2) Poodle
They are known for the foo-foo haircut but the intelligence quotient of these dogs is paramount. Originally bred in Germany for hunting birds and water retrieving, the poodles are good at herding as well. They were also used for bringing supplies at the time of battles. They are celebrated for their loving nature, trainability, intelligence and sense of humor.
1) Border Collie
The topmost place of the list goes to the Border Coolie without whom the list of the smartest dog would remain incomplete. They hail from the highland borders of England and Scotland and their maiden name is Scotch Sheep Dog. They are equipped with problem-solving intelligence and independent thinking. A Border Coolie named Chaser is the perfect example of the breed who knew 1022 toys by their name.
So which one is your favorite??
