how long are most horses?
According to the Ontario Ministry of Agriculture, the average lifespan of a horse is 28 + 5 years. That means the average lifespan of a domestic horse is 25 to 33 years. Many horses go well beyond this average. Ponies tend to live longer with many ponies still serving as schoolmasters well into their 30s. A few ponies and horses may even reach the age of 40 or over. The oldest horse ever recorded was 52 years old.
The horse (Equus ferus caballus) is one of two extant subspecies of Equus ferus. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of today. Humans began to domesticate horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC.
