Senior dogs may benefit from lower phosphorus sources (egg whites, some plant proteins).<\/li>\n\n\n\n<li><strong>Quality over quantity:<\/strong> The source and processing method matter more than crude protein percentage. Look for named meat meals (e.g., \u201cchicken meal\u201d rather than \u201cpoultry by-product meal\u201d) for concentrated protein without excess water.<\/li>\n\n\n\n<li><strong>DCM concern:<\/strong> Avoid grain-free diets that rely heavily on peas, lentils, and potatoes as primary protein contributors unless formulated by a veterinary nutritionist.<\/li>\n<\/ul>\n\n\n\n<p>In conclusion, the best protein source for your dog depends on individual tolerance, nutritional needs, budget, and ethical preferences. A diet that includes a variety of high-quality animal proteins (and optionally, well-processed plant or insect proteins) is generally the most robust approach.
