Identical twin puppies confirmed

Two puppies born in October are in fact identical twins, a team of veterinarians reports. This is the first time that a genetically confirmed set of identical twin dogs has been reported in the scientific literature.
"What happened in this case … would have been the same thing that happens in a woman when she has identical twins," Carolynne Joonè, a veterinarian and lecturer at James Cook University in Australia, and co-author of the report of the finding, told Live Science.That is, early during the mother dog's pregnancy, a fertilized egg split in two, creating two genetically identical embryos, Joonè said.
The Irish wolfhound puppies were first suspected to be twins when, during their birth last October in South Africa, veterinarian Kurt De Cramer observed that the two puppies had shared a single placenta. The puppies' mother had been straining to give birth for several hours and was taken to De Cramer, who performed a Cesarean section, Joonè said
