Annamaet has a grain free light formula. Annette's Chloe looks great on it. It is low fat. The higher protein might help Georgia with her issues. It is chicken based, however. I would use something that is NOT cellulose powder filled. Changeover gradually. I used Nutro for close to 20 years, but the quality dropped a lot after one of the company sales. The 2006-7 mela poisoning finished me, and one of my dogs.
One feeds a lot less of Annamaet regular dog food than other brands I have used. There are grain inclusive lower fat formulas, too.
