As a Horse Barn Assistant, your days will generally include feeding and watering horses, mucking out stalls, cleaning the barn, and assisting with turnout and bringing horses in from pastures. You may also help with grooming, basic horse health checks, replenishing supplies, and maintaining cleanliness and order in storage areas. Depending on the facility, you might help with exercise routines or assist trainers and veterinarians during visits. The role is hands-on and often involves working early mornings, weekends, and holidays as part of a team committed to high-quality animal care.
