Dogs with certain medical conditions may require a low fat diet (often senior dogs, obesity related conditions, and dogs with kidney or liver disease). Pets who just need to lose a little weight through calorie reduction may also need a little help, and picking the best low fat dog food brand is one of the ways to do this.   There are plenty of pet food brands out there that proudly flash the “reduced fat” label, but it can be difficult to choose the best. Many of these low-fat options lack quality as they reduce the amount of protein in their foods to get rid of this excess fat, leading to unhealthy high-carb, low-protein diets that don’t provide a pup with the nutrition they need. After analyzing hundreds of brands, below we've picked out the best low fat dog food brands ranked from having the lowest crude fat content (4.5%) to the highest among low fat dog foods (14.5%) with a single raw dog food option of lowest fat content (28%).
