Horse Preventive Care Schedule: Vaccines, Deworming, Dental, and Wellness Exams

Most adult horses benefit from at least one full wellness exam each year, and horses older than 20 often do better with exams every 6 months. During these visits, your vet may review body condition, weight trends, heart and lung sounds, skin and coat, eyes, feet, musculoskeletal comfort, manure quality, nutrition, travel plans, and vaccination history. This is also a good time to discuss Coggins testing, health certificates, and biosecurity if your horse shows, races, boards, or ships.

A practical annual plan often bundles four core areas: vaccines, parasite control, dental care, and wellness screening. Many barns schedule a spring appointment before insect season and a fall appointment before winter management changes. That timing can make it easier to stay current without over-treating.

Core vaccines are recommended for all horses because the diseases are severe, widespread, or important to public health. In adult horses, these typically include tetanus, rabies, West Nile virus, and eastern/western equine encephalomyelitis. Horses already vaccinated usually receive annual boosters, often in spring before mosquito season for vector-borne diseases. Adult horses with no vaccine history commonly need an initial 2-dose series for several core vaccines, followed by annual revaccination.

Risk-based vaccines are chosen with your vet based on geography, travel, herd density, age, pregnancy, and exposure. Common examples include equine influenza, equine herpesvirus-1/4, strangles, Potomac horse fever, botulism, and leptospirosis. Horses under 5 years old, show horses, breeding horses, and horses in high-traffic barns may need some boosters every 6 months rather than yearly.

Modern parasite control is less about frequent routine deworming and more about using testing to guide treatment. The AAEP recommends fecal egg counts once or twice a year to sort horses into low, medium, and high shedders, plus annual fecal egg count reduction testing to make sure the dewormers used in your herd still work. Current guidance also advises against deworming every 2 months year-round or blindly rotating drug classes.

Cornell classifies adult horses with 0 to 200 eggs per gram as low shedders, 200 to 500 as moderate shedders, and more than 500 as high shedders. Low shedders may need only baseline treatment once or twice yearly, while moderate and high shedders may need more targeted treatment based on season, pasture pressure, and herd management. Fecal results should be interpreted with your vet because egg counts do not directly measure disease severity or every parasite stage.

Dental exams are preventive, not cosmetic. Sharp enamel points, uneven wear, retained caps, hooks, ramps, and painful mouth lesions can affect chewing, weight maintenance, bit comfort, and behavior. Mature horses should have a thorough dental exam at least once a year. Horses 2 to 5 years old often need exams twice yearly because permanent teeth are erupting and the mouth changes quickly during that period.

Management matters too. Horses grazing freely on pasture may need yearly dental prophylaxis, while horses kept in stalls and fed mostly hay and grain may need oral exams and preventive care twice yearly. Many dental procedures are done on the standing sedated horse with a speculum and good lighting, which also makes it a convenient time for your vet to complete a more detailed oral exam.

Spring: wellness exam, core vaccine boosters, review risk-based vaccines before travel or show season, fecal egg count, and parasite-control planning. In mosquito-heavy regions, spring timing is especially important for West Nile and encephalomyelitis vaccines.

Summer: monitor body condition, hydration, pasture quality, fly control, and travel-related infectious disease risk. Some higher-risk horses may need 6-month influenza or herpesvirus boosters.

Fall: repeat fecal egg count if your vet recommends twice-yearly monitoring, review deworming effectiveness, update selected vaccines depending on risk, and plan winter nutrition and senior care. Fall is also a common time to recheck dental needs if they were not addressed earlier.

Any time of year: schedule sooner if your horse has weight loss, quidding, bad breath, poor performance, chronic cough, diarrhea, heavy travel, new herd exposure, or a history of vaccine reactions.

Costs vary by region, farm-call distance, and whether services are bundled. Based on recent equine fee data and current practice examples, a wellness exam commonly runs about $40 to $100 before travel fees, with farm calls often adding roughly $60 to $120 or more depending on distance. Individual vaccines often range from about $25 to $85 each, while common combo vaccine visits may total around $65 to $140 before exam and trip charges.

A fecal egg count often falls around $30 to $60, and annual fecal egg count reduction testing adds another lab and follow-up cost. Routine dental exam fees are often about $50 to $75, while maintenance floating commonly lands around $125 to $225, plus sedation that may add roughly $35 to $60. Bundled annual wellness plans for one horse are often in the $500 to $800 range when they include exams, core vaccines, fecal testing, and routine dentistry.

Foals, broodmares, geriatric horses, horses with PPID or metabolic disease, and horses that travel frequently often need schedules that differ from a typical adult pasture horse. Pregnant mares may need pre-foaling vaccine timing, and some breeding farms use specific herpesvirus protocols during pregnancy. Senior horses may need twice-yearly wellness exams, more frequent dental checks, and closer nutrition review.

If your horse has had a prior vaccine reaction, chronic weight loss, repeated colic, poor manure quality, or persistent dental issues, ask your vet to build a more individualized calendar. Preventive care should fit the horse in front of you, not a one-size-fits-all checklist.
