When I was recently watching a horse work at the training center, I realized that most of the racehorses in training are incredibly young. This made me think about their lifespan and how long they’re likely to live, so I decided to do some research to find out.

On average a racehorse lives between 22-28-years, The lifespan of a horse is mostly determined by genetics, diet, and lifestyle. Just like humans some horses will live much longer healthier lives while others will die young.

The lifespan of a racehorse isn’t any different than that of other athletic riding horses. The same factors and considerations used to determine the lifespan of the average horse are also used for a racehorse.

Quick Links:

Today’s running horse is much more likely to outlive his predecessor. Many factors contribute to the increased lifespan of horses, including better nutrition and advances in veterinary medicine. Let’s take a look at some of the factors that affect a horse’s lifespan. See Ontario Horse Industry study.

Genetics plays a role in a horse’s life expectancy.

How traits such as hair color, eye color, and risk for the disease are passed (“inherited”) from parents to their offspring. As with humans, good genes are a major benefit to strong health and extended life expectancy in horses.

Large draft breeds typically have a shorter lifespan than lightweight breeds and breeds with high instances inbreeding also live shorter lives. The Friesian horse breed is a good example of this, their average lifespan is only 16 years.

What factors affect a horse’s lifespan?

Some horse lives longer than others, is it all genetics, or is there other factors that play a role?

A healthy diet can add years to a horses’ life.

The kind and amount of food prescribed for the horse. Depending on the horse’s needs their diet may need to be adjusted. The food fed to a horse is his life support system.

A horse must be fed according to his needs. Food is fuel for a horse, if the horse is a young athletic horse in training he will need more fuel, vitamins, minerals, proteins and other nutrients.

However, if the horse has retired from the track and turned out in the pasture he will not need as much fuel. Keep an eye on your horse and if you are feeding good quality hay and some feed and the horse is maintaining his weight and energy then his dietary needs have likely been met.

Ensuring a horse has essential nutrients increases its lifespan.

An adequate supply of essential nutrients (as vitamins and minerals) in the diet to enhance health and prevent malnutrition or disease. As horses age their nutritional needs will change, being aware of this will help to keep a horse healthy.

A horse maintained with good nutrients throughout his life will have a much longer and enjoyable life than a nutrient-deprived horse.

Horse’s without exercise have shorter lives.

Exercise is necessary for the overall health of a horse. Not just physically but also emotionally. An isolated horse gets depressed and is physically stymied.

Turn out time is one of the most important things to ensure a healthy horse. Free movement outside of a stall or small pasture assists in muscle development and helps to prevent arthritis in the joints. More pasture time leads to better health.

Wellness check-ups extend a horse’s life.

Regular veterinary examination and preventive medical treatment for disease and overall healthcare for the horse will help extend the life of a horse.

Parasite control and teeth maintenance are critical to the health of a horse. The inability to properly chew foods can result in malnutrition, weight loss, and colic. 

What you can expect as your horse ages.

Horses over the age of 15 years represent a significant proportion of the equine population. It is essential to their well being to be able to recognize the diseases that affect them and the steps we can take to care for our aging friends.

The following are some of the common diseases horses contract when they get older:

Intestinal lipoma

An intestinal lipoma is a fatty tumor, which sometimes leads to strangulation colic, a condition that is often fatal in older horses. The mean age of horses with strangulation lipomas is over 19 years old. As horses age their risks of lipoma increases significantly.

Cardiovascular health

Cardiovascular issues become more prevalent in aging horses because, with time, walls of the heart valves thicken, and the valves may fail to close correctly. This failure allows blood to leak through the valves, which causes the heart to work harder.

When the heart has to compensate for the leaky valve, the horse’s heart wears down, and cardiac efficiency is compromised. The condition is evident in the horse’s increased resting heart caused by its body’s attempt to maintain blood pressure.

Cardiac diseases, such as a leaky valve, can be fatal in some cases but assuredly affect a horse’s ability to perform, and the horse may be unsafe to ride. 

Pituitary Pars Intermedia Dysfunction (PPID)

Pituitary Pars Intermedia Dysfunction (PPID), is the disease most commonly associated with old age in a horse. It is often referred to as equine Cushing’s disease.

Horses of any age can develop this disease however, older horses are more at risk. This incurable but treatable disorder of the pituitary gland’s pars intermedia is characterized by excessive hair coats, delayed shedding, muscle wasting, abnormal fat distribution, laminitis, recurrent infections, and more. 

PPID is a common disease in older horses; however, the pathology and progression of PPID are not well known. The most reliable way to diagnose the disease is through recognition of the clinical characteristics the horse displays and blood tests.

