The 10 smartest dog breeds include the Border Collie, Poodle, German Shepherd, Golden Retriever and Doberman Pinscher. Shetland Sheepdog, Labrador Retriever, Papillon, Rottweiler and Australian Cattle Dog round out the list, according to Rover.com.
The Border Collie is a herding dog that controls flocks of sheep with its famously intense stare. The breed's intelligence allows it to master various canine sports like flyball, tracking and flying disc competitions. The Shetland Sheepdog was bred to herd as well as trained to ward off birds and sheep from farmers' gardens.
The Poodle was originally bred as a rugged water retriever despite its often elegant and prim appearance. Poodles shine at performance sports such as obedience, agility and hunting tests.
The German Shepherd is often trained to do guide and assistance work for the handicapped, and as a police and military service dog. The Doberman Pinscher is also suited for police and military work.
Golden Retrievers are natural athletes that excel at retrieving game for hunters, tracking and sniffing out drugs. The breed makes for ideal therapy and assistance dogs. The Labrador Retriever shares these traits and is also known as a fisherman's helper. Labs were originally used to haul nets, fetch ropes and retrieve fish from frigid North Atlantic waters.
