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.
Thoroughbred Retirement Foundation
The Foundation says that the "sad truth is that a vast majority of the general public and even many racing fans are unaware of the sad fate that awaits thousands of Thoroughbreds each year. They assume each animal is assured a safe and graceful retirement once its racing days are over. Their perception of the "Sport of Kings" is one where great personal wealth and lifelong benevolence to all horses are givens. Unfortunately, it is a perception that does not reflect reality."
