Boehringer Ingelheim’s U.S. Animal Health Business

Preventing disease. Pioneering innovation. Promoting animal well-being.


Dogs and cats enrich our lives. They make the world a better place. So we’re proud to focus with passion on keeping pets healthy. We’re also proud that so many veterinarians recommend our products so often.

NexGard® (afoxolaner) is the #1 product on the market to protect dogs from fleas and ticks. Our HEARTGARD® Plus (ivermectin/pyrantel) chew, made with real beef, prevents heartworm disease. And FRONTLINE® Plus brand products have been protecting dogs and cats from fleas and ticks for almost 20 years.

We make these and other products for dogs and cats with one goal in mind – to keep pets healthy.
