The Yorkshire Terrier started as a working ratter in the mills and mines of nineteenth-century northern England, where workers crossed several small Scottish terriers. Today's Yorkie weighs roughly four to eight pounds and wears a fine, silky, steel-blue and tan coat that grows like human hair and sheds very little.
Behind the lapdog look is a confident terrier. Yorkies bond closely with their people, travel well and notice everything, which is why many bark at footsteps in a hallway. They're fragile around rough play and prone to dental disease, so adopters should plan for regular grooming, patient house training and small, frequent meals for young or very small dogs. Temperament varies from dog to dog, so spend time with the Yorkie you're considering.
