World’s first litter of IVF puppies have been born at Cornell University in New York

A surrogate mother dog has given birth to the world’s first litter of IVF puppies.

All seven pups, who have three sets of biological parents, are said to be healthy and doing well at Cornell University in New York.

They were born after 19 embryos created by in-vitro fertilisation were transferred to the host mother, a beagle.
