Pearl, a Chihuahua from Orlando, has been recognized by the Guinness World Records as the shortest dog ever. Standing at just 3.59 inches tall, she surpassed her aunt Milly, the previous record holder. Pearl has an active and calm temperament, enjoys sunbathing and playing with toys, and is often seen socializing with other dogs. Chihuahuas have a rich history and cultural significance, and Pearl's tiny size is truly remarkable. Although the overall record for the smallest dog ever goes to a dwarf Yorkshire Terrier, Pearl's achievement is still incredible.
