My answer is to name the Canaan Dog, Carolina Dog, Korean Jindo, and Basenji.
At one time, the aforementioned breeds were regarded as landraces (and there are more if I include breeds whose ancestors were primitive, aboriginal, or village dogs).
Landraces typically evolve through natural processes, often in isolated areas, which helps maintain their genetic integrity. Over time, a person or people identify certain populations of dogs to be so consistent as to resemble a breed.
