The average lifespan of a horse is between 20-30 years. This range differs for each horse and depends on varying factors, such as breed, lifestyle and environment.
Due to increased veterinary standards, many horses are now living into their 30s and even into their 40s. The oldest horse ever recorded was 62-year-old "Old Billy." In order to prolong a horse's life, owners should give extra attention and care to the animal's teeth throughout its life. For horses, good dental hygiene is necessary to avoid malnutrition and to maintain a healthy weight. Being conscientious about parasites is also a key step to prolonging a horse's life.
