Border Collie
Descendants of the British Isles, Border Collies are consistently named first in every list of intelligent dog breeds. Border Collies are bred to serve as livestock herders; however, their superior cognition abilities, extreme athleticism, and friendly nature have made them the top contenders in various dog sports and cherished companion pets. And though owning a highly intelligent dog might sound tempting, Border Collies need a lot of physical and mental exercise. So, before getting a puppy, be sure you'll be able to meet its needs.
