The Yorkshire Terrier started out as a working ratter in the mills of nineteenth-century Yorkshire and Lancashire, where workers crossed several small Scottish terriers. Adults usually weigh about four to eight pounds and stand seven or eight inches tall, with a fine, silky blue-and-tan coat that grows like human hair and sheds very little.
Yorkies are bold, affectionate and quick to announce visitors, so a dog that's cuddly on the couch may still have strong opinions about the neighbors, a passing raccoon or a bigger dog on the path. Expect regular brushing, professional grooming every six to eight weeks and close attention to their teeth. Dogs vary, so a shelter Yorkie's own personality matters more than the breed description.
