How long do horses live?

The British Horse Society says that “horses and ponies today live longer than ever, with many living into their 30s”, and that most horses show the first signs of ageing in their mid to late teens. As with any animal, breed, workload, and (most of all) the quality of care through their life all play a part.

Good nutrition, regular farriery, dental checks, and prompt veterinary attention all add years. A horse in its twenties may still be ridden lightly rather than fully retired. It's part of why the bond between owner and horse runs so deep, and why a horse memorial gift matters so much when that long partnership ends. For the practical side of ownership, see how much a horse costs. Putting a number on that lifespan in human terms is its own tangle: the published conversions disagree, as horse years in human years sets out.

No veterinary body publishes an official average, which is part of why quoted figures drift. The clearest published framing is Catherine McGowan's review Welfare of Aged Horses, in Animals in 2011, which treats a horse as aged or geriatric at 15 years or over and as very old at 30 or more, and records that horses "often live to be in their 30s with some reported to live into their 40s or even longer". Owners draw the line earlier than the vets: the same review cites survey work in which owners considered a horse old at an average age of 22.
