The teeny terrier Meysi, who weighed about 1.58 ounces at birth, is unwittingly vying for the title of World's Smallest Living Dog. But her owner Anna Pohl of Jarocin, Poland was not initially sure the cute canine would survive.

"It's a miracle Meysi is even alive. When her mother Pusia started giving birth to her litter, I thought at first she had passed a piece of placenta and was about to throw it away when it suddenly started moving," Pohl told the local paper, the Gazeta Jarocinska.

Guinness World Records guidelines specify that dogs must be at least one year old to be recognized as the smallest dog. The organization does not recognize smallest puppy yet.
