In the late 1930s, Morris Frank, a young blind man, was touring the country with his guide dog, Buddy, promoting Seeing Eye™ dogs. However, Buddy, a German shepherd, was suffering from kidney failure, and Mr. Frank asked Dr. Mark Morris Sr. for help. Dr. Morris believed Buddy's illness was the result of poor nutrition, so he developed a new pet food with his wife, Louise Morris, in their kitchen. Louise and three other women continued making the food in the Morris family basement, storing it in Ball™ jars. Raritan Ration B was the forerunner of Hill's™ Prescription Diet™ k/d™ Canine and is developed for dogs with renal failure and insufficiency.
Dr. Morris mailed the food to Mr. Frank, who was traveling the country with Buddy. However, the jars often broke in transit. Morris Frank arranged for delivery of several thousand cans and a hand-operated canning machine to Dr. Morris. His staff then started canning food.
