Try one bag, I was not dissapointed.
"A very picky 18 year old Yorkie, is finally eating and gaining weight. I honestly believe this has and will continue to extend his life. He used to have stomach issues and nothing stayed in him. No longer the case. I wish I found this food years ago. He also had 3 surgeries due to calcium oxolate crystals and this food has also kept him clear of those. Highly recommend trying the brand."
