Fido. Fluffy. Little Trouble-maker.

Whatever you call them, we know you call them family. Pets are the heart and soul of Merial’s business, as well as of families the world over. Through products for disease prevention and management, plus educational resources and tools, we help vets and owners collaborate on wellness plans through the entire lives of these beloved companions.

Animals We Support


Fleas, ticks, and internal parasites like heartworm are the bane of the happy dog's existence. Merial produces industry leading solutions to these common and potentially dangerous pests. Vets around the world recommend and prescribe these products to their clients, along with our range of vaccines to help protect pooches against serious diseases like rabies, distemper, parvovirus, and more.


Feline family members have special health and wellness needs, so Merial's solutions are uniquely targeted. Our flea, tick, and heartworm preventives are formulated and dosed specifically for kitties' systems. We've also created the industry's only complete line of feline vaccines free of adjuvants for rabies, feline leukemia, and other common illnesses.

Promoting Responsible Pet Ownership

Thanks to widespread pet vaccination, rabies in domestic animals has dropped dramatically in many regions of the world in recent decades. Nevertheless, each year about 70,000 people globally still die from rabies, and more than 95% of cases are caused by bites from unvaccinated dogs, mostly in rural parts of Asia and Africa1.

So remember the bigger picture: vaccinating your pets is not only about their health. It’s also a way to help protect your wider community’s pets, families, and wildlife from deadly communicable diseases like rabies. Play your part: work with your vet on the right vaccination plan for your animal.

Passionate about pets

Pet shelters, service dog training centers, and more—through our community outreach efforts, Merial supports those organizations, programs, and people devoted to the animals that share our lives.
