Our Company

The Company Inspired by a Guide Dog

Today, Hill's® Pet Nutrition carries on the tradition of caring that began in 1939 with one remarkable veterinarian. Our Healthy Advantage®, Prescription Diet®, Science Diet® and Ideal Balance™ pet foods offer the highest-quality pet nutrition available. We're making a difference for people and their pets all over the world.

The Hill's® pet food lines began in 1939. Dr. Mark L. Morris Sr. believed certain health conditions in pets could be managed through carefully formulated nutrition. His ideas were visionary in veterinary medicine, and he soon had the chance to prove his theory.

A young blind man named Morris Frank asked Dr. Morris if anything could be done to save his guide dog, Buddy, who was having kidney health issues. The result of Dr. Morris' efforts was the nutritional formulation that became the first product in the Hill's Prescription Diet line of therapeutic pet foods, and the world's first pet food designed for kidney health. Soon after, Hill's Pet Nutrition was founded and the field of clinical nutrition sprang to life. That first therapeutic dog food evolved into Hill's® Prescription Diet® k/d®, which is still sold today.

The Search for Discovery that Defines Us

In 1928, Dr. Mark L. Morris Sr. established Raritan Hospital for Animals in Edison, New Jersey. At the time, this was one of only two small animal hospitals in the United States. Dr. Morris believed managing nutrition could have a positive effect on the health of companion animals. He developed the first Prescription Diet® pet food in an attempt to help one of America's first guide dogs who was suffering from kidney disease. Now decades later, Hill's® Pet Nutrition is working to bring pets long, healthy lives. Read the complete story of Hill's® Pet Nutrition.

The Story of Hill's® Pet Nutrition

We believe quality care for pets includes optimal nutrition, veterinary healthcare, daily exercise and an enriching environment with lots of love. All pets at Hill's® Pet Nutrition live in such an environment. We only use compassionate, non-invasive methods necessary to develop nutritional technology so dogs and cats around the world live long, healthy lives. Our breakthroughs in pet nutrition are unmatched in the pet food industry and we've built our business and reputation on always practicing the highest ethical standards.

Every day we prove that quality scientific technology and compassionate animal care go hand-in-hand for the improvement of pets' healthy lives. This is why Hill's® only supports and exercises the responsible, caring and humane treatment of dogs and cats. All studies conducted or supported by Hill's® - whether at the Hill's® Pet Nutrition Center or externally in consumers' homes, veterinary schools or elsewhere - must comply with the following stringent Hill's® policies to ensure exceptional animal care:

Hill's® does not participate in studies that jeopardize the health of dogs and cats. All Hill's®-supported studies are designed to maintain and improve the animals' health. No study will be performed on dogs or cats that requires euthanasia.

When studying how a nutrient is absorbed, distributed, stored, used and released by a dog's or cat's body, we only use research methods that are the veterinary equivalent of human nutritional or medical studies. Hill's® does not support or conduct studies that cause pain or hurt the dogs or cats. This is based on the belief that what is painful to humans is also painful to dogs and cats.

We only conduct studies if we have compelling evidence that we can improve the health and welfare of companion animals. These studies often result in breakthrough nutritional findings, improving the lives of millions of dogs and cats.

We continually strive to find ways to reduce dependence on animal research. A substantial number of dogs and cats participating in our feeding studies are involved in in-home tests. Our veterinarians and nutritionists are skilled at developing methods that simulate animal systems. For example, we have developed and published a mathematical formula, based on the nutrient profile of the food that accurately predicts the pH of feline or canine urine without animal testing.

To assure pet owners that our therapeutic foods are safe and effective, we support studies using pets with naturally occurring diseases or conditions. We do not participate in studies in which surgical or non-surgical methods are used to create or simulate disease conditions.

The Hill's® Pet Nutrition Center and any external facility Hill's® supports must meet or exceed all industry regulatory standards for animal care. For all studies conducted at external facilities, we appoint and fund pet advocates, responsible for ensuring each pet's compassionate care, which has the key components of providing exercise and a socially-enriched environment.

We publish the results of our studies to advance the knowledge of nutritional health care and to help prevent the unnecessary repetition of studies involving dogs and cats.

Hill's® only uses data from animal studies that are in the public domain, either previously published or were conducted under this Global Animal Welfare Policy.

Dr. Mark Morris Sr.

Dr. Mark Morris Sr.

Born in 1901, Dr. Morris was a founder of Hill's Pet Nutrition. A visionary in the area of clinical nutrition, he believed nutrition could be used to aid pets with certain diseases. At a time when most veterinary work revolved around farm animals, he cared for companion animals and their owners, opening Raritan Hospital for Animals in Edison, New Jersey, in 1928. This was the second exclusively small animal hospital in the United States.

Dr. Mark Morris Sr. with dog in the lab

Dr. Morris had new ideas for the management of diseases in companion animals. He worked with Dr. Jim Allison at Rutgers University's biochemistry department to develop techniques for diagnosing diseases in small animals. His ideas were new and not always well received, but Dr. Morris soon established himself as an expert in pet food.

After he joined with the Hill Packing Company in Topeka, Kansas, to can his pet foods, Dr. Morris established a charity for small animals. The Morris Animal Foundation continues to provide funding for small animal research, wildlife research and funding for veterinary student scholarships. Today it's the largest nonprofit foundation in the world for companion animal and wildlife health studies, with funds approaching $50 million since its founding in 1948.

Science Diet bags

Throughout his life, Dr. Morris was active in the small animal arena. He was the first president of the American Animal Hospital Association (AAHA) and president of the American Veterinary Medical Association (AVMA). He also led a committee to establish nutritional standards for pet foods and these efforts later formed the basis used today be the Association of American Feed Control Officials (AAFCO).

Dr. Morris died in 1993 at the age of 92.

Dr. Mark Morris Jr.

Dr. Mark Morris Jr.

Dr. Mark Morris Jr., son of Hill's Pet Nutrition founder Dr. Mark Morris Sr., continued the legacy his father began in pet nutrition.

Growing up in a house where his mother was cooking his father's Prescription Diet® pet foods, Mark Morris Jr., decided to continue his father's lifelong work in pet nutrition. Dr. Morris Jr., noticed a demand for consistent, high-quality pet food for use in research. At the time, pet food was not carefully regulated, so research scientists had difficulties maintaining the integrity of their work.

Science Diet canned formula

As a result, Dr. Morris Jr., developed a food formula for healthy pets. In 1968, the food line was made available through veterinarians and pet professionals as Hill's® Science Diet®. The line has continued to expand, and today includes more than 50 Science Diet brand pet foods and more than 60 Prescription Diet™ brand pet foods formulated for many life stages and special needs in healthy pets.

Small Animal Clinic Nutrition books

Dr. Morris Jr., is widely considered the father of small animal wellness nutrition, and also worked to establish standards for feeding prepared foods to zoo animals. He was a founding member of the American College of Veterinary Nutrition (ACVN) and authored numerous publications on nutritional management of disease, lecturing around the world to practicing veterinarians, veterinary students and companion animal owners. Dr. Morris Jr., co-authored "Small Animal Clinical Nutrition," the definitive textbook for companion animal nutrition and the most widely used source on the subject around the world.

Dr. Morris Jr., died on Jan. 14, 2007 at the age of 72.
