Dogs are smarter than toddlers, IQ tests show

The canine IQ test results are in: Even the average dog has the mental abilities of a 2-year-old child.

The finding is based on a language development test, revealing average dogs can learn 165 words (similar to a 2-year-old child), including signals and gestures, and dogs in the top 20 percent in intelligence can learn 250 words.

And the smartest?

Border collies, poodles, and German shepherds, in that order, says Stanley Coren, a canine expert and professor emeritus at the University of British Columbia. Those breeds have been created recently compared with other dog breeds and may be smarter in part because we've trained and bred them to be so, Coren said. The dogs at the top of the pack are on par with a 2.5-year-old.

Better at math and socializing
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.

To find out which dogs had the top school smarts, Coren collected data from more than 200 dog obedience judges from the United States and Canada.

He found the top dogs, in order of their doggy IQ are:

1. Border collies
2. Poodles
3. German shepherds
4. Golden retrievers
5. Dobermans
6. Shetland sheepdogs
7. Labrador retrievers

At the bottom of the intelligence barrel, Coren would include many of the hounds, such as the bassett hound and the Afghan hound, along with the bulldog, beagle and basenji (a hunting dog).

"It's important to note that these breeds which don't do as well tend to be considerably older breeds," he said. "They were developed when the task of a hound was to find something by smell or sight." These dogs might fare better on tests of so-called instinctive intelligence, which measure how well dogs do what they are bred to do.

"The dogs that are the brightest dogs in terms of school learning ability tend to be the dogs that are much more recently developed," Coren said. He added that there's a "high probability that we've been breeding dogs so they're more responsive to human beings and human signals." So the most recently bred dogs would be more human-friendly and rank higher on school smarts.

Many of these smarty-pants are also the most popular pets. "We like dogs that understand us," Coren said.

We also love the beagle, which made it to the top 10 list of most popular dog breeds in 2008 by the American Kennel Club. That's because they are so sweet and sociable, Coren said. "Sometimes people love the dumb blonde," Coren said.

And sometimes the dim-wits make better pets. While a smart dog will figure out everything you want it to know, your super pet will also learn everything it can get away with, Coren warns.
