The world's smallest dog is making big headlines.

A tiny Terrier from Poland named Meysi only weights 1.58 ounces at birth three months ago, according to ABC News.

Meysi's owner, Anna Pohl of Jarocin, Poland, told her local newspaper she didn't think her dog would make it and that it took all of Pohl's strength to keep Meysi going. [SEE PHOTO HERE]

"The worst was the first six weeks," Pohl, who fed Mesyi with a syringe, told Gazeta Jarocinska, according to a translation. "[I got] zero sleep. I was feeding her day and night, every half hour. Sometimes I ran out of strength, had to call out of work."

Veterinarians told Pohl that they don't expect Meysi to grow anymore than 3.25 ounces, which is what she weighs now.

"It's a miracle Meysi is even alive," Pohl told her local newspaper, according to the New York Daily News. "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."

"Her sister is three times her size," Pohl said in a YouTube video. "She eats on her own now... but she's too small to bathe... She eats Gerber baby food on her own. You can tell by her round belly that she's got a good appetite."

ABCNews reported that the current titleholders of "world's smallest dog" are a long-haired, female Chihuahua named Boo Boo from Kentucky who is the smallest living dog in terms of height at 4 inches tall, and Heaven Sent Brandy, a female Chihuahua from Florida who is the smallest living dog for length at 6 inches "from the nose to the tip of the tail," according to the Guinness World Records website.

The Daily News reported that 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, so Meysi has some months to go to be in the running.
