Innovation, Talent & Clinical Research

Hill's long-term investment in learning, technology and talented scientists has helped us develop industry-leading product innovations including the most extensive range of clinical nutrition products for sick, at-risk and healthy pets.

Hill's employs over 220 veterinarians, Ph.D. nutritionists and food scientists who work passionately to create foods that transform lives.

Our scientists author more than 50 research papers and textbook chapters each year and are invited to teach at leading schools of veterinary medicine all over the world.

Our foods have been trusted by millions of pet owners since 1939, and today, countless veterinarians recommend and feed their own pets Hill's products more than any other brand of pet food.

Consistent with Evidence-Based Medicine used by human physicians, Hill’s performs randomized, blinded and controlled clinical feeding studies. We are proud to be the first pet food company to apply the concept of evidence-based clinical nutrition to the development of pet food.

In some cases, we’ve taken steps that not even human medicine has been able to. We are the only pet food company that we know of using nutrients to change how genes are expressed to help manage disease conditions.

Some of the analytical methods employed at the Pet Nutrition Center Analytical Research lab include gas chromatography, mass spectroscopy, liquid chromatography and inductively coupled plasma optical emission spectrometry.
