What to Look For:
• High-quality protein sources: Choose foods with named animal ingredients like chicken, salmon, or lamb as the first ingredient. • Whole food ingredients: Opt for foods that list whole fruits and vegetables instead of generic terms like "fruits" or "vegetables." • Moderate fat content: Grain-free diets often require more fat to maintain energy levels. Look for a balance between protein, fat, and carbohydrates. • No artificial preservatives: Choose foods with natural preservatives like vitamin E or tocopherols instead of artificial additives.
What to Avoid:
• Filler ingredients: Avoid foods containing wheat, corn, or soy as they can cause digestive issues in some dogs. • Over-reliance on legumes: While legumes are a decent protein source, excessive amounts can lead to kidney strain and other health problems. • Unbalanced nutrient profiles: Be wary of foods that prioritize protein over all other nutrients. Look for a balanced formula with adequate fat and carbohydrate content.
