I just saw this. Well I always believed dogs to be intelligent creatures. Certainly more so than cats. Curiously the study also found that dogs were smarter than 3-4 year old toddlers at basic arithmetic:
While dogs ranked with the 2-year-olds in language, they would trump a 3- or 4-year-old in basic arithmetic, Coren found. In terms of social smarts, our drooling furballs fare even better.
“The social life of dogs is much more complex, much more like human teenagers at that stage, interested in who is moving up in the pack and who is sleeping with who and that sort of thing,” Coren told LiveScience.
