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.
Guide horse
A guide horse is an alternative mobility option for blind people who do not wish to or cannot use a guide dog. They are provided by The Guide Horse Foundation, founded in 1999 to provide miniature horses as assistance animals to blind users living in rural environments. There are several perceived advantages to using a horse rather than a dog. Miniature horses, with an average lifespan of thirty years, live much longer than dogs, and for those allergic to or frightened of dogs, a horse could make a good alternative. However, while a dog can adapt to many different home situations, a horse must live outdoors, requiring a shelter and room to move about when not on duty.
