The year was 1939 when a young blind man named Morris Frank was traveling the country with his dog, Buddy. Buddy was suffering from end-stage kidney disease, and Mr. Frank asked Dr. Mark Morris Sr. for help.

Dr. Morris believed he could find a nutritional solution to Buddy’s issues, so he developed a new pet food with his wife, Louise Morris, in their kitchen.
