Germany.  2  Its word-1earning skills are as good as those of a parrot or chimpanzee.

In another experiment,the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. 4  .
The correct object was chosen in seven out of 10 tests.suggesting that the dog had worked out the answer by process of removing.A month 1ater,Rico remembered half of the new names,which is even more impressive.
