Most problems in a barn announce themselves quietly. A horse that leaves half its morning hay, stands apart at the fence or drinks less than yesterday is telling its owner something days before the vet bill arrives. This horse care guide starts with the habits that catch trouble early, then hands off to longer guides on manure, intestinal stones, trails, endurance and racing.
Horse care for California horse owners differs from the textbook version in a handful of specific ways, and those get their own section further down.
What horse owners look at before the first scoop of feed
Vital signs are the baseline. A resting adult horse has a temperature of about 99 to 101°F, a pulse of roughly 28 to 44 beats a minute and takes 8 to 16 breaths a minute. Owners who have measured those numbers on a healthy day, with a thermometer and two fingers under the jaw, spot a change within seconds.
The numbers matter less than the pattern. Appetite, manure, water, attitude: four things, checked at the same time every morning. A pile that is smaller, drier or missing says more about gut health than any gadget, which is why the manure guide spends time on what normal looks like before it gets to composting.
Legs come next. Run a hand down each one, feel for heat or a new puffiness around a joint or tendon, then watch the horse take a few steps. A small swelling found on Tuesday is cheap to deal with.
The same swelling found on Friday, after a ride, is not.
A five-minute morning check
Done at the same time each day, in the same order:
- Appetite: last night’s hay finished, and interest in the new feed.
- Water: the bucket or trough level against yesterday’s.
- Manure: amount, moisture and color against what is normal for this horse.
- Attitude: ears, eye and stance, and whether the horse is standing apart or lying down at odd times.
- Legs and feet: heat, swelling, a stone in a hoof, a loose shoe.
- Skin: cuts, lumps and rubs where tack sits.
- Temperature, pulse and breathing: taken only when something looks off, and compared with the horse’s own baseline.
Feed, hay and water: the daily budget
Horses eat roughly 1.5 to 2 percent of their body weight in forage each day, so a 1,000-pound horse gets 15 to 20 pounds of hay. The hay calculator turns a weight into pounds a day and bales a week. A flake is not a unit of measure. One bale may break into three-pound flakes and the next into eight-pound ones, and weighing the morning feed for a week corrects years of guessing.
In California the hay decision is mostly grass or alfalfa. Alfalfa carries more protein and calcium and suits thin or hard-working horses. Some of it is grown on serpentine soils, which are high in magnesium, and a diet built mostly on that hay, fed to a horse that spends the day in a stall, is the pattern most often linked to enteroliths in horses. A grass-based ration with limited alfalfa is the usual middle path. The exact ratio is a question for an equine vet who knows the animal.
The full ration, from pasture and hay to grain, salt and the plants that make horses sick, has its own page on what horses eat. Water is the part owners underestimate. An average horse drinks about five to ten gallons a day, and much more in summer heat or after hard work. Scrub buckets weekly and troughs more often in July, when algae grow in a few days. Plain salt should be available all year.
Hooves, teeth and the vet calendar
Feet first. Pick them out every day, which takes two minutes per horse and finds stones, cracks, loose shoes and the black, foul-smelling signature of thrush. A farrier trims most horses every six to eight weeks, shorter in the growth flush after spring rain, and the hoof care guide covers daily picking, thrush, abscesses and when to call the vet.
Teeth need a vet or equine dentist once a year. Horse teeth keep erupting for decades and wear into sharp points that cut cheeks, which shows up as dropped feed or head tossing under the bit before anything is visible in the mouth. The page on horse dental care explains floating, the signs of a sore mouth and what changes with age.
Day-to-day handling has three more guides. Grooming doubles as a daily health check, and how to groom a horse walks through the tools and the order of work. Horse body language covers what ears, tail and posture say before a horse acts. For the stable itself, there is a page on horse bedding and one on horse stall size.
Vaccines follow the core list from the American Association of Equine Practitioners: tetanus, eastern and western equine encephalitis, West Nile virus and rabies. Anything beyond that, such as strangles or influenza, depends on how often the horse travels and mixes with others. The horse vaccine guide sets out the core and risk-based shots and a yearly schedule for California. Deworming has shifted from calendar dosing to fecal egg counts, so each horse is treated according to what it actually carries.
Why California changes the routine
Horse care for California horse owners starts with heat and dust. Dry lots are common here, and a horse eating hay off sandy ground slowly swallows sand, which can settle in the gut and cause colic. Feeding from mats or a hay net keeps it out of the ration.
Wet winters bring the opposite problem. Mud makes thrush and rain rot likely, and a horse standing in it for weeks needs a dry place to get out of it and a daily look under the blanket.
