Grains are not typically used as useless fillers. Instead, grains contain carbohydrates that can provide your dogs the energy they need to remain active and energetic throughout the day. When dog food manufacturers remove whole grains from their formula, they usually replace grain-based carbs with other nutrient-rich ingredients.
Some common replacements for carbohydrates normally provided by grains can include:
- Sweet potatoes
Thanks to these substitutes, dog food without grain can contain just as many carbs as regular dog food. In some cases, the carb count may even be higher in an attempt to provide extra energy to larger canines.
Grains also provide necessary protein for your dogs that should be replaced. If your pooch requires a high-protein dog food, it's recommended that the grain-free option you choose contain a substantial amount of meat or other protein-rich ingredients. Whole proteins can be commonly found in chicken, beef, fish, duck and eggs.
