Dogs are largely thought to be one of the most intelligent species of animals, right up there with chimpanzees, elephants and dolphins.
But when you get down to the nitty-gritty of it and start observing dogs based on their behavior, responsiveness and trainability, some pooches move to the head of the class.
If you're looking for the best and the brightest (and cutest, in our opinion), these 10 breeds rank among the smartest dogs in the world.
10. Australian cattle dog
Yes, the Australian cattle dog from Down Under.
A working dog that is traditionally occupied with controlling and herding cattle, its qualities are exceptional intelligence, alertness, resourcefulness and a fiercely protective loyalty over its property and people.
They are agile, strong, active dogs, both physically and mentally, which revel in new experiences. The flip side is that they bore easily and will unintentionally find trouble while looking for activities to occupy themselves with.
The cattle dog is very organized; many are known for putting their own toys away after playing.
At 19-inches tall and 30 to 60 pounds, they aren't huge dogs, but they're not the best choice unless you have plenty of wide-open spaces.
