Preventive Care for Horses — HorseVeterinarian.AI

Prevention Is the Most Cost-Effective Equine Health Investment

The diseases, dental problems, and parasite burdens that cost the most to treat are overwhelmingly the ones that appropriate preventive care prevents or catches early. A consistent annual wellness program — vaccinations on schedule, targeted deworming based on fecal egg counts, biannual dental exams, and an annual veterinary examination — is the foundation of a long, healthy, productive equine career.

The guides below follow AAEP (American Association of Equine Practitioners) guidelines and current evidence-based veterinary practice. Each covers what the protocol is, why it matters, how it works, and the specific questions worth asking your veterinarian.

Preventive care protocols should be developed in partnership with your licensed equine veterinarian, who can tailor recommendations to your horse's age, use, geographic location, and individual risk factors. The guides below provide educational context to support those conversations. Find an equine vet →

Core Preventive Health Protocols

💉 Core + Risk-Based

Vaccination Guide

AAEP core vaccines are recommended for every horse regardless of use or location: EEE/WEE, Tetanus, West Nile Virus, and Rabies. Risk-based vaccines — Influenza, EHV, Strangles, Potomac Horse Fever — are determined by your horse's exposure risk, travel schedule, and geographic region. This guide explains every vaccine category, the schedule, and what to discuss with your vet.

🪲 Targeted Selective Treatment

Strategic Deworming Programs

The modern evidence-based approach uses fecal egg counts (FEC) to identify which horses in a herd actually need treatment — rather than treating all horses on a fixed calendar schedule that drives anthelmintic resistance. Bot flies require a separate targeted fall treatment with ivermectin or moxidectin. This guide explains how to build an effective, resistance-conscious program.

🦷 Annual to Biannual

Dental Care

Equine teeth erupt continuously throughout life and require professional floating to remove sharp points that lacerate cheeks and affect bit acceptance. Young horses (under 5) and seniors (over 20) need exams every 6 months — adult horses annually. Dental disease is consistently underrecognized because horses mask discomfort until it becomes significant.

Annual Wellness Exam

An annual examination by a licensed equine veterinarian provides a complete health baseline, catches emerging problems before they become serious, and is the right time to review vaccinations, deworming results, body condition, and any behavioral or performance concerns. For horses over 15, biannual exams and ACTH testing for Cushing's screening are increasingly recommended.

Biosecurity Protocols

Biosecurity practices — new horse quarantine, event return monitoring, equipment disinfection, and handler protocols — prevent the introduction and spread of infectious diseases including Strangles, EHV, Influenza, and Pigeon Fever. The cost of preventing an outbreak is a fraction of the cost of managing one.

Dental Exam	Adult horses annually; under 5 or over 20 every 6 months	Schedule with annual wellness exam or separately
Annual Wellness Exam	Full physical, BCS, bloodwork discussion, vaccination and deworming review	Schedule same time each year; spring is common
ACTH Testing	Screen for Cushing's (PPID) — recommended from age 10+	Spring for clearest results; fall if symptoms present
Coggins (EIA Test)	Required for travel and most competitions; 6 or 12 month validity varies by state	Annual; time with spring vet visit
