This is first ever recorded case in the scientific literature of identical twin puppies.
Outside of humans and one species of armadillo, identical twins isn’t a common occurrence. But a rare event might have taken place at South Africa’s Rant en Dal Animal Hospital in Mogale City.
Vet Kurt de Cramer was performing a routine Caesarean section when he noticed something odd. The vet noticed an “unusual bugling” in the dog’s uterus, according to the BBC. He thought it was just a lump, but soon discovered two foetuses attached to the same placenta with umbilical cords.
“When I realised that the puppies were of the same gender and that they had very similar markings, I also immediately suspected that they might be identical twins having originated from the splitting of an embryo,” De Cramer told the BBC.
A team then set out to investigate, obtaining blood samples from the pups. While there were minor differences in their markings, the tests revealed that the pups were genetically identical.
This is the first such recorded case in the scientific literature.