West Nile virus is reported in California horses most years, which is the reason it sits on the core vaccine list. Valley fever, a fungal infection carried in dust, also occurs in horses in the San Joaquin Valley and southern deserts, and any chronic cough or unexplained lameness there is worth mentioning to the vet.
Then there is fire. Anyone keeping horses in the state should know two evacuation routes, keep halters with a phone number on them, and practice loading a nervous horse in daylight rather than in smoke. Many counties run volunteer animal-evacuation groups that will help but cannot reach every barn.
Horse care through the California year
Horse care follows the calendar more closely than most new owners expect, and California adds a few turns of its own.
Spring brings new grass. A horse that has eaten dry hay all winter can founder on a few hours of lush pasture, so turnout time is built up over a couple of weeks rather than days. Spring is also the usual time for vaccines, a farrier visit, shedding and a full tack check before riding picks up.
Summer is about water, shade and flies. Troughs get scrubbed more often, hard work moves to the cool hours after dawn, and fly control, from masks and sheets to daily manure removal, starts before the population peaks. A horse that sweats very little or stops drinking in hot weather gets a call to the vet.
Fall is fire season across most of the state. It is the time to service the trailer, check tires and hitch, rehearse loading and pack a go-bag with halters, lead ropes, copies of vaccination papers and a few days of feed, alongside a stocked horse first aid kit. Hay stored under cover before the first rains keeps better, and bales that smell musty or throw dust are better returned than fed.
Winter means mud in most areas and real cold in the mountains. Hooves need a dry patch of standing ground, rain rot shows up under blankets, and a blanketed horse still needs a hand run over the ribs every week, because a thick coat hides weight loss. The dental check often falls here, while work is slow.
None of this is exotic. It is the daily checks above tied to a calendar, and owners who write that calendar down once rarely miss a step.
A guide to the seven doors above
Treat this horse care guide as an index: the doors at the top of the page each open one subject in depth. Manure management on small acreage covers composting, storage and runoff, the topic most owners deal with every single day and read about least. The page on enteroliths explains the stone problem that California vets see more than most.
For riding, the riding hub is the starting point. Owners who want somewhere to go with the horse can read the guide to horseback trail riding in California. Those who want a longer day can try endurance riding for beginners, the sport that grew out of cavalry-style distance tests and now fills weekends from the Sierra foothills to the desert.
Racing has its own corner. The history of horse racing runs from Greek chariot contests to the Santa Anita meet, and the page on how to pick a winning horse explains what the form guide prints and how handicappers read it, without any advice on wagering. For the film and print side, racing in popular culture follows horses from Muybridge’s cameras in Palo Alto to the Hollywood studios.

Horse care questions, answered
What does horse care for California horse owners involve in summer?
Heat and dust drive the routine. Water use climbs sharply, shade and airflow matter more than blankets ever do, and hard rides move to early morning. Dry ground adds sand and dust, so feeding from rubber mats and watching for cough or loose manure is part of the season.
How much hay does a horse need each day?
Most adult horses eat 1.5 to 2 percent of their body weight in forage daily, roughly 15 to 20 pounds for a 1,000-pound horse. Weigh a few flakes to learn what a flake means in your bales, since the weight varies a lot from one bale to the next.
How often should a horse's hooves be trimmed?
Every six to eight weeks suits most horses. Fast-growing hooves, long wet winters or shoes can shorten the interval. Picking out the feet daily is the cheaper habit, because it is how stones, thrush and loose shoes get noticed early.
Which vaccines do horses need in California?
Tetanus, eastern and western equine encephalitis, West Nile virus and rabies are the core vaccines recommended for every horse in the United States. Others depend on travel, contact with other horses and local disease reports, so the schedule is set with a vet who knows the horse.
How can an owner tell if a horse is dehydrated?
Dry, tacky gums, sunken eyes and skin that stays tented for more than a second or two after a pinch on the shoulder all point that way. A horse that stops drinking, passes dry manure or seems dull in hot weather needs a vet, not a wait-and-see afternoon.
How many acres does one horse need?
A common rule of thumb is one and a half to two acres of good pasture per horse, which rarely applies in dry parts of California. Many owners keep horses on dry lots or small paddocks and feed hay year round, which is why manure and runoff management matter so much.
Where should a first-time owner begin with horse care?
With the boring parts: a vet and farrier lined up before the horse arrives, a safe fence, clean water, and a written list of normal vital signs for that animal. Riding goals can wait a month. Routines are easier to build while the horse is still new.
When does daily horse care turn into a call to the vet?
Repeated rolling or pawing, no manure for several hours, a horse that will not put weight on a leg, a wound near a joint, a temperature above 102°F or no interest in food all justify a call right away. A phone call that turns out to be unneeded costs far less than one that came too late.
