Joone’s response to the doubts

As this video was gaining popularity some people raised the question if they really were the first ever case of monozygotic pups? To which Joone responded with this statement, “There have been rumors about twins in dogs before. We just happened to be lucky enough to be able to confirm it genetically. Believe it or not, the only common examples of animals that frequently give birth to identical twins are humans or 9-banded armadillos. And for now, Cullen and Romulus remain the only confirmed case of identical twin pups on the planet.”
