Natural Balance Ultra Premium Is There Something Wrong With Natural Balance Dog Food?

Is there something wrong with Natural Balance dog food? - natural balance ultra premium

My dog ate Natural Balance Ultra Premium Dog Food for more than a month and loves it. I bought Potato and Duck Formula are treated and how it was a different variant. I recently read online articles about the potato and duck formula sick dogs. There was something in their diet, which is manufactured in the United States more. Can I get a little advice about this? My dog is used to visit on Blue Buffalo and had tried to balance of nature, his cousin dog. I learned it was as good as the blue and much less expensive. Well, not so sure. My dog is a miniature schnauzer mix.
