史纳比（英文：Snuppy，2005年4月24日－）是世界上第一只透过克隆技术而诞生的狗，即首只复制狗。史纳比是一只阿富汗猎犬，由韩国首尔大学的黄禹锡教授所带领的一队科学家所制造。“Snuppy”这个名称其实是“SNU”（首尔大学的英文名缩写）及“Puppy”（小狗）合起来而成的。

克隆狗只一直都是克隆技术的一个挑战，原因是狗只在排卵时，卵子还未成熟。因此，科学家需要在短时间的排卵期内搜集足够作研究用的卵子。而研究员为了成功克隆狗只，他们把1095只受精卵放入123只狗妈妈体内，当中只有三个胚胎成功发育。不过，当中有一个胚胎流产、一只小狗在出世后三周因肺炎而离世，只有史纳比能够成功生存达三个月之久。

Snuppy (Korean: 스너피 a portmanteau of "SNU" and "puppy"; born April 24, 2005) is an Afghan hound, credited with being the world's first cloned dog. The puppy was created using a cell from an ear from an adult Afghan hound and involved 123 surrogate mothers, of which only three produced pups (Snuppy being the sole survivor). The team of 45 responsible for cloning Snuppy was led by biomedical scientist Hwang Woo-Suk, who was later found to have lied about his research on previous projects, however independent investigators discovered that Snuppy was a true clone. Snuppy has since been used in the first known successful breeding between cloned canines, after his sperm was used to artificially inseminate two cloned females, which resulted in the birth of 10 puppies in 2008. Replacement team leader and veterinarian Lee Byeong-Cheon used this technology to clone the first sterilized working dogs, Toppy.
