The Yorkshire Terrier started out as a mill and mine ratter in nineteenth-century northern England, and that working background still shows. Adults typically weigh 4 to 8 pounds and wear a fine, silky coat that grows continuously like human hair and sheds very little. That coat tangles without regular brushing, so grooming is part of the deal.
A Yorkie's confident terrier streak plays out on sidewalks and in shared buildings: many are curious, quick to announce visitors and bolder than their size suggests around bigger dogs. Gentle socialization and steady, reward-based training go a long way. Dogs vary, and how a particular Yorkie handles children and other pets matters more than breed reputation. Expect an indoor companion that wants to be near you.
