The smallest dog in the world according to the Guinness World Records is the Chihuahua breed. The smallest Chihuahua in the world was recognized as the smallest dog in the world in 2015 and was named Milly.
Milly was born in 2011 in Puerto Rico and was owned by Vanesa Semler and Edwin Davila. When Milly was a small puppy, she was so small that they had to care for her with a syringe to make sure she was getting food and water.
When Milly grew up, she became a world celebrity and appeared in many television shows and articles. She was so small that she could fit in a pocket or a small handbag. Milly was very sweet and friendly and loved to play with other dogs.
Unfortunately, Milly died in 2017 at the age of just six. Her owners said that Milly had liver problems and they could not save her. However, her memory lives on as the smallest dog in the world and reminds us how amazing and diverse creatures dogs are.
