I feed this to my seniors: http://www.holisticselect.com/senior-dry-dog-food-chicken-meal-and-rice#guaranteed-analysis
Because it is 10% fat. I also add some additional protein. Usually enough to bring it to about 28%. They formulated this product a number of years ago. I have never fed a senior food until they came up with this. They used to be all crap. They finally got the right idea on protein and old dogs.
The fat is the problem with my guys. I need to keep the protein up, but with 16% fat plus, they gain too much weight over 9 years of age.
My 13 year old senior has been doing great on Pinnacle Salmon and Potato 27/14. He is active for his age but has slowed down. He still maintains solid muscle mass and I have not had issues with weight.
