South Korean scientist Hwang Woo-suk revealed in the recently published issue of Nature that his research team successfully produced the world's first cloned dog, Snuppy. Cloned dogs have always been a difficult challenge in the field of cloning technology. The reason is that dogs have only 2 estrus cycles per year, and waiting for a dog to ovulate naturally is the only way to obtain its eggs. Moreover, when a dog ovulates, the eggs released by the ovaries are at an early stage of development, and only mature at the end of the fallopian tube, so successfully extracting high-quality dog eggs is quite difficult.

Cloned dogs have always been a difficult challenge in the field of cloning technology. The reason is that dogs have only 2 estrus cycles per year, and waiting for a dog to ovulate naturally is the only way to obtain its eggs. Moreover, when a dog ovulates, the eggs released by the ovaries are at an early stage of development, and only mature at the end of the fallopian tube, so successfully extracting high-quality dog eggs is quite difficult.

Cloned dogs are of great value in medical research, because in pathology, dogs are very close to humans. Dogs have 203 disease models, while pigs and cats have only 65 and 123 respectively.
