The decision to end the life of 6-year-old Dolly was made after a veterinary examination confirmed the lung disease, a statement from the institute said.

In 1999, scientists noticed that the cells in Dolly's body — cloned from a 6-year-old sheep — had started to show signs of wear more typical of an older animal.
Somehow I feel this is ironic that she didn't live past the age that the doner sheep was at the time she was born.
