Sometimes, I wish I had a clone. Lou did too, when his beloved dog Missy passed. Time for re-pet — three pups cloned in Korea from the same deceased mother.
They have no father, but three mothers contributed to their birth: Missy for DNA, another for an embryo (and mitochondrial DNA), and a third surrogate mom for implantation and fetal development.
When asked how he tells them apart, it is entirely by age and RF tag implants. The cloned dogs not only have the coat pattern of the deceased Missy, but they also share her eccentricities, like barking at people wearing hats, loving to eat broccoli, and cowering away from house cats. He calls them Near Missies.
Because of their random estrous cycles, dogs are among the most difficult animals to clone.
