Old School Feeding is still relevant today, and is very close to how we feed and how we think about feeding. Taken from one of the very best German Shorthaired Pointer books ever written. "The Complete German Shorthaired Pointer" by Herr H. F. Seiger, and Dr. F. Vom Dewitz-Colpin, 1951. The information here is a litter hard to read. We highly recommend this book if you are really into the German Shorthaired Pointer.
