My sister was the one who did all the research and found that your food is the best alternative to buying prescription food. My mom lives on social security, we provide additional help of course, but we needed something that wasn't going to break her bank or ours. The reason my moms dog, O'Henry now eats your food is because he gets bladder stones. He will most likely need surgery again in a couple years, but having this food available for him will definitely help him to make it to the couple year mark or hopefully longer. Just to note he doesn't always eat the chicken, we buy whatever limited selection they have at the local Target near where my mom lives. Thanks for your food. It has really helped all of us feel good about the money we spend and the care we are providing for my mom's dog.
