Unfortunately, buying the puppies wasn't going to stop the shop owner from making dog tonic - once the puppies were gone, the owner would probably just get more dogs to use.
Even so, Yi knew she had to save them. So she went inside the shop, paid for them and took the puppies home with her.
She named the five puppies Geum, Eun, Dong, Jiho and Jini. Geum, Eun and Dong were siblings, and Jiho and Jini were siblings from another litter.
