Why the 40 Lb Size Matters
I find the 40 lb bag especially useful because it offers better value for money compared to smaller bags. It also works well if I have multiple dogs or one dog that eats a consistent amount every day. The larger size can save me time, but I make sure I have a cool, dry place to store it properly so it stays fresh.
Ingredients I Pay Attention To
When I evaluate this food, I focus on the quality of the protein source first. I want to see ingredients that help maintain muscle and energy.
