Let me do some searchng for you. My 2 favorite foods are Solid Gold and Natura Products (Innova, California Natual..etc.) because they are very healthful, and pretty much what they say is in the bag, I feel confidendent is in the bag (as opposed to ground up possom and phenobarb)..so check on those websites if you get a chance before I do, and see if any fit the fat content you'll likely be looking for a senior or low cal food, you may have to add some supplements like NaturesFarmacy.com Dogzyme ultimates or Missing Link.
