Yorkshire

Origin: England; first improvement in the breed was made in the Yorkshire region and surrounding countiesfirst imported to the United States in 1893Characteristics: face should be broad with a medium dish and the snout should be medium in length with a broad nostrilears should be medium to large in size and erect, yet some today have ears tilted forwardjowl should be reasonably trimall white in color; black hair or pigmentation disqualifies for registry; black or bluish skin pigment is discriminated againstSlide17
