Senior Horse Care Guide: How to Care for an Older Horse

Many horses begin to show age-related changes in their mid-to-late teens, although some stay remarkably youthful longer. In practical care terms, many vets start watching horses more closely for senior issues around 15 to 18 years old, especially if there is weight loss, stiffness, dental wear, or endocrine disease.

Age alone does not define health status. A 22-year-old horse in regular turnout with good teeth and stable weight may need less intervention than a 16-year-old horse with PPID, arthritis, and poor chewing.

Senior horse care usually centers on five basics: body condition, dental function, hoof balance, mobility, and hydration. Check your horse's appetite, manure, water intake, attitude, and ease of movement every day. Run your hands over the topline, ribs, hips, and neck regularly so weight changes do not sneak up on you.

Routine matters. Older horses often do best with consistent turnout, predictable feeding times, easy access to water, shelter from weather extremes, and enough space at feeding stations so they are not pushed away by herd mates.

Aging horses may digest forage less efficiently, and worn or missing teeth can make long-stem hay harder to chew. If your horse drops feed, takes a long time to finish meals, loses weight, or passes long fibers in manure, ask your vet whether a dental exam and ration review are needed before changing feeds.

Some seniors do well on hay plus a ration balancer. Others need soaked hay cubes, hay pellets, beet pulp, or a complete senior feed that can be fed as a mash when chewing is limited. Horses with PPID, insulin dysregulation, or laminitis risk may need lower sugar and starch diets, so feed changes should be matched to the horse's medical picture.

Older horses commonly develop worn teeth, loose teeth, wave mouth, periodontal disease, diastemata, and other age-related dental problems. These issues can reduce chewing efficiency and contribute to weight loss, choke risk, and feed quidding.

Many senior horses need a dental exam at least once a year, and some benefit from exams every 6 months. If your horse has bad breath, drops feed, resists the bit, loses weight, or eats more slowly than before, schedule a visit with your vet.

Regular movement helps many older horses stay more comfortable. Daily turnout and light exercise can support joint mobility, circulation, gut motility, and mental well-being. Warm up longer, cool down gradually, and avoid sudden jumps in workload after time off.

Not every senior horse needs retirement. Some thrive with light riding or groundwork, while others are happiest with pasture turnout and gentle hand walking. The right plan depends on soundness, hoof health, muscle condition, and any underlying disease.

Consistent trimming or shoeing remains essential in older horses. Good hoof balance can reduce strain on joints and soft tissues, and it becomes especially important if your horse has arthritis, conformational changes, or laminitis risk.

Call your vet sooner rather than later for new stiffness, shortened stride, reluctance to turn, frequent stumbling, or a change in how your horse stands. Mild lameness in a senior horse is often manageable, but it should not be ignored.

Preventive care often becomes more valuable with age. Many vets recommend annual or twice-yearly exams for senior horses, with testing guided by symptoms and risk factors. Depending on the horse, this may include CBC and chemistry testing, ACTH testing for PPID, insulin and glucose testing, fecal egg counts, and targeted imaging or lameness workups.

Vaccination and parasite control should also be individualized. Current AAEP guidance emphasizes fecal egg count-based parasite control rather than fixed-interval deworming for every horse year-round.

Older horses are more likely to develop arthritis, PPID, dental disease, muscle loss, weight loss, recurrent choke, melanoma in gray horses, and some forms of colic. Some also become less resilient in winter or during hot weather because they have a harder time maintaining body condition and hydration.

Contact your vet if you notice weight loss, a long curly haircoat, increased drinking or urination, repeated foot soreness, recurrent infections, quidding, chronic loose manure, or a clear drop in comfort. These signs may point to manageable conditions, but they need a proper workup.

Routine senior care costs vary by region and how much support your horse needs. A basic wellness visit may run about $150 to $350, annual dental care often falls around $250 to $600, routine bloodwork may add $120 to $300, ACTH or metabolic testing may add roughly $100 to $250, and farrier care commonly runs about $60 to $250 per visit depending on trim versus shoeing.

Monthly feed costs can also rise if your horse needs soaked forage products or complete senior feed. Many pet parents spend about $80 to $300 or more per month on specialized senior feed and supplements, not including hay, boarding, or medications. Your vet can help you prioritize the changes most likely to improve comfort and maintain weight.
