• Sylvia, a Yorkshire Terrier owned by Arthur Marples of Blackburn, England, was the smallest dog in recorded history. The dog passed in 1945 when she was almost two years old. At that time, the dog was only 2.5 inches tall at the shoulder, measured 3.5 inches from nose tip to tail, and weighed 4 ounces.
• For 1995 through 2002 Guinness World Records listed a Yorkshire Terrier named Big Boss, as the smallest dog in the world. Big Boss was listed at 4.7 inches ( 11.94cm) tall.
• A Yorkie named Thumbelina, 5.5 inches tall and 8 inches long, held the Guinness World Record for smallest living dog up until 1995.
• Tiny Pinocchio, an unusually small Yorkie, had appeared on many TV shows including Oprah and the Today Show. This poor little thing was only 1 pound (.45 kg) and only lived 2 years and 3 months most likely due to her dangerously small size.
