Review on Blue Buffalo Wilderness High Protein, Natural Large Breed Dry Dog Food, 24-lb by Lisa Volkman

Normally our dog loves this food. He's been eating it for a few years. He ate the very last bag, which was delivered on November 15th, on the first day and then became very ill. He lay on the couch for a few days and then finally started eating snacks and wet food. We took him for walks and he really got better, he ran. When we got home he actually ate some more of that food as he was hungry. The next day he got sick again and didn't eat. We think it has to be this meal. Bad batch maybe? I bought another kibble from the store, he eats it, but this one doesn't touch it. Has anyone else had problems with this food lately?
