Bests & Worsts Reviews from Amazon

I have been feeding this food to my dog for a few years with no problems. We received a new bag on March 9th. 4 days later my dog was vomiting and extremely lethargic. I thought she was sick so I kept an eye on her but she wouldn't eat her food for two days. I realized she would eat treats and other things but had no interest in her food. After looking at other reviews I realized it's the food that's making her sick. We switched to different food and she's eating and back to her normal self. This food, at least this batch, has gone bad. I will not buy this again and want my money back for this 40+ pound bag that we just opened.
