Dog Food

Yesterday I read an article about the Purina Beneful dog food and its effects to dogs.  Some have died from ingesting this food because it contains an ingredient found in Anti-freeze.  As is common knowledge, Anti-freeze is harmful to dogs and cats.  I cannot recall the number of complaints and cases suing the company, but it is an incredible amount.
As some of you have read in previous posts, our dog, K.B., has been having health issues.  The vet has determined that it is a food allergy of some kind.  After reading the article yesterday, I began to wonder.  Is K.B. suffering from this effect?  She was eating Purina Beneful Healthy, which is on the list, before switching her to BLUE.  While eating the Purina brand, she had diarrhea (one symptom).  Lately, she has been continuously getting a bacterial infection that makes her have skin infections.
I talked with Forrest about this and he is going to mention it to the vet next time.
Unfortunately, we probably cannot prove it now, but I am posting this to make awareness.
