The Yorkshire Terrier began as a working ratter in the mills and mines of northern England, which explains the big attitude in a body that usually weighs around seven pounds. The fine, silky steel-blue and tan coat grows like human hair and sheds very little, though it needs regular brushing and professional grooming to stay free of tangles.
In Evanston, that compact size suits walkable blocks and smaller homes, and most Yorkies are happy with short outings. Their terrier boldness shows up as barking at visitors and confidence around much bigger dogs, so a harness, a secure leash and calm introductions on busy sidewalks help. Every Yorkie differs, and an adult may be calmer or more reserved than the stereotype.
