New York : A Polish puppy no bigger than its owner’s mobile phone may be the smallest living dog on the planet.

The teeny terrier Meysi weighed just about 44.7 grams at birth and is now three months old and tips the scales at 92.1 grams.

Anna Pohl from Poland who was not initially sure the canine would survive is now submitting her puppy for consideration as the Guinness World Records’ smallest living dog on the planet, the New York Daily News reported.

“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.Pohl kept Meysi warm with her body heat and started feeding the terrier frequently.

“The worst was the first six weeks. Zero sleep. I was feeding her day and night, every half hour. Sometimes I ran out of strength, had to call out of work,” Pohl added.The petite puppy is barely bigger than Pohl’s cellphone or lip-gloss. “I have to keep Meysi in a cage when I’m not around because I’m afraid she’ll get stepped on,” Pohl said.

According to Guinness World Records guidelines dogs must be at least one year old to be recognised as the smallest dog.

The organisation does not recognise smallest puppy. The current record holder for smallest dog in terms of height is Boo Boo, a 4-inch tall female Chihuahua from Kentucky. The smallest dog in terms of length is Heaven Sent Brandy, a six-inch long female Chihuahua from Florida.

Guinness World Records does not recognise categories by weight because they do not want to encourage owners to overfeed or starve their pets.
