Bests & Worsts Reviews from Amazon

We have been using Purina One Smartblend for over 7 years without issue. Our dog loves the food. Only recently did we begin using the Amazon subscription service. There were no issues with the first couple deliveries, but this last one was different. The dog food has little white specs in it. Initially, we thought it was an additive not completely mixed in or something new to the formula, but a month into using it and half way through the bag, we have found bugs and insect larvae crawling around inside the food bin. We do not have the original packaging to provide a lot number. I don't know if this is something that happened because of an Amazon storage issue or a production problem with Purina. My faith in the product is strong. I immediately purchased another bag of Purina One to replace this one, but it was from Walmart, not Amazon. I have cancelled my subscription because of this. The couple dollars I saved using Amazon will be more than offset my veterinarian bills.
