Smallest Living Dog
Guinness World Records recognizes two categories for smallest dog – length and height. In both cases, and as with all animal size records, the claimant must be fully mature when measured – and they must be examined by a qualified veterinarian.
The world's smallest dog living in terms of height is Whitney, a Yorkshire terrier who measured 7.6 cm (3 in) to the shoulder on November 26, 2002. Whitney is owned by the UK's Christopher and Patricia Sheridan of Shoeburyness, Essex, UK.
The smallest living dog in terms of length is a long-haired chihuahua called Danka Kordak Slovakia, who measured 18.8 cm (7.4 in) long on May 30, 2004. Danka is owned by Ing. Igor Kvetko of Revúca, Slovakia.
