Man's best friends are smarter and more like humans than we ever thought. A
leading dog researcher and professor, Stanley Coren of the University of British Columbia, did a study. It showed that the
average dog has the mental abilities of a two-year-old child. These smart dogs can count to five and do simple math. They can also understand about 165 words, including signs, signals, and
gestures. Moreover, they can show basic emotions like happiness, anger, and fear.
Psychologists1 used tests that were designed for young children to see if dogs had certain mental abilities. The results show that the smartest dogs, which Coren calls super breeds2, can
recognize up to 250 words. Of course, not all dogs are created equal. Different breeds of dogs have different levels of
intelligence. At the top of the list is the Border collie. Poodles, German shepherds, golden retrievers, and Doberman pinschers make up the rest of the top five. The breed that scored the lowest is the Afghan hound. Although dogs are not Einstein, they should be treated and trained as smart and
sensitive individuals3 by their human owners.