The most effective treatment is to improve the horse’s overall health care, including body clipping, dentistry, and nutrition. If the condition worsens, some drugs are available to treat the symptoms of PPID.

Teeth and gum issues

Dental issues in geriatric horses create a myriad of problems. Horses’ teeth have a finite length. Various factors, such as genetics, dental management, and type of diet, play a part in the rate teeth, are worn. 

As horses age, its teeth naturally wear down and fall out. As this condition advances, the horse gets to the point it can no longer chew, which leads to malnutrition and possible death. Additionally, older horses struggle to maintain weight during periods of extreme cold, even when fed appropriate diets.

Skin cancer

Skin cancer is common among aging gray horses. This can lead to tumors in numerous areas of the body including the anus. If this happens it could result in blockage of the stool.

Musculoskeletal Issues,

Musculoskeletal Issues, these conditions manifest usually from a combination of arthritis and soft tissue diseases such as tendonitis or desmitis (tendon or ligament inflammation, respectively).

Racehorses and other horse that has been used for athletic purposes are prone to developing arthritis as they age, this can progress to the point it interferes with a horse’s day-to-day function. To prevent small problems from evolving into significant issues, have your horse seen regularly by a veterinarian and farrier.

Age-related deaths

The causes of death of most horses are not very dissimilar to the cause of death of humans. It is the sum of one or more gradually worsening conditions.

According to a study of deceased horses 15 years old and up from the University of Kentucky’s Veterinary Diagnostic Laboratory, the causes of death for most geriatric horses were disorders of the digestive system and those of the cardiovascular system.

About half the cardiovascular cases were caused by a uterine artery rupture, which is considered one of the possible complications for broodmares 15 years of age and up. Most digestive issues likely manifested as colic, which is still the most common cause of death for all horses.

How long does a horse live before he is considered old?

We recently watched our friend compete in team roping on an eighteen-year-old Quarter horse, in horseracing that horse would be considered ancient. Thinking about the ages of his horse made me wonder what most people consider and old horse.

In the United States, most horse owners consider a horse to have reached old age status at 20. In Europe and Australia, a horse is considered to have reached old age at 15 years of age.

Over the last decade, people in the United States have become more attached to their horses than their forbearers. Even racehorse owners have begun to bond more with their horse and this ultimately results in better long term care for aging horses.

Horses are living longer today. 

The National Animal Health Monitoring System (NAHMS) surveys horse owners, industry stakeholders, and government officials periodically to gain an overview of the horse industry based on responses from farm owners with more than five horses.

In its 1998 study, the NAHMS program unit found that 7.5% of U.S. horses were 20 or older, while in 2015 it found that 11.4% of U.S. horses were 20 or older. Of that 11.4%, 1.5% were 30 or older. https://thehorse.com/160313/the-price-of-longevity-senior-horse-health-needs/

Below is an interesting chart that compares horse ages to human equivalent ages. This is based off research completed in 2003 as published by Equine Resources International and referenced in ttps://www.thesprucepets.com/comparing-horse-to-human-age-1887320

As with humans age is just a number. Some horses at the age of 15 will begin to show symptoms associated with aging, while other horses will look the picture of health at 30 years old.

Horse breed lifespans differ.

It seems the smaller the horse the longer the life. It is not uncommon for a pony or miniature horse to live into their mid 30’s and the riding horse to start showing his age in his mid 20’s while draft horses have the shortest life span.

Below is a chart of some of the different horse breeds with their corresponding lifespan.https://horseislove.com/how-long-do-horses-live/

How old is the oldest horse?

When I was researching information horse lifespans, I read a lot about horses that lived exceptionally long lives, this made me curious to know what is the oldest a horse has ever.

Sixty-two years old is the record for the oldest horse. The horses’ name was Old Billy. It is believed that he was born sometime in 1760 in Woolston, Lancashire, England. 

Old Billy was owned by Mersey and Irwell Navigation and spent his life working as a barge horse, dragging barges in the canals from the shore.


Do horses sleep standing up? 

Seeing horses standing in the pasture not moving makes me wonder if they are sleeping or relaxing. I thought it would be interesting to find out if horses only sleep standing.
Horses do sleep standing up; they have a stay apparatus that allows them to lock their legs and fall into a light slumber; they need to lie down to get a good deep sleep.

I love animals! Especially horses, I've been around them most of my life but I am always learning more and enjoy sharing with others. I have bought, sold, and broke racehorse yearlings. I have raised some winning horses and had some that didn't make it as racehorses, so we trained them in other disciplines. Miles Henry
