Expert nutrition for every dog and cat

Our team of experts

When you want the best for your pets, you want to know that the food you’re giving them has been developed by pet nutrition experts. That’s why we have an experienced team of veterinarians, animal nutritionists, scientists and chemists, as well as specialists in food production, quality, and safety.

Our experts work together to formulate, review, analyze, and approve each Merrick diet to ensure we are crafting the highest-quality and safest food and treats for our dogs and cats.

Quality nutrition you can trust

Merrick is also backed by the nutritional pioneers in the pet food industry. As a Nestlé Purina PetCare business unit, we have access to unparalleled research, experience and resources. Their team of more than 500 nutritionists, veterinarians, behaviorists and researchers around the world are always working to discover nutritional breakthroughs to help advance the lives of pets and help ensure we are delivering high quality, safe nutrition you can rely on for your dog or cat.

Crafted with love for over 30 years

Back in 1988, we got our start in Garth Merrick’s family kitchen and continue to operate our own canneries and dry food production facility in Hereford, Texas. As we say down in Hereford, “this isn’t our first rodeo” – we’ve been delivering the best food ever for the best pets ever for more than 30 years.
