Horse
Depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30 years. Uncommonly, a few animals live into their 40s and, occasionally, beyond. The oldest verifiable record was "Old Billy", a 19th-century horse that lived to the age of 62. In modern times, Sugar Puff, who had been listed in "Guinness World Records" as the world's oldest living pony, died in 2007 at age 56.
Lyphard
In 1996, Lyphard was pensioned from stallion duty at age 27 and lived another nine years. He was one of the oldest Thoroughbred horses in the world by the time he was humanely euthanized on June 10, 2005 as a result of the infirmities of his very old age.
