Canis ISSN: 2398-2942 Yorkshire Terrier Introduction Biological Data Introduction General information Originated in the West Ridings area of Yorkshire. Developed as a pocket-sized dog used by miners for ratting. Long straight hair requires regular grooming, even if clipped short. Size reduction has brought with it several medical problems, but had little impact on terrier nature of the dog. Typically energetic and dynamic, may need more exercise than its size and delicacy would imply. Makes an ideal companion.
