I agree completely with the Nut and Marie. I feed my three dogs, one of which was 15 years old last September high quality, high protein foods. All are grain free. I feed a rotational diet to all three and the proteins in the foods I feed vary. The lowest protein I feed is 38% and the highest is around 54%. I’ve been feeding this way for approx. 3 years now and all my dogs are doing really very well. As a matter of fact, since starting the high protein grain free foods my senior is more puppy like than she’d been in the previous years. She used to sleep a lot, had lost interest in most activities and had lost her spunk. As the Nut stated, seniors need more protein not less. It’s antiquated marketing that would have us believe that puppies, adults, seniors, active, less active, yada yada yada all need their own special diets. Puppies would probably do best on an all life stages food with the exception of large breed puppies which need less calcium with the correct ratio of phos. so as to slow (or not speed up) down their growth rate. I don’t have any large dogs but from all I’ve learned on this site I believe what I’m saying about large breed puppies is correct. I may not be wording it correctly. Anyway, seniors do better and need a higher protein food not less.
