The smallest dog on record was a Yorkshire terrier, who was 2.5 inches tall at the shoulder, 3.75 inches long from the tip of his nose to the base of the tail, and weighed 4 ounces. According to "The Book of General Ignorance," the dog died in 1945. For the smallest dogs living today, the current world record is shared by a Yorkshire terrier (shortest in height) and a Chihuahua (shortest in length). Whitney, the Yorkie, lives in England and is 3 inches tall at the shoulder. The Chihuahua, called Danka Kordak Slovakia, is 7.4 inches long and lives in Slovakia. Extremely tiny dogs are known for their frail health, so we hope others won't be trying for this dubious record.
