Observations

Horses suffer from a form of mechanical senescence in their teeth that limits their longevity. As in dogs (Canis familiaris), dwarf or miniature horses appear to live longer [0742]. One Icelandic miniature horse named "Tulle" is reported to have lived 57 years (Richard Miller, pers. comm.). Anecdotal evidence tells of a horse, called "Old Billy," that lived for 62 years in England, but that record is unverified.
