At 1.4 pounds and 4.9 inches tall, Ducky, a yappy short-coat Chihuahua from Charlton (Massachusetts, USA), holds the Guinness World Record for the world's smallest living dog (by height). Ducky succeeds Danka Kordak of Slovakia, a Chihuahua who measured 5.4 inches tall. The smallest dog ever, according to Guinness, was a dwarf Yorkshire terrier who stood 2.8 inches tall.
A tiny puppy named Beyonce, not much bigger than a business card, has defied odds by surviving. At a day old, Beyonce could fit in a tablespoon. Now, at a little more than 2 weeks old, weighs 4 ounces and is no bigger than an iPhone - setting the new world record for the Smallest puppy, according to World Records Academy. Beyonce is one of five puppies born to Casey, a Dachshund mix.
This 3-month-old Terrier named Meysi could be the world’s tiniest pup, weighing in at a measly 3.25 ounces. However, Guinness Book of World Records says she's not eligible to take the title till she turns 1. And although cute, the desire to breed the world's smallest or largest pets almost always comes at the cost of the animal's health & therefore, is ethically & morally WRONG to try & intentionally do.
