Petunia was 25 lbs at her heaviest and we had a pancreatitis scare. The vet told me I needed to change her diet to a low fat food. The issue we had is she has food sensitivities and I had a hard time finding one that was low fat, palatable to her and that didn't have anything in it that she couldn't have. I did a lot of research and I found The Honest Kitchen Zeal. It was the lowest fat, human quality grain free food I could find. Petunia LOVED it from day 1 and between the new food and us being more active she lost about 8 lbs! She barks for her meals now which she has NEVER done - she's a very picky eater. I am so thankful for the Honest Kitchen!!!
