Bringing a New Horse Home: Setup, Quarantine, and First Week Checklist

Set up a dedicated arrival space before the trailer pulls in. Ideally, this is a separate stall or paddock with no nose-to-nose contact, its own water source or buckets, and tools that are not shared with resident horses. Use safe fencing, remove toxic plants and loose wire, and check gates, latches, lighting, and footing. Keep a halter, lead rope, thermometer, manure fork, muck bucket, and disinfectant nearby so daily care stays organized.

Have records ready in one folder or app: bill of sale or transfer paperwork, vaccination history, deworming history, dental notes, farrier dates, microchip information if available, and emergency contacts. If the horse crossed state lines, many states require individual identification and a Certificate of Veterinary Inspection, and some also require proof of a negative Equine Infectious Anemia test. Requirements vary by state, so confirm them before transport and keep copies on hand.

A practical startup supply budget for one horse often runs about $150 to $500 for separate buckets, feed tubs, a digital thermometer, basic first-aid items, disinfectant, and quarantine signage. If you need temporary fencing, extra stall mats, or a second paddock lane, the setup cost range can rise to $500 to $2,000 or more depending on your property.

Quarantine does not mean your horse is sick. It means you are reducing risk while the horse settles in and while you watch for fever, cough, nasal discharge, diarrhea, poor appetite, or behavior changes after transport. AAEP guidance supports isolating new arrivals for about 7 to 14 days in lower-risk situations, while Merck and other infectious-disease guidance often recommend 21 days before commingling, especially for horses returning from events or arriving from unknown-risk facilities.

In practical home management, many pet parents and barns use a 14-day quarantine as a minimum if the horse is healthy, paperwork is current, and risk is low. A 21-day plan is more cautious and may be a better fit if the horse traveled long distance, came from a sale barn, had recent show exposure, or will live near pregnant mares, foals, or medically fragile horses.

During quarantine, care for resident horses first and the new horse last. Use dedicated buckets, grooming tools, and manure tools. Wash hands between horses, change gloves when needed, and avoid sharing tack. If the new horse develops fever, cough, nasal discharge, diarrhea, or neurologic signs, stop all horse movement on and off the property and call your vet right away.

Unload quietly and give the horse time to look around. Offer fresh water right away and provide familiar hay if possible. Many horses drink less during travel, so hydration and manure output are important on day one. Take a rectal temperature after the horse has settled, then continue at least twice daily for the first 48 hours after a long trip. Travel stress can contribute to colic risk and can also set the stage for transport-associated respiratory disease.

Do a hands-on check: attitude, breathing effort, gum moisture, digital pulses if you know how to assess them, skin wounds, leg swelling, manure amount, and urine output. Write down what you see. A normal baseline helps you and your vet notice subtle changes sooner.

Avoid grain overload, hard work, and immediate herd turnout on arrival day. If the horse seems anxious, keep the environment quiet and predictable. Some horses benefit from a small paddock or hand-walking, while others settle better in a stall with hay. Match the plan to the horse and your vet's guidance.

The safest feeding plan is usually the most familiar one. Ask what hay, concentrate, supplements, and feeding schedule the horse was on before transport. Sudden diet changes can increase the risk of colic, loose manure, or reduced intake. If you need to switch hay or grain, make the change gradually over 7 to 10 days when possible.

For most adult horses, forage should stay the foundation of the diet. Offer clean water at all times and monitor how much the horse drinks. Some horses drink better if the water tastes familiar, is slightly warmed in cold weather, or is offered in a clean bucket rather than an automatic waterer. If your horse is not drinking well, has dry manure, or seems tucked up after travel, call your vet.

Hold off on adding multiple supplements right away unless your vet recommends them. The first week is about stability. Good notes on appetite, water intake, and manure are often more useful than making several changes at once.

Plan a baseline visit with your vet soon after arrival, especially if records are incomplete or the horse is new to your area. This visit may include a physical exam, review of vaccination timing, fecal testing or a deworming plan, body condition scoring, dental review, and discussion of farrier needs. Vaccination plans should be individualized by age, use, travel exposure, and local disease risk. AAEP lists tetanus, Eastern/Western equine encephalomyelitis, West Nile virus, and rabies as core vaccines for horses in the United States, with influenza and EHV-1/4 often added based on risk.

If the horse will travel, show, board, or mix with many horses, ask your vet whether influenza and herpesvirus boosters are due. Vaccines work best when given before likely exposure, not after a problem starts. Your vet can also help you decide whether any risk-based vaccines make sense in your region.

Typical 2025-2026 U.S. cost ranges for early preventive care are about $50 to $100 for a routine wellness exam, $40 to $80 for a standard Coggins test, $30 to $55 for an interstate health certificate when needed, and roughly $65 to $200 for a farm call depending on distance and practice structure. Bundled spring or annual wellness visits with core vaccines and Coggins commonly total about $280 to $500 per horse before or after travel fees, depending on region and how many horses are seen on the same visit.

See your vet immediately if your new horse has colic signs, repeated pawing, rolling, no manure, labored breathing, a fever, marked depression, neurologic signs, severe diarrhea, or refuses water. These problems can escalate quickly, and recent transport can make early signs easy to miss.

Call your vet the same day for a temperature above your horse's normal baseline, new cough, nasal discharge, swollen legs, reduced appetite, fewer manure piles, or unusual lethargy. Transport-associated pneumonia, often called shipping fever, may not show up until a day or two after travel.

If one horse on the property develops a possible contagious illness, tighten biosecurity immediately. Separate horses, stop sharing equipment, and pause movement on and off the farm until your vet helps you make a plan.

• Prepare a separate stall or paddock before arrival.
• Confirm paperwork: identification, Coggins, health certificate if required, vaccine history, and emergency contacts.
• Offer fresh water and familiar hay on arrival.
• Record temperature, appetite, water intake, manure, and attitude at least twice daily for several days.
• Keep quarantine tools separate and care for resident horses first.
• Delay direct contact with resident horses until your vet is comfortable with the risk.
• Introduce any feed changes gradually.
• Schedule a baseline exam, vaccine review, and preventive-care plan with your vet.
• Arrange farrier follow-up if hoof balance or shoeing is overdue.
• Keep transport, turnout, and training light until the horse is eating, drinking, and acting normally.
