From Discovery News:
Language skills once thought exclusively human are also within the reach of dogs, say German researchers studying a nine-year-old border collie that has a 200-word vocabulary. …
In a game where Rico is told to fetch an unfamiliar object with a name he hasn’t heard before, Rico runs into a room where the new object is on the floor among several familiar objects, of which he already knows the names. Rico reliably figures out that the new word must go with the new object in a single try. Then, after a month of not seeing the new object or hearing the new word, he remembers them.
What’s scary is that he’s 9, which means 63 in human terms, right? I’m younger than that and I can go into a room and forget what I went into it for.
