Bests & Worsts Reviews from Amazon

This was the 2nd bag that I have purchased from Amazon, the first bag was fine. I noticed when I opened this bag that the kibble looked different. After feeding my dog this kibble for a few days I noticed that she was getting bumps on her back and scratching/chewing a lot. We took her to the vet and they said it is most likely caused by something in her diet. We quit feeding her the food and over the last week her condition has improved but she is still experiencing discomfort. I am not sure if the food was counterfeit or if it had something toxic in the ingredients. When I contacted Amazon they quickly refunded the money even though I did not have the original package any longer. They did not want me to send the product back, they told me I could throw it away. I took a picture of the bad kibble (on the right in the photo) along side good kibble (on the left side in the photo). You can clearly see that the bad kibble is smaller and shiny. I have also contacted Blue Buffalo to see if they want to investigate the bad kibble.
