The concept of pet foods formulated to benefit dogs with specific health problems was innovated by Mark L. Morris, Sr., a veterinarian who started his first practice in 1928 in Edison, New Jersey, after graduating from Cornell University. At a time when most veterinarians treated mainly livestock and working farm animals, Dr. Morris focused his veterinary practice, the Raritan Hospital for Animals, on the care of companion animals.
At that time, the nascent pet food industry produced two types of foods for dogs: baked biscuits and canned foods that consisted almost exclusively of horsemeat. Most people fed table scraps to their pet dogs; only more affluent, urban or suburban owners augmented their dogs’ diet of leftovers with a commercial dog food.
These products were anything but “complete and balanced” – living conditions caused by the Great Depression meant that only the least-nutritive foodstuffs were going into pet food. Dr. Morris noticed that his veterinary practice saw an unusually high number of dogs with kidney disease, and he speculated that this had something to do with their diets, comprised mostly of poor-quality protein. He started conducting research on pet nutrition; he believed that he could better treat his patients by using proper nutrition from a balanced diet.
Dr. Morris worked with Dr. Jim Allison at Rutgers University’s biochemistry department to develop techniques for diagnosing diseases in small animals and to develop and test recipes for better dog and cat diets; he started selling his first pet food formulas in 1939.
That was the same year that he met Morris Frank, a young man who had lost an eye in an accident as a young child and lost vision in the other in a boxing match as a teenager. Frank traveled to Europe in 1928 to acquire his German Shepherd guide dog, Buddy; shortly after he brought Buddy back to the U.S., Frank started America’s first guide dog school in New Jersey. In 1939, he and Buddy were “The Seeing Eye” guide dog school’s national ambassadors – though Buddy was by then an old dog suffering from kidney disease. Frank sought out Dr. Morris, desperate for anything that might help Buddy.
Dr. Morris formulated a special diet for Buddy, canning it in glass jars in his kitchen with the help of his wife, Louise. Legend has it that the dog’s health improved and soon, this formula – dubbed Raritan Ration B – was in great demand. Frank sent Dr. Morris a canning machine and a commission for thousands of orders. By 1948, with the popularity of the food growing – and no doubt, wearying of operating the canning machine – Dr. Morris took his formula to a Topeka, Kansas, canning company, the Hill Packing Company (named after its founder, Burton Hill), which had been canning dog food (as well as horse meat for human consumption!) since 1930.
The business relationship thrived and by 1948 became a partnership, Hill’s Pet Nutrition. Raritan Ration B was given a new name, “Canine k/d” (for “kidney diet”). Dr. Morris continued to create new formulas for diets that addressed pet health problems and Hill’s produced, packaged, and marketed them. In 1951, Dr. Morris moved his laboratory to Topeka, where new products are developed and tested at the Hill’s Global Pet Nutrition Center to this day.
Mark Morris, Sr., was instrumental in the founding of the American Animal Hospital Association. He also established the Morris Animal Foundation and served as president of the American Veterinary Medical Association.
Mark and Louise Morris had two children, Mark Jr. and Ruth. Mark Jr. earned a doctorate’s degree in veterinary medicine in 1958. After serving in the U.S. Army Veterinary Corps, he completed a Ph.D. in veterinary pathology and biochemistry. Later, he joined Hill’s Pet Nutrition, where he expanded the company’s offerings. In 1968, he oversaw the development of a new line of dog and cat foods called Science Diet, formulated with preventative health in mind. Mark Jr. was a founding member of the American College of Veterinary Nutrition and co-authored Small Animal Clinical Nutrition, the definitive textbook for companion-animal nutrition.
Hill’s Pet Nutrition has been purchased by large corporations twice: Riviana Foods bought the company in 1968, and in turn was purchased by Colgate-Palmolive in 1976. Hill’s is currently ranked fourth on the list of the largest pet food companies in the world, with $2.5 billion worth of sales annually.
