Bests & Worsts Reviews from Amazon

My dog used to LOVE this food before they completely changed it. I've been purchasing this food for quite some time, and have been purchasing Blue Buffalo food for my dog ever since he was a puppy. Just last week I received another bag from Amazon, and my dog stopped eating as soon as I switched to the new bag (both bags Freedom Grain Free). I noticed that the bag was slightly different from the previous bags, with a more plasticky feel compared to what I would previously describe as a paper-like bag. Since my dog is somewhat picky, I decided that perhaps the change in bag material affected the taste enough for him to notice. I trekked to the local pet store, and discovered that they had both new and old-style Blue Buffalo bags in stock for a variety of the foods, with no differentiation. I purchased an old-style bag to see if he would eat it. As soon as I poured out some food, I noticed a difference between the two bags. The new pellets are much larger than the old ones. After putting his bowl down, he immediately gobbled it up as if he hadn't eaten in days (he hadn't). I then examined the bags. The new-style food suggests that a dog of size 50-70lb should consume 3.5 to 4 cups of food per day, while the old-style food offers a suggestion of 2.5 to 3.25 cups. That means there's 1.5 times as much food in the old bag of the same size and price as the new bag. The caloric differences are 360 Kcal/cup compared to 370 Kcal/cup. Not a huge difference, but one worth noticing. I'm sending this bag back, and it looks like I may need to find a new brand to feed to my dog.
