World's smallest dog, Beyonce, fits on an iPhone

• Tiny puppy was last out from a litter of five
• Revived after she was born with no heartbeat
• Now doing well but still needs hourly milk feeds

The puppy named Beyonce after one of the world's biggest pop stars could set the world's record for tiniest dog.

MEET the tiny pup vying for the title of world's smallest dog - a miniscule Dachsund mix who fits on an iPhone.

The 10cm pup called Beyonce was so tiny when she was born she could fit onto a spoon.

Rescuers at the Grace Foundation Animal Shelter in northern California plucked pregnant mum Casey from the streets and oversaw the birth of the five pup litter on March 8.

Animal rescuers in Northern California say that Beyonce was so small at birth that she could fit into a spoon.

Itty-bitty Beyonce was last out, but vets had to work frantically to revive her with chest compressions and mouth-to-mouth resuscitation when she was born with no heartbeat.

Now three-weeks-old, the pint-sized pup named after one of the world's most famous popstars is being fed hourly through a bottle.

To show just how small she is the Dachshund mix puppy, named Beyonce is photographed next to a cookie.

The proud team who brought her back to life have submitted an application to Guinness World Records to have her crowned world's smallest dog.

It would be a doggone shame if she missed out.
