A puppy, so small it may qualify for the Guinness Book of World Records, had to be revived by mouth-to-mouth resuscitation and chest compressions when she was born.

The Grace Foundation, which takes in unwanted animals, said animal control picked up the puppy's pregnant mother, and she gave birth to a litter of five on March 8.

The foundation, which has called the Dachshund mix Beyonce, said she would soon be ready for adoption.

It has submitted an application to the Guinness Book of World Records to see if Beyonce is the world's smallest puppy.

Beth Decaprio, the Executive Director of the Grace Foundation in California, was speaking to BBC Radio 5 live's Tony Livesey.
