What should ideally dominate the top ingredients listed on traditional dry kibble for a Westie?

Identifiable, named meat sources such as chicken, lamb, or fish

When evaluating commercial dry kibble intended for a breed with specific nutritional demands like the Westie, the integrity of the protein source is paramount. The ingredient list should begin with clearly named, identifiable sources of animal protein, such as specifying 'chicken' or 'fish' rather than using ambiguous terms like 'meat by-products' or unspecific 'meat meal.' This ensures that the diet is founded on high biological value animal protein necessary for muscle support. If grain or plant-based fillers occupy the initial positions in the ingredient list, the actual percentage of usable animal protein may be significantly lower than what the guaranteed analysis suggests.
