I switched my 9 year old Silky Terrier, Asta to Blue Buffalo Chicken after I found bits of metal in his Pedigree dog food. That switch was made around August 20th, 2015. After about a week I began to notice small diarrhea spots in the house and Asta would cough up foam. I thought it was left over side effects from the Pedigree. The symptoms have become worse so I checked out this website and DING!!! Everything the previous posters have cited have been happening to Asta. I am ditching the BB and will put him on a chicken and rice diet for the next few weeks and then switch to Hill’s Science Diet. This is just awful and I’m so mad I could spit! I used Pedigree for two decades and never had an issue until recently and now the BB is killing my dog. These companies should conduct a recall and if they can’t produce a safe/healthy dogfood, CLOSE THEIR DOORS! ST, I am so,so sorry to hear about your beautiful Ben and send sincere condolences and best wishes.
