The Border Collie is the smartest breed! I know I am biased, but there is some proof, scientists actually studied it. To find the smartest breeds, scientists tested each breed based on learning a series of new commands. Breeds were then ranked according to how many repetitions it took for them to understand and obey the first command.
For a list of the top ten smartest breeds and the list of the ten dumbest breeds out of the 80 tested check out one of my favorite blogs The Life of My Dog and their post here —> 10 Smartest Dog Breeds and…um…10 Least Smart Dog Breeds

Our Collie is certainly intelligent but often very excited so learning new things takes time. Whereas our Australian Shepherd (who didn’t make that list! Bah!) is calmer and takes to things more quickly.
