The Yorkshire Terrier began as a working ratter in the mills and mines of nineteenth-century northern England, where workers crossed small Scottish terriers to get a dog that could slip into tight spaces. Today's Yorkie is a toy dog of roughly four to eight pounds with a fine, silky, steel-blue and tan coat that grows like human hair and sheds little.
That terrier heritage shows in the personality. Yorkies are confident, curious and affectionate, quick to announce visitors, and often unaware of how small they are. In a city of close-set streets and shared walls, that alertness can mean a lot of barking without early training. Plan for regular grooming, patient house training and frequent small meals for young or very tiny dogs. Every Yorkie differs, so get to know the dog in front of you, not just the breed label.
