Bests & Worsts Reviews from Amazon

If you notice in my picture, there are two different colors. The dark food is the food I got from Amazon and the lighter food is food I got from the grocery store. They are the same exact brand of food. My dogs were not excited to eat the dark food but scarfed down the light food. I was curious so I tried biting a piece of both and I had a really hard time buying the darker food while the light food practically crumbled when I bit it. I've bought 2 bags of this from Amazon and both were this dark.
