Bests & Worsts Reviews from Amazon

I've given my dogs this food several times with no problem. I ordered 2 boxes from amazon of multiple flavors and my 2 dogs threw up the 3 times I gave it to them. Thinking it was my dogs and not the food, I gave the boxes to my mom who also has used this food and her dog threw up every time he ate it as well. I'm not sure what's wrong with the storage or batch of food but something is clearly not healthy for the dogs. DO NOT PURCHASE.
