A horse needs consistent access to forage, fresh water, shelter, social contact, movement, and routine preventive care. These aren’t optional extras. Each one is fundamental to keeping a horse healthy, sound, and mentally stable. Whether you’re a first-time owner or evaluating your current setup, here’s what that looks like in practice.
Forage and Feeding
Hay or pasture grass is the foundation of every horse’s diet. A horse should eat roughly 2% of its body weight in dry forage per day. For a 1,000-pound horse, that’s about 20 pounds of hay daily. The absolute minimum is 1% of body weight, but that low end is typically reserved for horses in heavy work getting supplemental grain. Most horses do best when forage makes up the bulk of their calories.
Horses evolved to graze for 16 to 18 hours a day, so long gaps between meals cause problems. An empty stomach produces acid continuously, and without forage to buffer it, ulcers develop quickly. Splitting hay into multiple feedings throughout the day, or using slow-feed hay nets, keeps the digestive system working the way it’s designed to.
Grain and concentrates are only necessary when forage alone can’t meet a horse’s energy demands, such as during heavy training, lactation, or hard keeping. Many horses in light work do fine on quality hay, a mineral supplement, and salt.
Water and Salt
The average horse drinks 5 to 10 gallons of fresh water per day. That range shifts with temperature, workload, and diet. Horses eating dry hay need more water than those on lush pasture. Dehydration sets in fast and can trigger colic, so clean water should be available at all times, not rationed or offered only at certain hours.
Salt is the one mineral horses can’t get enough of through forage alone. The standard recommendation is about 1 to 2 ounces of plain salt per day for a horse at maintenance. A salt block in the stall or pasture gives horses the option to self-regulate, though many horses don’t lick enough to meet their needs. Adding loose salt to feed is a reliable way to close the gap.
Shelter and Stall Size
Horses need protection from wind, rain, and extreme sun. This can be a run-in shed in a pasture or a traditional stall in a barn. The shelter doesn’t need to be elaborate, but it does need to be available.
If your horse lives in a stall for any part of the day, size matters. The standard recommendation for a 1,000-pound horse is a 12-by-12-foot stall. Some barns manage with slightly smaller dimensions, but walls shorter than 10 feet in length aren’t advisable. Stall partitions should be at least 7.5 feet high to prevent a horse from getting a leg over the wall, with 8 feet being standard. Barn ceilings should sit at 10 to 12 feet, with 8 feet as the minimum to prevent head injuries.
Stall doorways are typically just over 7 feet tall and 42 to 45 inches wide, though a 4-foot-wide opening is easier and safer for leading horses in and out. Good ventilation inside the barn is just as important as the dimensions. Ammonia buildup from urine irritates the respiratory tract and contributes to chronic airway problems.
Daily Turnout and Movement
Horses are built to move. In the wild, they walk 15 to 20 miles a day while grazing. Confinement without adequate movement leads to stiff joints, digestive slowdowns, and behavioral problems like cribbing, weaving, and stall walking.
While researchers haven’t pinpointed an exact number of required turnout hours, the pattern in the scientific literature is consistent: daily turnout is significantly better than intermittent turnout, and longer durations produce more stable behavior and lower stress indicators. Predictable, routine turnout is also safer than sporadic access. Horses that move freely every day maintain steadier musculoskeletal conditioning, which reduces the risk of injury when they do get bursts of activity. If full-day turnout isn’t possible, aim for the longest stretch you can manage and supplement with riding or hand-walking.
Social Contact
Horses are herd animals, and isolation takes a real toll. A horse kept alone without any social contact is more likely to develop anxiety-driven behaviors like stall walking, weaving, and wood chewing. These aren’t just bad habits. They’re signs of psychological distress.
The ideal setup is turnout with at least one compatible companion. If that’s not feasible, being stabled where a horse can see, hear, and smell other horses makes a meaningful difference. Even interaction with people, goats, or donkeys provides some social stimulation, though it doesn’t fully replace horse-to-horse contact. When behavioral problems do appear, increasing social access, exercise, and roughage are the first interventions recommended before anything else.
Hoof Care
Hooves grow continuously, and without regular trimming, they crack, flare, and change the angles of the leg in ways that cause lameness. How often a farrier needs to visit depends on whether your horse wears shoes.
Shod horses generally need trimming and resetting every 6 to 8 weeks. Unshod horses in light use can go 10 to 12 weeks between trims, though many hooves are ready again by 5 to 7 weeks. Between farrier visits, rasping flares every two weeks helps maintain proper shape. Skipping or stretching farrier appointments is one of the most common causes of preventable soundness issues.
Daily hoof care matters too. Picking out hooves before and after riding removes rocks and debris, and gives you a chance to catch thrush, abscesses, or loose shoes early.
Dental Care
Horse teeth grow throughout their lives, and the grinding motion of chewing wears them unevenly. Sharp points and hooks develop on the edges of the molars, causing pain, difficulty chewing, and resistance to the bit. A dental exam includes a visual inspection and “floating,” which is the process of filing down those sharp edges.
Most adult horses need a dental exam once a year. Young horses in training may need checks every six months because their mouths are changing rapidly as baby teeth shed and adult teeth come in. Senior horses also benefit from more frequent exams, since older teeth are more prone to cracking, loosening, and developing gaps that trap food.
Vaccinations
Four vaccines are considered core for every horse in the United States, regardless of lifestyle or location. These protect against tetanus, Eastern and Western equine encephalomyelitis, West Nile virus, and rabies. All four target diseases that are either extremely dangerous or fatal, and exposure risk exists everywhere.
Beyond these core vaccines, your veterinarian may recommend additional ones based on geography, travel, and exposure to other horses. Influenza, rhinopneumonitis, and strangles are common risk-based additions for horses that attend shows, trail ride with groups, or board at busy facilities. Most vaccines are given annually or semi-annually.
Parasite Management
The old approach of deworming every horse on a rotating schedule every two months is outdated. Current veterinary guidelines recommend using fecal egg counts once or twice a year to identify which horses are shedding the most parasite eggs. Not all horses carry the same parasite burden, and blanket deworming accelerates drug resistance in worm populations.
The modern protocol is to deworm all horses at a baseline rate of once or twice a year, then target high shedders with additional treatments based on their fecal results. This approach keeps pastures cleaner while preserving the effectiveness of the limited deworming drugs available. Good pasture management, like picking up manure regularly and rotating grazing areas, reduces exposure further.
