We're for the horse™

At Merck Animal Health, we are driven by one mission - the health and welfare of the horse. Our products, our research and our horse owner education programs are all focused on providing a better life for our equine companions and better medicine for the equine practitioner.

We're for the right combination

Vaccination is critical to maintaining your horse's health. Merck Animal Health is a leader in equine vaccines, with a comprehensive family of safe, effective products. Our four new West Nile virus vaccines help your veterinarian create a customized and flexible program based on your horse's individual disease risk. Visit WestNileEquineVaccines.com to learn more.
